Handling Energized Products

General Safety Practices

Do not touch or tamper with the power supply when the power cord is connected. Line voltages may be present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards may still exist.

Before working on equipment connected to power lines or telecommunication lines, remove jewelry or any other metallic object that may come into contact with energized parts.

Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is provided by connecting the mains plug to a wall socket with a protective ground terminal. If a ground lug is provided on the product, it should be connected to the protective ground at all times, by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in grounded racks and cabinets.

Always make the ground connection first and disconnect it last. Do not connect telecommunication cables to ungrounded equipment. Make sure that all other cables are disconnected before disconnecting the ground.

Some products may have panels secured by thumbscrews with a slotted head. These panels may cover hazardous circuits or parts, such as power supplies. These thumbscrews should therefore always be tightened securely with a screwdriver after both initial installation and subsequent access to the panels.

Connecting AC Mains

Make sure that the electrical installation complies with local codes.

Always connect the AC plug to a wall socket with a protective ground.

The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A. The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A.

Always connect the power cord first to the equipment and then to the wall socket. If a power switch is provided in the equipment, set it to the OFF position. If the power cord cannot be readily disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency switch is installed in the building installation.

In cases when the power distribution system is IT type, the switch must disconnect both poles simultaneously.

Connecting DC Power

Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the ground. Any single pole can be externally grounded.

Due to the high current capability of DC power systems, care should be taken when connecting the DC supply to avoid short-circuits and fire hazards.

DC units should be installed in a restricted access area, i.e. an area where access is authorized only to qualified service and maintenance personnel.

Make sure that the DC power supply is electrically isolated from any AC source and that the installation complies with the local codes.

The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A. The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A.

Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate the circuit breaker of the panel board that services the equipment and switch it to the OFF position. When connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the positive pole and last the negative pole. Switch the circuit breaker back to the ON position.

A readily accessible disconnect device that is suitably rated and approved should be incorporated in the building installation.

If the DC power supply is floating, the switch must disconnect both poles simultaneously.

Connecting Data and Telecommunications Cables

Data and telecommunication interfaces are classified according to their safety status.

The following table lists the status of several standard interfaces. If the status of a given port differs from the standard one, a notice will be given in the manual.

Ports Safety Status

V.11, V.28, V.35, V.36, RS-530, X.21, 10 BaseT, 100 BaseT, Unbalanced E1, E2, E3, STM, DS-2, DS-3, S-Interface ISDN, Analog voice E&M

SELV Safety Extra Low Voltage:

Ports which do not present a safety hazard. Usually up to 30 VAC or 60 VDC.

xDSL (without feeding voltage), Balanced E1, T1, Sub E1/T1

TNV-1 Telecommunication Network Voltage-1:

Ports whose normal operating voltage is within the limits of SELV, on which overvoltages from telecommunications networks are possible.

FXS (Foreign Exchange Subscriber) TNV-2 Telecommunication Network Voltage-2:

Ports whose normal operating voltage exceeds the limits of SELV (usually up to 120 VDC or telephone ringing voltages), on which overvoltages from telecommunication networks are not possible. These ports are not permitted to be directly connected to external telephone and data lines.

FXO (Foreign Exchange Office), xDSL (with feeding voltage), U-Interface ISDN

TNV-3 Telecommunication Network Voltage-3:

Ports whose normal operating voltage exceeds the limits of SELV (usually up to 120 VDC or telephone ringing voltages), on which overvoltages from telecommunication networks are possible.

Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a qualified safety engineer.

Always make sure that the equipment is grounded before connecting telecommunication cables. Do not disconnect the ground connection before disconnecting all telecommunications cables.

Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables. Extra caution should be exercised during thunderstorms.

When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The grounding and bonding of the ground connections should comply with the local codes.

The telecommunication wiring in the building may be damaged or present a fire hazard in case of contact between exposed external wires and the AC power lines. In order to reduce the risk, there are restrictions on the diameter of wires in the telecom cables, between the equipment and the mating connectors.

To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.

Pour réduire les risques s’incendie, utiliser seulement des conducteurs de télécommunications 26 AWG ou de section supérieure.

Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such cases, a notice will be given in the installation instructions.

Do not attempt to tamper with any carrier-provided equipment or connection hardware.

Electromagnetic Compatibility (EMC)

The equipment is designed and approved to comply with the electromagnetic regulations of major regulatory bodies. The following instructions may enhance the performance of the equipment and will provide better protection against excessive emission and better immunity against disturbances.

A good ground connection is essential. When installing the equipment in a rack, make sure to remove all traces of paint from the mounting points. Use suitable lock-washers and torque. If an external grounding lug is provided, connect it to the ground bus using braided wire as short as possible.

The equipment is designed to comply with EMC requirements when connecting it with unshielded twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on certain cables. In such cases, special instructions are provided in the manual.

Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.

The compliance of the equipment with the regulations for conducted emission on the data lines is dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss (LCL).

Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary protection against surges on the data lines. Primary protectors should be provided in the building installation.

The equipment is designed to provide adequate protection against electro-static discharge (ESD). However, it is good working practice to use caution when connecting cables terminated with plastic connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before connecting such cables, discharge yourself by touching ground or wear an ESD preventive wrist strap.

Encapsulation Encapsulating data is a technique used by layered protocols in which a low level protocol accepts a message from a higher level protocol, then places it in the data portion of the lower-level frame. The logistics of encapsulation require that packets traveling over a physical network contain a sequence of headers.

Ethernet A local area network (LAN) technology which has extended into the wide area networks. Ethernet operates at many speeds, including data rates of 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet), 1,000 Mbps (Gigabit Ethernet), 10 Gbps, 40 Gbps, and 100 Gbps.

Ethernet OAM Ethernet operation, administration and maintenance (OAM) are a set of standardized protocols for measuring and controlling network performance. There are two layers of Ethernet OAM: Service OAM (provides end-to-end connectivity fault management per customer service instance, even in multi-operator networks) and Link or Segment OAM (detailed monitoring and troubleshooting of an individual physical or emulated link).

Flow Control A congestion control mechanism that results in an ATM system implementing flow control.

Frame A logical grouping of information sent as a link-layer unit over a transmission medium. The terms packet, datagram, segment, and message are also used to describe logical information groupings.

Full Duplex A circuit or device permitting transmission in two directions (sending and receiving) at the same time.

Office) multiplexer.

FXS (Foreign Exchange Subscriber)

A voice interface, emulating the extension interface of a PBX (or subscriber interface of a CO) for connecting a regular telephone set to a multiplexer.

Gateway Gateways are points of entrance and exit from a communications network. Viewed as a physical entity, a gateway is that node that translates between two otherwise incompatible networks or network segments. Gateways perform code and protocol conversion to facilitate traffic between data highways of differing architecture.

Half Duplex A circuit or device capable of transmitting in two directions, but not at the same time.

