1. GENERAL DESCRIPTION

1.1. Designed use

EtherTelEtherTelEtherTelEtherTel TM-78 is a converter that enables connecting independent segments of local area networks in Ethernet 10BASE-T and 100BASE-TX standard, using SDH or PDH telecommunication network, on the basis of framed signal with transmission rate of 2048 kbit/s, structure specified in guideline G.704, interface according to guideline G.703. Data transmission rate can be one of n x 64 kbit/s, where n = 1 ÷ 31. Operation in non-framed mode is also possible at full speed of 2048 kbit/s.

Each Ethernet package has a destination address field, determining the destination for transmitted data. EtherTel EtherTel EtherTel EtherTel receives the incoming package and verifies its destination address, then compares the address with source addresses collected from previous frames and decides whether the frame should be sent to a second port or not. Therefore, network segments can be isolated and network capacity can be increased. Flow control, compliant with IEEE802.3x, determines the method of sending the frames in full duplex mode so that to avoid overloading the converter.

EtherTel EtherTel EtherTel EtherTel converter also transparently transfers Ethernet frames longer than 1522 bytes, belonging to virtual networks according to IEEE 802.1Q standard, or to setting priorities IEEE 802.1p.



1.2. Sample applications

One of the simplest applications is the possibility of providing Internet access service using telecommunication network with transmission speed gradation n x 64 kbit/s. The service operator may freely switch the range, depending on the user’s requirements and capacity (Figure 1-1).

EtherTelEtherTelEtherTelEtherTel Figure 1-2: Example application II.

Figure 1-3 presents the option of applying EtherTel EtherTel EtherTel EtherTel converters in network management,

supervision, configuration or monitoring applications. Using a single 2048 kbit/s stream in SDH network, we can control devices located in remote facilities, distributed across a large area. The host is connected via the converter to SDH network. There are two EtherTel EtherTel EtherTel EtherTel converters in each remote facility, connected to local Ethernet. One of the converters receives host data via SDH network and transmits it to local area network, while the other converter transmits the local area network data via SDH to consecutive facilities. In this configuration, two converters perform the Add/Drop function for signal E1/G.703.

3. FUNCTIONAL DESCRIPTION

3.1. Rule of operation

The converter is equipped with 3 ports. Two ports are used for connecting external network segments. One port is equipped with an MDI output jack and the other has two output jacks, an MDI and an MDIX (switched transmission and reception signals cables). The Ethernet segment can only be connected in the second port to one of the MDI or MDIX jacks. Regardless of the device connected (NIC, hub, switch), ‘straight’ cable can always be used for that port. The third port is used for connecting E1/G.703 line.

Ethernet frame received from any port, located in time slots of G.704 frame in the form of digital channel n x 64 kbit/s, n from 1 to 31 and sent to PDH or SDH telecommunication network through G.703 interface. To the opposite direction of transmission, G.704 frame is received from the telecommunication network, Ethernet frame is extracted and sent to a relevant port of the switch, depending on where the connected station is located. The device filters local traffic within Ethernet network connected to switch ports and only retransmits inter-network traffic to remote network segments. Device configuration and operation status monitoring, as well as operation of the managing application with LNMP protocol is performed through RS-232 electrical interface.

The Ethernet interface serves two implementations of the physical layer, rated 10 Mbit/s and 100 Mbit/s, with an option of automatic negotiation, which ensures connection at a maximum available rate – Table 3-1. The mode of connection is signaled by LEDs on the front wall.

Table 3-1. Sequence of connection choice in automatic negotiation

Sequence Connection mode 1 100BASE-TX full-duplex 2 100BASE-TX 3 10BASE-T full-duplex 4 10BASE-T

The converter regularly reviews the stored addresses in the MAC source address table,

deleting the ones residing there for over 300 seconds.

