The Solectek family of XM Series Systems provides high capacity transmission, flexibility, features, and convenience for wireless digital communications networks. The Solectek XM Series represents a new microwave architecture that is designed to address universal applications for both PDH and SDH platforms. This advanced technology platform is designed to provide the flexibility to customers for their current and future network needs. The Solectek XM Series family is based upon a common platform to support a wide range of network interfaces and configurations. It supports links for 16/32/42/63 x E1/T1, 1/2 x 100BaseTX Ethernet, DS-3/E-3/STS-1, 1000BaseTX Ethernet, and 1/2 x STM-1/OC-3. The XM Series is spectrum and data rate scalable, enabling service providers or

organizations to trade-off system gain with spectral efficiency and channel availability for optimal network connectivity. Solectek's XM Series enables network operators (mobile and private), government and access service providers to offer a portfolio of secure, scalable wireless applications for data, video, and Voice over IP (VoIP). The XM Series includes integrated Operations, Administration, Maintenance, and Provisioning (OAM&P) functionality and design features enabling simple commissioning when the radio network is initially set up in the field at the customer's premises. Furthermore, a highlight of the system is scalability and the capability to support a ring-type architecture. This ring or consecutive point radio architecture is self-healing in the event of an outage in the link and automatically re-routes data traffic, thereby ensuring that service to the end user is not interrupted. A microwave terminal is composed of an Indoor Unit (IDU) and Outdoor Unit (ODU). The IDU is designed to be frequency independent, and the ODU is designed to be capacity independent. The IDU allows selection for multiple capacity options, modulation types, radio frequency channels and transmit output power levels to accommodate and adhere to worldwide regulatory and spectral efficiency requirements. The ODU, mounted outdoors directly to the back of the antenna, can support frequency bands from 6 to 26 GHz. The system supports 1+0 and 1+1 protection and ring topologies in a single 1 RU chassis. The modem and power supply functions are supported using easily replaceable plug-in modules. An additional feature of the XM Series is the availability of a second plug-in modem/IF module to provide repeater or east/west network configurations. The overall split mount architecture consists of a single 1RU rack mount Software with a cable connecting to an Outdoor Unit (ODU) with an external antenna. A ring topology application with the XM Series is shown in Figure 1-1 below.

Figure 1-1: Ring topology application with the split architecture XM series

1.2 Applications The following are the most common applications for the XM Series PTP links:

• Cellular base station interconnection and backhaul

• Backhaul of surveillance camera networks

• Connection of industrial/enterprise sites for voice and data

2. Installation Overview

2.1 Elements of a PTP link The following diagram illustrates the basic elements of SkyWay-LM PTP link installation.

Figure 2-1: Basic PTP link diagram

Key Notes:

• The ODU mounts to the rear of the antenna.

• The ODU + Antenna assembly is installed on a mast using the mounting kit supplied with the antenna. No separate mast mounting of the ODU is necessary.

• The antenna and ODU must have compatible mounting interfaces and waveguide styles. Caution must be exercised in procuring the correct antenna.

• The IDU is to be situated in the equipment shelter at the bottom of the tower or indoor telco/network closet. If a -48VDC power source is available, then no additional power conversion or conditioning is required. If only AC sources are available, then an AC-DC power converter is required. Solectek makes available an AC-DC converter accessory for this purpose.

• The FDD nature of the link implies that ODUs must be frequency paired to achieve successful operation. Therefore, it is critical that the correct, complementary ODU pair is identified prior to installation.

• A single coax cable run carries both data and power to the ODU. N-type (male) connectors are required on both cable ends.

2.2 Installation Outline Solectek strongly recommends that a specific order of installation is followed by the installation service crew. In general, the installation requires a 2-person tower crew (one on each side) with possible help on the ground to configure the IDU. The following summary of steps is provided as an overview only. Please be sure to read through the details provided in the following sections as referred in each step.

(1) Site Preparation

• Choose and prepare a proper antenna mounting site or structure.

• Identify indoor closet/shelter location for IDU placement. Verify location and type of power available.

(2) IDU Installation

• Locate and install the IDU in appropriate network equipment rack or any other chosen location.

• Prepare the power supply source and complete the wiring of the power supply cable to the IDU. •

WARNING: The Power to the ODU must be disconnected during cable and ODU installation.

(3) ODU/Antenna Cable Assembly

• On a benchtop, secure the ODU to the rear of the antenna.

• Prepare and pull the coax cable from the IDU to the tower location.

(4) ODU/Antenna Installation

• Hoist and mount the antenna on the tower/pole

• Perform a coarse alignment of the antenna by pointing it in the general direction of the remote site.

(5) Antenna Alignment

• Power on the IDUs on both sides of the link. ODUs are powered via the IF cable.

• Attach the voltmeter to the ODU on both sides and align antennas

(6) IDU Configuration

• Verify that the link is established from the IDU console.