Interface A shared boundary, defined by common physical interconnection characteristics, signal characteristics, and meanings of exchanged signals.

IP Address Also known as an Internet address. A unique string of numbers that identifies a computer or device on a TCP/IP network. The format of an IP address is a 32-bit numeric address written as four numbers from 0 to 255, separated by periods (for example, 1.0.255.123).

Jitter The deviation of a transmission signal in time or phase. It can introduce errors and loss of synchronization in high speed synchronous communications.

Laser A device that transmits an extremely narrow and coherent beam of electromagnetic energy in the visible light spectrum. Used as a light source for fiber optic transmission (generally more expensive, shorter lived, single mode only, for greater distances than LED).

Loopback A type of diagnostic test in which the transmitted signal is returned to the sending device after passing through all or part of a communications link or network.

Manager An application that receives Simple Network Management Protocol (SNMP) information from an agent. An agent and manager share a database of information, called the Management Information Base (MIB). An agent can use a message called a traps-PDU to send unsolicited information to the manager. A manager that uses the RADview MIB can query the RAD device, set parameters, sound alarms when certain conditions appear, and perform other administrative tasks.

Multiplexer At one end of a communications link, a device that combines several lower speed transmission channels into a single high speed channel. A multiplexer at the other end reverses the process. Sometimes called a mux. See Bit Interleaving/Multiplexing.

Network (1) An interconnected group of nodes. (2) A series of points, nodes, or stations connected by communications channels; the collection of equipment through which connections are made between data stations.

Node A point of interconnection to a network.

Packet An ordered group of data and control signals transmitted through a network, as a subset of a larger message.

parameters Parameters are often called arguments, and the two words are used interchangeably. However, some computer languages such as C define argument to mean actual parameter (i.e., the value), and parameter to mean formal parameter. In RAD CLI, parameter means formal parameter, not value.

Payload The 48-byte segment of the ATM cell containing user data. Any adaptation of user data via the AAL will take place within the payload.

Physical Layer Layer 1 of the OSI model. The layer concerned with electrical, mechanical, and handshaking procedures over the interface connecting a device to the transmission medium.

Policing A method for verifying that the incoming VC complies with the user’s service contract.

Port The physical interface to a computer or multiplexer, for connection of terminals and modems.

Prioritization Also called CoS (class of service), classifies traffic into categories such as high, medium, and low. The lower the priority, the more “drop eligible” is a packet. When the network gets busy, prioritization ensures critical or high-rated traffic is passed first, and packets from the lowest categories may be dropped.

Protocol A formal set of conventions governing the formatting and relative timing of message exchange between two communicating systems.

Router An interconnection device that connects individual LANs. Unlike bridges, which logically connect at OSI Layer 2, routers provide logical paths at OSI Layer 3. Like bridges, remote sites can be connected using routers over dedicated or switched lines to create WANs.

Routing The process of selecting the most efficient circuit path for a message.

Scalable Able to be changed in size or configuration to suit changing conditions. For example, a scalable network can be expanded from a few nodes to thousands of nodes.

Serial Transmission A common mode of transmission, where the character bits are sent sequentially one at a time instead of in parallel.

SFP (Small Form-factor Pluggable)

A compact optical transceiver used in optical communications. It interfaces a network device (a switch, router or similar device) to a fiber optic or unshielded twisted pair networking cable. It is a popular industry format.

Single Mode Describing an optical wave-guide or fiber that is designed to propagate light of only a single wavelength (typically 5-10 microns in diameter).

Synchronous Transmission

Transmission in which data bits are sent at a fixed rate, with the transmitter and receiver synchronized.

T1 A digital transmission link with a capacity of 1.544 Mbps used in North America. Typically channelized into 24 DS0s, each capable of carrying a single voice conversation or data stream. Uses two pairs of twisted pair wires.

Telnet The virtual terminal protocol in the Internet suite of protocols. It lets users on one host access another host and work as terminal users of that remote host. Instead of dialing into the computer, the user connects to it over the Internet using Telnet. When issuing a Telnet session, it connects to the Telnet host and logs in. The connection enables the user to work with the remote machine as though a terminal was connected to it.

VLAN-Aware A device that is doing the Layer 2 bridging according to the VLAN tag in addition to the standard bridging parameters. A VLAN-aware device will not strip or add any VLAN header.

ETX-202A Ver. 1.2 Overview 1-1

Chapter 1

Introduction

1.1 Overview

ETX-202A is a carrier-class demarcation device owned and operated by the service provider and installed at the customer premises, serving as a clear demarcation point between the user and operator networks.

Two Ethernet network ports as well as up to four Ethernet subscriber ports use copper or SFP-based interfaces.

The SFP-based Ethernet ports accommodate a wide range of Fast Ethernet and Gigabit Ethernet SFP transceivers, allowing service providers to seamlessly connect customers located at different distances from the device.

The network ports support 1:1 or LAG link aggregation. At the physical layer, ETX-202A supports autonegotiation and fault propagation. ETX-202A delivers Ethernet E-line services (EPL and EVPL) and is MEF 9 and MEF 14 certified.

ETX-202A supports powerful bandwidth profiles such as CIR/CBS and EIR/EBS for differentiated Ethernet services and includes comprehensive Ethernet OAM (Operation Administration and Maintenance) capabilities together with SLA monitoring per Flow or Flow.Cos. The unit can be managed via a local terminal port, via a dedicated out-of-band Ethernet port or in each of the user or network ports.

Device Options

Several versions of the unit are available, offering different combinations of Ethernet ports and enclosures:

• Network ports: up to two SFP-based fiber optic or 10/100/1000BaseT electrical

• User ports: up to four SFP-based fiber optic or 10/100/1000BaseT electrical

• Enclosure: metal, 8.4” (unit with single power supply) or 17.4” (unit with dual power supply).

Chapter 1 Introduction Installation and Operation Manual

1-2 Overview ETX-202A Ver. 1.2

Applications

ETX-202A delivers Ethernet services as defined by the MEF standards:

Figure 1-1. EPL Service

Figure 1-2. EVPL Service

Features

Service Types

ETX-202A provides port- and flow-based services.

Port-Based Service

In a typical port-based application ETX-202A receives different services via different user ports (Figure 1-3). This method achieves clearer service separation, it does not require any marking for CoS and provides straightforward SLA measurement.

Figure 1-3. Port-Based Service

Installation and Operation Manual Chapter 1 Introduction


Flow-Based Service

In a typical flow-based application different services are assigned to different Ethernet flows received by the same user port (Figure 1-4). This provides a cheaper, more scalable solution, with a possibility of mixing different service types.

Figure 1-4. Flow-Based Service

Network Interface

ETX-202A includes up to two Ethernet network ports. The network ports use industry-standard Gigabit or Fast Ethernet SFP (Small Form-Factor Pluggable) hot-swappable optical transceivers. ETX-202A can also be ordered with built-in 10/100/1000BaseT ports supporting autonegotiation and flow control.