3.2. Clock

The converter may send data to transmission direction E1/G.703 with a clock from two sources: • from internal quartz generator, frequency 2.048 MHz ±50 ppm, operating in MASTER mode • from clock retrieval systems of opposite direction of transmission E1/G.703, operating in

SLAVE mode

3.3. Diagnostic and signaling systems

The converter automatically checks the parameters of line interface E1/G.703 and Ethernet interface signal. It detects and signals the following conditions and volumes:

E1/G.703, G.704 line interface:

• loss of signal at interface input • loss of frame • excess of error rate (violation of HDB3 code) 1x10-3 and 1x10-5 in incoming signal • AIS signal receipt • receipt of alarm bit from remote device in zero slot of G.704 frame



Ethernet interface: • loss of connection • packets transmission • port configuration following automatic negotiation

Alarm conditions are signaled through: • relevant LED of E1 line interface being lit: LOS, LOF, ERR, AIS, • relevant LED of Ethernet interface not being lit: LNK/ACT

3.4. Test loops

The converter enables activation of two types of test loops: • Local analog loop marked as LOOP1 • Remote digital loop marked as LOOP2

Activation and deactivation of test loops from E1 interface is possible using:

• buttons on the front panel of the device: Figure 2-1 • dedicated application on Windows 9x/2000/NT.

The LOOP2 remote loop may only be activated when the E1 interface is configured in framed

mode, when a service channel exists between the two devices.



Use of diagnostic loops is only justified during installation of devices, for testing tract E1/G.703.

The loops may not be activated during normal operation with other Ethernet devices connected.

The use of the LOOP1 local loop is only allowed for the purpose of checking correctness of

connections of the telecommunication route using PCM transmission analyzer. It may not be switched on if EtherTel devices are connected on both ends of the telecommunication line. Figure 3-1.

The rules of using the LOOP2 remote loop are the same as for LOOP1. To use the remote loop, G.703 interfaces of the converters should be connected to line and the loop should be closed. On Figure 3-2 converter 2 activates the remote loop in converter 1.

Then it is disconnected and a PCM transmission analyzer can be connected in its place to take measurements of the route. The time between disconnecting the converter and connecting the analyzer may not exceed 10 s, as after that time the loop disconnects automatically.

3.5. Quality management

Quality management refers to surveillance of transmissoin quality in line G.703/E1 ensured by the device, and to package transmission between LAN and WAN ports.

Quality surveillance between LAN and WAN ports consists in monitoring the transmitted packages and registration of bad packages. Transmission quality assessment is the proportion of the number of bad packages to all packages transmitted in the given time.

Quality surveillance of line E1/G.703 consists in recording quality-related transmission events that can be used for assessing transmission and service quality according to G.826. The following should be used as a basis of quality assessment:

• number of errored seconds - ES • number of severely errored seconds - SES • number of errored blocks – EB • proportion of errored seconds to all seconds when the device is available – ESR [%] • proportion of severely errored seconds to all seconds when the device is available – SESR [%] • proportion of errored blocks to all blocks when the device is available – BBER [%] • number of device availability seconds - AS • number of device unavailability seconds – UAS, 10 consecutive SES change the line status to

unavailable, 10 seconds without SES restores the availability status • total number of seconds of operations from the point of switching on the device – TS

AS value = TS – UAS Table 3-3. Event table. specifies the manner of interpretation of events from the receiving

direction for 2048 kbit/s signal.

Table 3-3. Event table.

Type of event per 1 second Interpretation

1 LOS - loss of signal at input ES + SES 1 HDB3 code error ES 1 LOF – loss of frame ES + SES 1 AIS – alarm indication signal ES + SES 10-6 – error rate ES 10-3 – error rate SES 1 FAS – errors in synchronization pattern ES 28 FAS ES + SES 1 CRC-4 – control sequence ES 805 CRC-4 ES + SES

The number of events related to quality of threshold excess is counted in 15-minute and 24-

hour cycles in registries located in the device. The 15-minute logs form a stack of at least 16 logs of past periods. When all logs are full,

the contents of the oldest 15-minute cycle logs can be lost. The operator can read and set thresholds for 15-minute and 24-hour logs. Quality thresholds

for a 15-minute cycle should be set in a range from 1 to 900, with the following recommended default values: 120 for ES and 15 for SES. No threshold values are specified in standards for the 24-hour cycle. Quality thresholds for the 24 h cycle should be set within a range from 0 to 86400.