User Interface

ETX-202A subscriber ports terminate in up to four built-in 10/100/1000BaseT ports or SFP-based fiber optic ports. The electrical ports support autonegotiation and flow control.

Link Redundancy

The unit supports network link redundancy in a LAG architecture. Dual homing technology in a 1:1 architecture allows ETX-202A to be connected to two different upstream devices.

Traffic Mapping

The ingress user traffic is mapped to the Ethernet flows (EVCs) using the following per-port criteria:

• Port-based (All-to-one bundling)

• User port + CE-VID

• User port + CE-VLAN priority

• User port + DSCP

• User port + ToS

• Network port + SP-VLAN

• Network port + SP-VLAN + SP-VLAN priority.

ETX-202A supports up to 30 Ethernet flows.



Services

Each flow can either have a single service assigned to it or up to eight services which are differentiated by SP-VLAN P-bits (flow.CoS),.

Policing and Bandwidth Profiles

Two policers (upstream and downstream) are applied per service. The policers operate according to the dual token bucket mechanism (CIR+CBS, EIR + EBS)

Traffic Prioritization and Quality of Service

Once traffic was classified to Flow or Flow.CoS, it can be mapped to SP (Strict Priority) queues or WFQ (Weighted Fair Queues). The section below explains both options.

• SP. The data flow set to the highest priority is transmitted first. If this data flow stops, all tasks at lower priorities move up by one priority level. For example, the data flow set to the second-highest priority is then transmitted at the highest priority.

• WFQ. Allows different scheduling priorities to statistically multiplex data flows with different shares on the service. Each data flow has a separate FIFO queue. A link transmitting at a data rate R, all non-empty data flows N are served simultaneously according to the assigned share w, each at an average rate of R/(w1 + w2 + w3 + … +wN). If one data flow stops, the remaining data flows each receive a larger share w.

The WRED mechanism ensures that queues are not congested and high priority traffic is maintained

Service Level Agreement (SLA) Monitoring

ETX-202A is an effective tool for measuring the Service Level Agreement parameters, such as Frame Delay, Frame Delay Variance (jitter), Frame Loss and Availability.

L2CP Handling

ETX-202A can be configured to tunnel the Layer-2 control frames across the network, to peer supported protocols (OAM.ah) or to discard the L2CP frames.

Fault Propagation

The unit provides the network-to-user fault propagation mechanism on the port level. When the fault propagation is enabled, the user port shuts itself down when a link failure is detected at the network port.

Management

Setup, monitoring and diagnostics tests can be performed using one of the following methods:

Note



• Local management via ASCII terminal connected to the V.24/RS-232 DCE control port.

• Remote management via the network or user ports using Telnet SSH, Web, Secured Web (HTTPS) using ConfiguRAD, or RADview, RAD’s SNMP-based management system. ETX-202A supports the SNMP version 3 entity, providing secure access to the device by authenticating and encrypting packets transmitted over the network. ETX-202A can be managed as follows:

Remote inband management via one of the Ethernet ports using Telnet SSH, Web, Secured Web (HTTPs) or RADview, RAD’s SNMP based management system.

Local management via the last user port configured as a dedicated management port.

ConfiguRAD

ConfiguRAD is a user-friendly Web-based terminal management system serving for remote device configuration and maintenance. It is embedded into ETX-202A and provided at no extra cost. ConfiguRAD can be run from any standard Web browser.

Inband Management

ETX-202A can be managed via tagged or untagged management frames:

• When tagging is enabled, the host packets receive a VLAN tag, creating a dedicated management VLAN.

• When tagging is disabled, no traffic separation is performed and management packets can be forwarded to any user or network port.

Security

To ensure client-server communication privacy and correct user authentication, ETX-202A supports the security protocols listed below:

• RADIUS (client authentication only)

• SSL for Web-based management application

• SSH for Secure Shell communication session

• SNMPv3

Ethernet OAM

ETX-202A provides OAM to monitor and troubleshoot an Ethernet network and quickly detect failures. Two OAM types are provided:

• CFM OAM (End-to-end OAM) based on IEEE 802.1ag and Y.1731 for continuity check, non-intrusive loopback and performance management, including Frame Delay, Frame Delay Variation, Frame Loss, Availability etc

• EFM OAM (Link OAM) according to IEEE 802.3ah for remote management and fault indication, including remote loopback, dying gasp, and MIB parameters retrieval.

Appendix C provides a detailed description of the OAM functions.



Syslog Support

The syslog protocol is a client/server-type protocol, featuring a standard for forwarding log messages in an IP network. The syslog sender sends a small text message of less than 1024 bytes to the syslog receiver. Syslog messages can be sent via UDP and/or TCP in cleartext. However, although not part of the syslog protocol itself, an SSL wrapper such as Stunnel, sslio or sslwrap can be used to provide for a layer of encryption through SSL/TLS.

DHCP Client

When enabled, the DHCP client of ETX-202A requests an IP address, IP mask and default gateway from the DHCP server. In addition, ETX-202A defines a network manager with a valid IP address and subnet mask.

Statistics Collection

ETX-202A collects Ethernet performance statistics for the physical layers of the network/user ports, Ethernet flows and Flow.Cos.

Dying Gasp

ETX-202A units equipped with a single AC power supply feature a dying gasp mechanism. In case of a power outage, ETX-202A reports this failure to defined network management stations by sending out traps, thus enabling the unit to properly disconnect from the network.

Network Time Protocol

The Network Time Protocol (NTP) provides the means of synchronizing all managed elements across the network to a reliable clock source. ETX-202A supports the client side of the NTP v.3 (RFC 1305).

Diagnostic Tools

A built-in ping utility allows checking IP connectivity by pinging remote IP hosts.

The Trace Route application can quickly trace a route from ETX-202A to any other network device.

Physical loopbacks (remote/local on the port/flow level) can be closed on any of the ETX-202A ports. Layer-2 loopback with MAC address swapping enables end-to-end connectivity verification.

Network Port

The two network interfaces operate redundant to each other, either as two separate links (1:1) or as a single logical link (LAG).

• 1:1 bidirectional protection (redundancy) mode. In this mode, only one port is active at a time to carry traffic. If it fails, the second port takes over. The recovery mode (revertive or non-revertive) and the restoration time in the revertive mode can be selected according to the application requirements.

• Link aggregation (LAG) mode according to IEEE 802.3ad (without LACP). In this mode, both ports receive traffic at the same time and one port transmits. If the transmitting port fails, traffic is transmitted and received over the second port. Both network ports must be enabled.

Using Link Aggregation

The two Gigabit Ethernet ports can be operated as a single logical interface, using link aggregation in accordance with IEEE 802.3ad without LACP (Link Aggregation Control Protocol). In the virtual link group only one link transmits at a time. If a failure occurs on the transmitting link, ETX-202A switches to the standby link in the group. The flip is performed by reassigning destination ports.

With link aggregation, the two GbE ports serve as a single logical interface. The two ports must be connected to the same switch/router, as shown in Figure 1-7.

Figure 1-7. Network Link Aggregation Redundancy Mode

Using link aggregation inherently provides redundancy, because that if one of the GbE ports fails, the other can continue transferring traffic. Therefore, link aggregation per IEEE 802.3ad has inherent APS (Automatic Protection Switching) characteristics.

Failure of one the links is detected by sensing the loss of valid signals at a port, in which case the whole traffic is sent through the remaining port. The switching time is less than a second.

Link aggregation always provides revertive recovery, because that as soon as the down port returns to normal, the full bandwidth is again available.

The equipment connected to the GbE ports must use compatible switching criteria for redundancy to be available:


1-10 Functional Description ETX-202A Ver. 1.2

• For networks using Layer 2 switching: the criterion is signal loss

• For networks using Layer 3 routing: the router must support IEEE 802.3ad or other link aggregation protocol that views the aggregated link as a single logical interface.

As the two GbE ports serve as a single logical interface, the learning tables do not change as a result of the interface flip.

Using 1:1 Bidirectional Redundancy As an alternative to link aggregation, the two ETX-202A network ports of one GbE module can be configured for 1:1 bidirectional mode. With this mode, two topologies can be used:

• Connection of both GbE ports to the same switch/router, as shown in Figure 1-7.

• Connection of the GbE ports to different switch/routers, as illustrated in Figure 1-8. The main advantage of this topology is its higher availability, because each port can be routed along a different path through the network. This topology is also referred to as dual homing.

Figure 1-8. 1:1 Bidirectional Redundancy Mode (Dual Homing)

With 1:1 bidirectional redundancy mode, at any time only one of the ports is actively carrying traffic, and the other port serves as the backup port. A RAD proprietary redundancy algorithm, based on loss of GbE signal, is used to detect line failure. The protection switching (flipping) time is less than 1 second. It also depends on the network “relearning“ time or aging.

The recovery mode after a protection switching can be selected in accordance with the application requirements:

• Non-revertive mode –ETX-202A will not automatically flip back after the failed port returns to normal operation, but only when the currently used port fails, or after a manual flip command.

• Revertive mode –ETX-202A will flip back to the original port when it returns to normal operation. Flipping back can be delayed by specifying a restoration time, during which alarms are ignored. As a result, ETX-202A starts evaluating the criteria for protection switching (flipping) only after the restoration time expires, thereby ensuring that another flip cannot occur before the specified time expires.



Fault Propagation

If a network link fails, ETX-202A propagates this condition to some or all Fault-Propagation-enabled user ports as illustrated in Figure 1-9. Doing so, the user port shuts down, thus signaling the connected CPE to stop forwarding frames through this port.

Figure 1-9. Fault Propagation

Diagnostic Loopbacks

ETX-202A supports the following diagnostics loopbacks:

• Layer-1 loopback performed at the PHY of the physical ports. When the loopback is active the data forwarded to a bridge port is looped from the Tx path to the Rx path, disrupting the traffic. This loopback cannot pass through Ethernet bridges.

• Layer-2 loopback with MAC address swapping, when ETX-202A exchanges source and destination MAC addresses of the incoming packets. This loopback can be performed per VLAN (or EVC) once it passes through Ethernet bridges and does not disrupt traffic flows, which are not being tested.

ETX-202A Ver. 1.2 Configuration and Management Alternatives 3-9

3.4 Configuration and Management Alternatives

Once installed, there are no special operating procedures for ETX-202A. The unit operates automatically after it has started up. The unit’s operational status can be constantly monitored.

If required, ETX-202A can be reconfigured. ETX-202A can be managed using different ports and applications:

• Local management via an ASCII terminal connected to the RS-232 port. Usually, preliminary configuration of the system parameters is performed via ASCII terminal. Once the ETX-202A host IP parameters are set, it is possible to access it via Telnet SSH, ConfiguRAD, SSL, or SNMP for further configuration.

• Remote inband management via user or the network ports or out-of-band via the out-of-band port. Remote management via Telnet, ConfiguRAD (RAD’s Web-based application), or SNMP. Alternatively, you may manage ETX-202A via a third-party SNMP-based NMS. Refer to Chapter 6 for a trap list.

The following functions are supported by the ETX-202A management software:

• Viewing system information

• Modifying configuration and mode of operation, including setting system default values and resetting the unit

• Monitoring ETX-202A performance

• Initiating connectivity tests

• Uploading and downloading software and configuration files.

Working with Terminal

ETX-202A has a V.24/RS-232 asynchronous DCE port, designated CONTROL and terminated in a 9-pin D-type female connector. The control port continuously monitors the incoming data stream and immediately responds to any input string received through this port.

The ETX-202A control port can be configured to communicate at the following rates: 9.6, 19.2, 38.4, 57.6 or 115.2 kbps.


3-10 Configuration and Management Alternatives ETX-202A Ver. 1.2

To start a terminal control session:

1. Make sure all ETX-202A cables and connectors are properly connected.

2. Connect ETX-202A to a PC equipped with an ASCII terminal emulation application (for example, Windows HyperTerminal or Procomm).

3. Turn on the control terminal PC and set its port parameters to the following:

Bits per second: 115,200

Data bits: 8

Parity: None

Stop bits: 1

Flow control: None.

4. Set the terminal emulator to ANSI VT100 emulation (for optimal view of system menus).

5. When the unit has initialized and successfully passed the self-test, press any key to display the user name and password entry fields.



Login

To prevent unauthorized modification of the operating parameters, ETX-202A supports two access levels:

• Superuser can perform all the activities supported by the ETX-202A management facility, including defining new users.

• User’s access rights (full control or read only) are defined by the superuser. Users are not allowed to create new users.

It is recommended to change default passwords to prevent unauthorized access to the unit.

To enter as Superuser:

1. Enter su as user name and press <Enter>.

2. Enter 1234 as password and press <Enter>.

The Main menu appears.

Superuser allows you to configure all parameters of ETX-202A and to change the su and user passwords.

To enter as User:

1. Enter user as user name and press <Enter>.

2. Enter 1234 as password and press <Enter>.

The Main menu appears.

• Unnumbered menu items are inaccessible for editing.

Note

Note



Choosing Options

How to use the terminal to perform a desired activity:

• To select a menu item, type the corresponding line number and then press <Enter>. This will either …

… display a submenu or a parameter selection screen …

or …

… let you type the (free text) parameter value in the same row

or …

… toggle the current value of the corresponding parameter (relevant to ENABLE/DISABLE or ON/OFF selections).

• The type of response to be expected after selecting a menu item is indicated as follows:

> Selecting that item will display a submenu or a parameter selection screen.

... Selecting that item will let you type the desired value in the same line.