Device unavailability definitions are presented in Figure 3-3.

3.6. Event log

The converter has a function of registering the time and date of occurrence of an event with a specified criteria. The following types of events are included here:

• occurrence or loss of signal at input of the E1 line interface • synchronization or loss of synchronization of E1 connection • synchronization or loss of synchronization of E1 frame • excess or below threshold value of block error rate of 10-3 of signal received from E1 line

interface • excess or below threshold value of block error rate of 10-5 of signal received from E1 line

interface • excess or below user-defined threshold value of counts of the 15-minute ES counter (ES15) • excess or below user-defined threshold value of counts of the 24-hour ES counter (ES24) • excess or below user-defined threshold value of counts of the 15-minute SES counter

(SES15) • excess or below user-defined threshold value of counts of the 24-hour SES counter (SES24) • connection or disconnection of test loops • approval of change in device configuration • attempt at unauthorized access to device configuration system using VT-100 terminal

emulator in case of password protection

Viewing and clearing the event log, as well as defining maximum and minimum threshold values for the ES15, ES24 and SES15, SES24 counters of the E1 interface is possible using the LanWin application, described in chapter 5.

3.7. Service channels

Managing applications developed for the converter enable managing the local device, as well as the remote device using service channels. These are dedicated Windows 9x/2000/NT platform applications LanWin and VT-100 terminal emulator software, enabling only local device management.

In the case of G.703 interface, such channel can be created on any single slot of the G.704 stream with a flow capacity of 64 kbit/s. A channel may also be created on slot 0 (TS0), while it should be noted that the flow capacity of such service channel will be only 20 kbit/s. A slot for a service channel of the E1 interface can be selected from the managing application level.

In case of E1 interface configuration into non-framed mode, converters can no longer manage the remote device connected on the side of the E1 interface. This is due to their inability to select the surveillance slot.



4. INSTALLATION & OPERATION

4.1. Introduction

Proper installation and configuration of the device in accordance with guidelines contained in the following sections of this manual is required before commencement of operation.

4.2. Working conditions

The converter may work in continuous mode indoors, in conditions specified in Technical Data. It should not be exposed to direct sunlight. The device should not be placed on heat sources, although it may be put on another device of the same type or on a rack with other operating devices. In this latter case, free air circulation or forced ventilation when necessary should be provided.

4.3. Power Supply

The converter is supplied with the following voltage: 4.5 – 5.5 VAC. Supply voltage with proper polarization must be provided. The converter is supplied with 4,5÷5,5 VDC, maintaining polarization on the supply connection. Power supply should be connected to the jack with external bolted clamps. Polarity of supply voltage is described on the rear plate Figure 2-2.

Earth should be connected to the earthing clamp on the housing. The earthing wire should be of low impedance type for high frequencies.

Proper power supply is signaled with a green LED lit on the front panel of the device. A Mascot power supply unit type 5015, 230VAC/4,5VDC is recommended for supplying 230

VAC from the power network, with marked polarization cable. Grey, white or red color on one of the cores means „+”, all black core means „-”.

Optionally, ECD1-R2-48s05 type power supply by Merawex can be used, which enables supplying the converter from 48 VDC. The power supply unit can be mounted to the DIN rail or to a flat area with a velcro. The power supply unit is equipped with clamped connections. To attach a cable, insert a screwdriver in one of the openings, causing the clamps to open, then insert a cable in the other opening and remove the screwdriver. Properly fixed cable should not slip away from the connector. Polarity of the +48 V input voltage and +5 V output voltage is described on the housing. Connect „+” of the power supply unit with „+” of the converter and „-” with „ -”. The scope of delivery contains two-core cable with polarity marking for simple connection of power supply, one core being red and black, the other being black.

The manufacturer guarantees conformity with safety and electromagnetic compatibility standards for operation with such power supply units.

! The device is not provided with an integrated tripping system. Therefore, an easily available tripping system should be mounted in fixed cabling.