Nothing When neither symbol is displayed, selecting that item will toggle the current selection, now shown in brackets (for example, this will change ENABLE to DISABLE or vice versa).

• When a menu does not fit on one screen (because it includes many lines), it is displayed on two consecutive pages. In this case, you will see …(N) after the last line on the first page and …(P) after the last line on the second page:

While on the first page, press <N> to display the second page

While on the second page, press to return to the first page.



• When a configuration screen is organized as a table, a special set of keys is used for navigation within the table (such screens always have a ? (help) option that displays these keys). The following keys may be used for navigation within tables:

L – move to the left R – move to the right

^D – scroll down ^U – scroll up

In addition, the following shortcuts are also available:

Tab – select the next cell that may be changed

G followed by <row number>,<col number> – select a specific cell. For example, type G2,5 to select the fifth cell in the second row.

• The current value of a parameter is listed within parentheses ( ). To change a parameter value on a parameter selection screen:

Type the line number corresponding to the desired value, and then press <Enter>.

To enter a value which requires free text entry, type in the desired string and then press <Enter>. Use backspace to erase the current string.

Note that whenever applicable, the allowed range of values of a parameter is listed within square brackets [ ].

• The entry is checked after pressing <Enter>, and it is accepted only if it is valid:

If you make an error, for example, if you press a key not active on the current screen or select an invalid parameter value, an ERROR indicator appears in the right-hand corner. This indicator disappears as soon as you make a correct operation.

If you select a parameter value incompatible with the current operating state or other parameters, you will see a message that explains the error.

• When done with the current screen, press <Esc> to return to the previous screen, or press <!> to return directly to the main menu.

Ending a Terminal Configuration Session

To end the current terminal session:

• Press <&>.

After a session is ended, it is necessary to enter again a valid user name and password to start a new session.

Chapter 4

Configuration

This chapter illustrates the configuration ETX-202A screens and explains their parameters.

The menu tree of the ETX-202A management software is shown in Chapter 3.

For your convenience, parameters that are mandatory for configuration, such as IP settings of the ETX-202A host or forwarding mode, are given in the Quick Setup menu (Main menu > Configuration > Quick Setup). This menu is explained in the Quick Start Guide at the beginning of the manual, and the menu parameters are explained in the relevant sections of the configuration chapter.

4.1 Configuring ETX-202A for Management

Usually, initial configuration of the management parameters is performed via ASCII terminal. Once the ETX-202A host IP parameters are set, it is possible to access it via Telnet, ConfiguRAD or RADview for operation configuration. Perform the following steps in order to configure ETX-202A for management:

• Configuring IP Host Parameters

• Entering Device Information

• Configuring ETX-202A Communities

• Configuring SNMPv3

• Configuring the Host Encapsulation

• Configuring the Network Managers

• Controlling Management Access

• Configuring Control Port Parameters.

Configuring IP Host Parameters

ETX-202A can be managed by a network management station, located on the LAN and connected to one of the unit’s Ethernet ports. In order to establish a proper connection, it is necessary to configure the host IP address, the subnet mask and a default gateway. It is possible to enable or disable the ETX-202A DHCP client. When enabled, ETX-202A can be reached via a default IP address obtained from the DHCP server.

Chapter 4 Configuration Installation and Operation Manual

Configuring the DHCP Client

To facilitate integration of a new device into a DHCP IP network, if no IP address has been manually configured, ETX-202A requests one from the DHCP server upon booting. ETX-202A is shipped with the DHCP client set to Enable.

• To enable IP connectivity in DHCP mode, make sure that the relevant port has been made accessible under Security Definitions (Configuration>System>Management>Host>Encapsulation>Security Definitions).

• Verify that host tagging and security definitions are configured correctly.

To enable the DHCP client and acquire IP settings for the first time:

1. From the System menu, select Host.

The Host menu appears as illustrated in Figure 4-1

2. From the Host menu, select DHCP, and choose Enable.

ETX-202A starts broadcasting requests for an IP address. When the DHCP server is found, ETX-202A receives from it all necessary host IP parameters.

3. From the Host IP menu, select DHCP Status to view the current status of the ETX-202A DHCP client:

Server ID – IP address of the DHCP server

Lease expiration time – Time when the IP address lease expires

Current status – Current status of the DHCP client (locating available server, waiting for confirmation of the IP address lease, etc).

When the IP address lease is about to expire, the DHCP client automatically requests a lease extension.

Note

Note

Installation and Operation Manual Chapter 4 Configuration


To disable the DHCP client:

• From the Host menu, select DHCP Client, and choose Disable.

ETX-202A resets the host IP address to 0.0.0.0, while preserving the IP mask and default gateway values. Telnet or HTTP connections to ETX-202A are terminated. The unit can only be accessed using a previously defined default IP address. For instructions on assigning a default address, refer to the next section.

Managing IP Parameters of the ETX-202A Host

ETX-202A allows entering IP parameters manually or using parameters acquired by the DHCP server.

To define the IP parameters manually:

1. Disable the DHCP client.

ETX-202A releases the current IP address by sending the release message to the DHCP server and resets all host IP parameters to 0.0.0.0.

2. From the Host menu, perform the following:

Select IP Address to define the host IP address

Select IP Mask to define the host IP mask.

Select Default Gateway to set the default gateway IP address

Select Default IP to enter a default IP address. Configuring a default IP address is necessary if you want to preserve a Telnet or HTTP connection to ETX-202A after having disabled its DHCP client.

The default gateway must be in the same subnet as the host.

To acquire new IP settings from a DHCP server to replace previously assigned ones:

1. In the Host IP menu, set all host IP parameters (host IP, IP mask and default gateway) to 0.0.0.0.

2. Enable the DHCP client.

ETX-202A acquires IP parameters from the DHCP server.

Configuring ETX-202A at the Application Level

At the application level you can configure the following operation entities:

• QoS

• OAM

• Flows.



Configuring the Quality of Service (QoS)

The ETX-202A Quality of Service (QoS) parameters include the following profiles:

• CoS profiles

• Marking profiles

• Bandwidth profiles

• Queue profiles

• Scheduler profiles.

These profiles can be applied to the traffic flows to ensure the desired flow classification and prioritization.

Creating a CoS Profile

CoS profiles are used to convert a user priority (P-bit, ToS or DSCP) into internal priority queues (classes of service). ETX-202A has pre-defined CoS profiles:

• UserCosPbits, when the ingress traffic is prioritized according to the 802.1p requirements, user ports only.

• NetworksCosPbits, when the ingress traffic is prioritized according to the 802.1p requirements, network ports only.

• UserCosDSCP, when the ingress traffic is prioritized according to DSCP.

• UserCosTos, when the ingress traffic is prioritized according to ToS (IP Precedence).

For each profile, the user has to define the CoS mapping to map the user priority values to the internal CoS values.

The internal queues are combined into a queue profile, which can be assigned to a network or user port.

To configure the CoS mapping for the 802.1p method:

1. Navigate to Configuration > Application > QoS.

The QoS menu appears.

Transferring Software and Configuration Files

This section presents procedures for installing new software releases into the ETX-202A units and transferring configuration files.

ETX-202A stores two software versions, each of them in one of the two 1.15 MB partitions of its flash memory, which also contains a boot program. The software is stored in compressed format. The main version is decompressed and loaded into the ETX-202A RAM upon power-up. The backup software is kept for backup purposes. If the main software becomes corrupted, you can swap it with the backup. By default, ETX-202A is delivered with active software only.

New software releases are distributed as *.img files, which are downloaded to ETX-202A. When starting a download, ETX-202A erases the current backup and places the new software in the backup partition. When downloading is complete, the unit checks the integrity of the new software file. If it is correct, the backup and active files are swapped. The new software release becomes active and the former active software becomes the backup. If a failure occurs during downloading, the new version is erased. In this case, only one version is left stored in the flash memory. The backup software can be downloaded to the unit and swapped with the main software later.

Configuration files can be uploaded for storage and backup.

The management software allows file transfer over the network via TFTP. To download software files over a serial connection via XMODEM, you have to use the Boot Manager as explained in Appendix B.

To transfer files via TFTP:

1. From the Main menu, select Utilities.

The Utilities menu appears.

2. From the Utilities menu, select File Utilities.

The File Utilities menu appears.

3. From the File Utilities menu, select S/W & File Transfer using TFTP.

Running Loopbacks

ETX-202A supports two loopback types:

• Physical Layer Loopback. It runs at the PHY of the bridge ports. When the loopback is active the data forwarded to a bridge port is looped from the Tx path to the Rx path.

• Application Layer Loopback. You may run Application Layer Loopbacks on the Bridge (UNI) port or on a flow. MAC Swap loopback support exchange source and destination MAC addresses of incoming packets. The user can define the loopback direction (ingress or egress) and the type of data to be looped back. This applies to all data except for packets with management VLAN tag or only packets with a specific VLAN tag.

Appendix B

Boot Manager

This appendix provides a description of the ETX-202A boot procedure via an ASCII terminal for downloading software.

The ETX-202A software resides in two sections of the flash memory, the boot sector and the file system. The boot sector holds a boot program that calls the rest of the program from the file system.

The file system can hold two compressed copies of the ETX-202A code. One copy is called the operating application, and the other one is called the backup application respectively. The operating file is the default-executable ETX-202A code. The backup file is used whenever the operating file is absent or corrupted.

B.1 Booting ETX-202A

ETX-202A boots up automatically. After powering up, no user intervention is required, except when the user wants to access the file system to modify or update the software or the ETX-202A configuration.

Accessing the Boot Manager

The Boot Manager menu is an option that allows you to perform basic file transfer operations. These operations are all optional.

To access the Boot Manager menu:

1. Make sure that you are logged on to ETX-202A as super user.

2. Restart ETX-202A and keep the terminal application open.

3. Immediately press <Enter> several times.

ETX-202A Ver. 1.2 Transferring Software Files B-3

B.2 Transferring Software Files

New software releases are distributed as image files transferred to ETX-202A from the Boot Manager menu using the XMODEM or the TFTP protocol. Alternatively, you can download a new software release via TFTP, when the ETX-202A management software is already running (Main menu > Utilities > File Utilities).

Downloading Application Files via XMODEM

Downloading application files using the XMODEM protocol is performed from the Boot Manager menu.

To download an application file via XMODEM:

1. Enter the Boot Manager menu as explained under Accessing the Boot Manager.

2. Select Download Files or an Application by XMODEM.

ETX-202A displays the following message: Select Copy number for download ( 0 )

3. Select the backup partition by typing its number, 0 or 1.

ETX-202A responds with the following string: Please start the XMODEM download.

4. In your terminal application, set the transfer protocol to XMODEM and then send the image file to ETX-202A.

Once the downloading is complete, ETX-202A saves the image file as active partition and upgrades ETX-202A. The previously active partition reverts to the backup, and the boot sequence continues normally.

If an error occurs while downloading, the partially downloaded application is erased from the backup partition and only the active partition remains on the flash memory.

6. Select a local software release file for downloading.

7. Enter the TFTP server’s IP address.

8. Start downloading.

ETX-202A automatically erases the backup partition, which takes about 25 seconds. Once the downloading is completed, ETX-202A saves the new application as active partition. The previously active partition reverts to the backup partition.

ETX-202A Ver. 1.2 Introduction C-1

Appendix C

Operation, Administration, and Maintenance (OAM) This appendix describes the ETX-202A Ethernet OAM functionality.

C.1 Introduction

Currently ETX-202A supports pre-standard implementation of Ethernet OAM based on Y.1731 and standard implementation based on Y.1731 and IEEE P802.1ag. The pre-standard implementation is only used for performance measurements when using two RAD units working opposite each other or when working against a RAD that runs an older version of RAD’s Ethernet OAM software. This appendix describes the pre-standard implementation. The standard implementation can be found in the standards Y.1731 and IEEE P802.1ag documents.

ETX-202A has the following capabilities for providing operation, administration, and maintenance (OAM) in the packet-switched networks:

• Continuity check

• Non-intrusive loopback which is used to detect loss of bidirectional continuity

• Performance measurements (per service).

Table C-1 lists the Ethernet OAM-related terms used in the appendix.

C.2 Reference Architecture

Figure C-1 illustrates two OAM flows:

• OAM flow originating from the CPE

The CPE-to-CPE OAM flow is transferred transparently by ETX-202A and treated as data.

• OAM flow originating from the ETX-202A devices.

The ETX-202A OAM flow runs on a data flow on the same VLAN. The ETX-202A units terminate the OAM flow and can be referred as a Maintenance Entity (ME). Each device supports up to 8 such MEs. In this case, the ETX-202A units act as MEPs (Maintenance End-Points) and not as a MIP (Maintenance Intermediate Points) and all measurements are performed on the UNI_N to UNI_N segment.

Figure C-1. OAM Architecture

Handling of OAM Levels

UNI_C to UNI_N Direction

In the UNI_C to UNI_N direction ETX-202A blocks all OAM messages with OAM level greater than 2. Messages with other OAM levels are passed transparently.

Network Ingress to UNI_N Direction

All OAM messages coming from the network ingress with the ETX MAC address or with the special OAM multicast address are sent to the CPU. All other OAM messages are passed transparently to the user ports as per the respective flow definition.

C.3 OAM Entities

This section describes the OAM entities hierarchy. Figure C-2 illustrates the relationship between UNI, flow and Service Instance (COS ID), when one or more service instances belong to one flow and one or more flow belong to a UNI. From the OAM perspective, the continuity messages and defects are activated per flow, and the PM is activated per service instance.