4.6. Clock setup

Three variants of converter operation are possible. The converters may transmit data, depending on conditions and capacity of the telecommunication network, in the following layouts:

• MASTER-MASTER • MASTER-SLAVE • SLAVE-SLAVE

The converter operates in MASTER mode when the clock source for data transmitted to the E1/G.703 interface is the clock from internal quartz generator. In SLAVE mode, clock source for data transmitted to the E1/G.703 interface is the clock retrieved from the opposite direction of transmission.

In MASTER-MASTER mode, both converters work with their own internal clocks – plesiochronous transmission. Possible work with PDH and SDH systems configured in asynchronous mode.

In MASTER-SLAVE mode, the master works with internal clock and the slave works with retrieved clock – synchronous transmission. Possible work with PDH and SDH systems configured in asynchronous mode.

In SLAVE-SLAVE mode, both converters work with retrieved clocks – synchronous transmission. This configuration is only possible if the converters are connected to SDH telecommunication network and the network operates in synchronous mode. Work with PDH systems is not possible.

4.7. Configuration of the E1 G.703 interface

The converter has the following E1 G.703 interface configuration functions: • CRC option available only in framing mode on

o switching this option on enables achieving proper integration with equipment that requires transmission of the remainder of CRC division in zero slot C1-C4 bits

o switching this option off results in setting C bits of the zero slot in ‘1’ position • Framing

o switching this option on enables proper integration with equipment operating with G.704 framed signal and allows selection of a block of slots for transmission. In addition, this option enables communication with the remote device on the side of the E1 interface.

o option off results in blocked selection of slots, surveillance slot and CRC setting. When the framing option is off, E1 stream is transmitted transparently. Therefore, data can be transmitted at full speed of 2048 kbit/s.

• Multiframe o Switching this option on enables proper integration with operating equipment that

uses the sixteenth slot for signals transmission. o In this option, the sixteenth slot may not be used for data transmission

• Choice of surveillance slot number, to be used for managing the remote device connected on the side of the E1 interface, option available only if framing is on.

6. CONVERTER SETUP WITH VT-100 TERMINAL

Converters can be configured and monitored from the level of VT-100 terminal emulator application.

6.1. Starting the setup and monitoring software

To start the monitoring software, connect the device to a terminal or a PC with terminal emulation software compliant with VT-100 installed. Then, configure the terminal or terminal emulation software (such as, for instance, TERM95 from the Norton Commander suite, or HYPERTERMINAL from Windows). The table below presents the required settings of this software, ensuring proper integration between the terminal and the TM-78.1 modem:

Parameter TERM95 HYPERTERMINAL Transmission rate 9600 bit/s 9600 bit/s Data bits 8 8 Stop bits 1 1 Flow control None None Local echo None None Terminal type VT-100 - Parity - None Font - Terminal

After switching the device on, it performs internal circuits tests. When the tests are over, the device is ready to work. You can then start working with the terminal, which you should turn on and input the start command. To confirm, press <ENTER>

You can enter this command in small or capital letters. The device recognizes the command and reports, displaying device type and its address. Then the user is asked to enter a password to access the device. If no password has been set, you can skip entering the password (press ENTER).

6.2. Description of each panel

Terminal of the TM-78.1 modem was designed for maximum convenience and ease of operation. It is built of several associated menus and panels, whose operation has been simplified to maximum.

The whole range of working with software consists in operating the ARROW KEYS, BACKSPACE, SPACE, ENTER. The user only needs to exchange data with the terminal ‘manually’ where absolutely necessary (entering and modifying the date, clock, password, device name).

After powering on, the device reports its hardware address.



6.2.1. Main menu

Figure 6-1: Login.

EMERGENCY CLEARING OF PASSWORD!!

If you forget your password, you can clear it in emergency mode. To do so, enter %kod01 instead of the password. The software will generate an eight-digit

sequence, which you should submit to LANEX technical service. An emergency password will be generated on this basis, allowing 12-hour access to the device. During this 12-hour period you can use the emergency password to clear the old password and enter a new password

The main menu is the entry screen to all other panels.

Figure 6-2: Main Menu.



6.2.2. System menu

This panel allows the user to: • modify the device name • activate a password and enter a new password (if a password was entered while starting the

terminal, you will be requested to provide it) • changing system time and date