A flow can belong only to one UNI in the same ETX-202A.

Figure C-2. UNI, Flow and Service Instance (COS ID)

Figure C-3, Figure C-4 and Figure C-5 illustrate different combinations of UNIs, flows and service instances. Each UNI contains at least one flow, which contain at least one service instance.

• In the one flow per UNI case (Figure C-3), the PM and CC are transmitted once.

Note


C-4 OAM Flows ETX-202A Ver. 1.2

Figure C-3. One Flow per UNI

• In case of multiple flows per UNI (Figure C-4), PM and CC are transmitted three times.

Figure C-4. Multiple Flows per UNI

• In case of one flow and multiple CoS (Service Instances) per UNI (Figure C-5), the PM is transmitted three times and the CC – once.

Figure C-5. One Flow and Multiple CoS (Service Instances) per UNI

C.4 OAM Flows

Figure C-6 illustrates a typical OAM traffic flow. The OAM message is transmitted from the source MEP 1 to the destination MEP 2 and the reply is transmitted back The source is also a destination for messages from the other direction.

The OAM interval is one second, so each NTU transmits one request and one reply and receive one request and one reply. Total of four messages are transmitted per second per service instance.

OAM Messages Addressing

The OAM defines two modes of addressing, unicast and multicast. Unicast addressing is used for point-to-point connections, while multicast addressing is


ETX-202A Ver. 1.2 OAM Flows C-5

used in cases where the MAC address of the destination MEP is not known. Currently ETX-202A supports point-to-point flows only.

OAM Message Association

On the receiver side the OAM frame is associated with a flow and a service.

Flow Association

When an OAM frame is associated with a flow, the following steps are performed:

• Request message reception

When a request message is received, the VLAN is extracted to find the Flow ID. The Flow ID found at the receiver is compared against the Flow ID in the frame. If the IDs are equal, further service association is made. If it is not found, the “Flow ID no match” notification is returned in the reply message.

• Reply message reception

When a reply message is received, the VLAN is extracted to find the Flow ID. The Flow ID found at the receiver is compared against the Flow ID in the frame. If the IDs are equal, further service association is made. If it is not found, the frame is discarded and connectivity alarm is issued.

Service Association

When an OAM frame is associated with a service, the following steps are performed:

• Request message reception

The class of service characteristics are extracted from the frame and must be matched to an entry in the flows <-> services table at the receiver. If they are matched, the frame is processed. If not, the service ID is returned with the “Not Found” notification.

• Reply message reception

The class of service characteristics are extracted from the frame and must be matched to an entry in the flow <-> services table at the receiver. If they are matched, the frame is processed. If not, the frame is discarded.

Ethernet Loopback (ETH-LB)

The ETH-LB can be used to verify connectivity. The ETH-LB is performed by sending a request ETH-LB message to the remote unit and expecting an ETH-LB reply message back to verify connectivity. When the insertion rate of ETH-LB messages is much slower compared to data rate between the flow points, ETH-LB is suitable to perform in-service connectivity verification and to measure round trip delays.

The message is initiated by the local device and runs periodically making it suitable for fault detection.

Unicast ETH-LB request message is sent from a MEP to a specific MEP (remote device). The DA of the request message is a unicast MAC address of destination device. Upon receipt of the request message, the MEP responds with unicast ETH-



LB reply message. The DA of the reply message is a unicast MAC address of requesting device, learned from request message.

Continuity Check (ETH-CC)

Ethernet Continuity Check (ETH-CC) can be used to detect continuity failures across flows between a given pair of edge service point on a flow. Continuity failures are caused by:

• Major failures (link failure, device failure, network path failure etc)

• Minor failures (software failure, memory corruption, incorrect configuration etc).

The ETH-CC signal is generated by one MEP. Upon receipt of the first ETH-CC signal from a sending MEP, the receiving MEP detects continuity with sending MEP and expects to receive further periodic ETH-CC signals. Once the receiving MEP stops receiving periodic ETH-CC signals from sending MEP, it declares continuity failure. The MEP that detects the continuity failure notifies the operator by sending an alarm or a trap.

OAM Procedures

This section discusses the continuity check (CC) and the performance measurement (PM) procedures.

Continuity Check Procedure

The loopback message and the ETH-CC messages are used for continuity check. In case the services are defined and PM collection is enabled, they are also used to carry PM messages. If PM collection is disabled, the messages are used for continuity check only.

If the RX CC mode of the receiver is configured to CC-based, the continuity detection is based on ETH-CC. If the mode is set to LB-based, the continuity detection is based on ETH-LB. If the mode is disabled, the continuity detection is not performed.

ETH-LB Method

The ETH-LB method includes the following elements:

• Unicast ETH-LB transmission

Unicast ETH-LB request message is transmitted by a MEP (ETX-202A) every 1 second. The transmitted Transaction Identifier is retained for at least 5 seconds after the unicast ETH-LB signal is transmitted. The Transaction Identifier must be changed for every unicast ETH-LB message, and no Transaction Identifier from the same MEP is allowed to be repeated within 1 minute.

• Unicast ETH-LB reception and reply transmission

Whenever a valid unicast ETH-LB request message is received by MEP (ETX-202A), a unicast ETH-LB reply message is generated and transmitted to the requesting MEP. Every field in the unicast ETH-LB request message is copied to the unicast ETH-LB reply message with the following exceptions:


ETX-202A Ver. 1.2 OAM Flows C-7

The source and destination MAC addresses are swapped.

The OpCode field is vendor-specific oxFE.

The Flow and MEP ID are processed as follows: if the Flow/MEP ID do not exist in the device, it changes them to No Match” otherwise they are left intact.

• Unicast ETH-LB reply receipt

When a unicast ETH-LB reply message is received by a MEP (ETX-202A) diagnostic flow termination function, it examines the TLVs returned in the unicast ETH-LB reply message. The signal is declared invalid if the TLVs do not match those sent in the corresponding unicast ETH-LB request signal, including MEP ID and Flow ID.

• Continuity declarations

Loss of Continuity and Connectivity Mismatch states are declared by the ETH-LB mechanism.

Loss of continuity declaration

After the source device sends an ETH-LB message a timer is set with a 3.52 second timeout. If the destination device does send reply within the timeout, the source enters the loss of continuity state. Upon reply from the destination, the source resets the timer to 23.5 seconds. Regarding the continuity check message, the source checks only the Flow ID with the MEP ID. When the source enters the loss of continuity state, it adds 24 to Unavailable Seconds counter. The 23.5 second period is calculated as a sliding window.

Loss of continuity state is cleared after 3.52 seconds with at least 21 reply messages from the destination. In this case the Unavailable Seconds counter decreased by 24.

Connectivity mismatch declaration

If the source Flow ID is not equal to the destination Flow ID as recorded in the reply message for 10 consecutive times, the source enters in to misconnection state.

Misconnection state is cleared after 10 consecutive reply messages with the correct flow name from the destination.

The Unavailable counter is maintained by the service according to the number of PM messages that did not receive replies. If a mismatch notification is received to the LB request, the frame is dropped and reply message is not sent. This is why the service becomes unavailable (no reply) in case of mismatch and the unavailable counter is raised.

ETH-CC Method

The ETH-CC method includes the following elements:

• ETH-CC transmission

Unicast ETH-CC request message is transmitted by a MEP (ETX-202A) every 1 second. The transmitted Transaction Identifier is retained for at least 5 seconds after the unicast ETH-CC signal is transmitted. The Transaction Identifier must be changed for every Unicast ETH-CC message, and no



Transaction Identifier from the same MEP is allowed to be repeated within 1 minute.

• Unicast ETH-CC reply receipt

When a unicast ETH-CC message is received by a MEP (ETX-202A) diagnostic flow termination function, it examines the TLVs returned in the unicast ETH-CC message, and declares the signal invalid if the TLVs do not match those sent in the corresponding exiting MEP ID and Flow ID.

• Continuity declarations

Loss of Continuity and Connectivity Mismatch states are declared by the ETH-CC mechanism.

Loss of continuity declaration

When the MEP receives the ETH-CC message a timer is set with a 3.5 seconds timeout. If the source does send another message during this period, the destination enters the loss of continuity state. Upon receipt of the ETH-CC message, the destination resets the timer to 3.5 seconds. Regarding the continuity check message, the destination check the Flow ID and the MEP ID. When the destination enters the loss of continuity state, it adds 4 to the Unavailable Seconds counter. The 3.5 second period is calculated as a sliding window.

Loss of continuity state is cleared after 3.5 seconds with at least 2 messages from the source. In this case the Unavailable Seconds counter is decreased by 4.

Connectivity mismatch declaration

If the source Flow ID is not equal to the destination Flow ID for 10 consecutive times, the destination enters in to misconnection state.

Misconnection state is cleared after 10 consecutive reply messages with the correct flow name from the source.

The Unavailable counter is maintained by the service according to the number of PM messages that did not receive replies. If a mismatch notification is received to the LB request, the frame is dropped and reply message is not sent. This is why the service becomes unavailable (no reply) in case of mismatch and the unavailable counter is raised.

Performance Measurement

ETX-202A measures performance in 15-minute intervals. It also stores performance history data for the last 24 hours (96 intervals). Table C-2 lists the PM counters supported by ETX-202A.

C.5 RMON Statistics

In addition to the regular statistics collection, ETX-202A supports proactive SLA measurements per ETX-202A port, as per RMON-based RFC 2819. The device sends reports when one of the available counters (physical layer or OAM) rise above or drop below the set thresholds within the specified sampling period of time. These reports can be sent as SNMP traps to the defined network management stations or be written to the event log.

The following counters can be monitored:

• Dropped Frames

• Undersize Frames

• Oversize Frames

• Fragmented Frames

• Jabbers

AC/DC Adapter(AD) Plug

for DC Power Supply Connection

Supplement

Ignore this supplement if the unit is AC-powered.

Certain units are equipped with a wide-range AC/DC power supply. These units are equipped with a standard AC-type 3-prong power input connector located on the unit rear panel. This power input connector can be used for both AC and DC voltage inputs.

For DC operation, a compatible straight or 90-degree AC/DC Adapter (AD) plug for attaching to your DC power supply cable is supplied with your RAD product (see Figure 1 and Figure 2).

Connect the wires of your DC power supply cable to the AD plug, according to the voltage polarity and assembly instructions provided on page 2.

Figure 1. Straight AD Plug

Figure 2. 90-Degree AD Plug

Prepare all connections to the AD plug before inserting it into the unit’s power connector.

Caution

Note

AC/DC Adapter (AD) Plug

2

To prepare the AD plug and connect it to the DC power supply cable:

1. Loosen the cover screw on the bottom of the AD plug to open it (see Figure 3).

2. Run your DC power supply cable through the removable cable guard and through the open cable clamp.

3. Place each DC wire lead into the appropriate AD plug wire terminal according to the voltage polarity mapping shown. Afterwards, tighten the terminal screws closely.

4. Fit the cable guard in its slot and then close the clamp over the cable. Tighten the clamp screws to secure the cable.

5. Reassemble the two halves of the AD plug and tighten the cover screw.

6. Connect the assembled power supply cable to the unit.

Note: You have to flip over the non-90-degree AD plug type by 180 degrees to insert it into the unit. After inserting it, verify that the blue (negative) wire is connected to the POWER and the brown (positive) wire is connected to the RETURN.

Figure 3. AD Plug Details

• Reversing the wire voltage polarity will not cause damage to the unit, but the internal protection fuse will not function.

• Always connect a ground wire to the AD plug’s chassis (frame) ground terminal. Connecting the unit without a protective ground, or interrupting the grounding (for example, by using an extension power cord without a grounding conductor) can damage the unit or the equipment connected to it!

• The AD adapter is not intended for field wiring.

To prepare and connect the power supply cable with the TB Plug:

Note: Refer to 1Figure 2 for assistance.

1. Strip the insulation of your power supply wires according to the dimensions shown.

2. Place each wire lead into the appropriate TB plug terminal according to the voltage polarity mapping shown in 2Figure 3. (If a terminal is not already open, loosen its screw.) Afterwards, tighten the three terminal screws to close them.

3. Pull a nylon cable tie (supplied) around the power supply cable to secure it firmly to the TB plug grip, passing the tie through the holes on the grip.

4. Isolate the exposed terminal screws/wire leads using a plastic sleeve or insulating tape to avoid a short-circuit.

5. Connect the assembled power supply cable to the unit by inserting the TB plug into the unit’s VDC-IN connector until it snaps into place.

Figure 2. TB Plug Assembly

Figure 3. Mapping of the Power Supply Wire Leads to the TB Plug Terminals

• Reversing the wire voltage polarity can cause damage to the unit!

• Always connect a ground wire to the TB plug’s chassis (frame) ground terminal. Connecting the unit without a protective ground, or interruption of the grounding (for example, by using an extension power cord without a grounding conductor) can cause harm to the unit or to the equipment connected to it!

Warning


3

Note: Certain TB plugs are equipped with captive screws for securing the assembled cable’s TB plug to the unit’s VDC-IN connector (C and E types only). To secure the plug, tighten the two screws on the plug into the corresponding holes on the sides of the input connector as shown in 3Figure 4.

Figure 4. TB Plug with Captive Screws (optional)

To disconnect the TB plug:

1. If the TB plug is equipped with captive screws, loosen the captive screws (see 4Figure 4).

2. If the unit’s VDC-IN connector is type B, lift the locking latch (see 5Figure 1).

3. Pull out the TB plug carefully.

Always lift the locking latch of type B connectors before disconnecting the TB plug, to avoid damaging the TB plug.