• Configure the link to the desired settings (modulation, bandwidth, etc).

(7) Verification

• Optimize the antenna alignment further if necessary after the IDU configuration.

• Verify the link condition via link quality and data traffic metrics

3. ODU / Antenna Description

3.1 ODU Description The ODU converts the IF signals from the IDU to the desired carrier frequency band (6 – 26 GHz) before transmitting from the antenna. The ODU compensates for the IF cable loss and delivers a constant RF output power, depending on the modulation and frequency band used for your application.

The IF cable also supplies power and a bidirectional telemetry channel to the ODU.

3.2 ODU Ports The SkyWay-XM ODU is shown in Figure 3-1. The connectors provided are as follows:

• IDU Port – The ODU is equipped with an N-type connector (female) for

connection to the IDU. High quality, outdoor grade coax cables such as LMR 400 or LMR 240 can be used to connect the ODU to the IDU.

• RSSI Port – The RSSI port is provided for measuring RSSI voltage signals, which can be used for antenna alignment. The connector type is BNC, which comes with a protective cap attached to the enclosure. The cap must be in place when the port is not in use for antenna alignment.

• Ground Lug – This pin is used for grounding the ODU. A suitable grounding cable must be run to a common ground.

Figure 3-1: SkyWay-XM ODU

3.3 Antenna Description There are a number of qualified antenna vendors whose products are mechanically and electrically compatible with the SkyWay-LM Series ODU.

It is critical that the selected antenna is designed to interface with the SkyWay ODU, specifically:

• Connector Type - The type compatible with the SkyWay-LM Series is REMEC Connector Interface. Make sure that the antenna part number is specified as such.

• Waveguide Style – The REMEC connector type is available for both rectangular and circular waveguides. Be sure that the antenna’s waveguide style matches the ODU. For details, please contact Solectek technical support.

3.4 Cable Description The primary consideration for the outdoor interconnect cable is the distance and route between the ODU and IDU. This cable should not exceed 330 feet using Times Microwave LMR-200 cable. Guidelines are provided in Table 3-1.

Cable Type Loss (dB / 100m)

Maximum Length * 140 MHz 350 MHz

LMR-200 12.6 20.1 100m LMR-300 7.6 12.1 165m LMR-400 4.9 7.8 256m RG-214 8 13.1 153m Belden 7808 8.6 14 143m Note: Maximum length calculations do not account for connector losses

Table 3-1: Cable types and maximum lengths

3.4.1 Routing the ODU/IDU Interconnect Cable Use the following steps to properly connect the ODU and IDU:

• Select where the cable will enter the building from outside.

• Determine the length of cable required. Allow three extra feet on each end to allow for strain relief, as well as any bends and turns.

• Route the cable.

• The IDU is equipped with TNC female connector on the front of the chassis. Solectek provides pigtail cables as an option. Please contact Solectek sales for details.

• The ODU is equipped with an N-type female connector. A length of coaxial cable (such as Times Microwave Systems LMR-400, LMR-300 or LMR-200) fitted with the N-type male connectors is required to connect the ODU to the IDU. This

cable assembly may be supplied in fixed lengths with the digital radio. Bulk coaxial cable of equivalent specification may also be used, with terminating connectors applied during cable installation.

• Based on an evaluation of the cable routing path, pull the ODU-IDU Interconnect cable from one unit to the other, utilizing cable trays, ducts, or conduit as required at your installation site. Take care that the ODU-IDU Interconnect cable is not kinked or damaged in any way during installation. Be sure to protect the TNC connectors from stress, damage and contamination during installation (do not pull the cable by the connectors). If multiple ODU-IDU Interconnect cables are to be installed along the same route, the cables should all be pulled at one time. Be sure the installed cable does not have any bends that exceed the specified cable bend radius. The ODU/ IDU Interconnect cable should be adequately supported on horizontal runs and should be restrained by hangers or ties on vertical runs to reduce stress on the cable. Outside the building, support and restrain the cable as required by routing and environmental conditions (wind, ice).

• The ODU-IDU and interconnection must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires that the ODU, any mounting pole or mast and any exposed interconnect cable be grounded on the outside of the structure. The IDU must be grounded to a rack or structure ground that also has direct path to earth ground.

• The ODU must be directly connected to a ground rod or equivalent earth ground. The ODU-IDU interconnect cable should also be grounded at the ODU, where the cable enters the structure and at intermediate points if the exposed cable run is long (typically at intervals of 100 ft), with the cable manufacturer's grounding kits. Lightning protection devices used with the interconnect cable must be appropriate for the transmission of the interconnect signals (DC to 350 MHz).

• Provide a sufficient but not excessive length of cable at each end to allow easy connection to the ODU and IDU without stress or tension on the cable. Excessive cable length, especially outdoors, should be avoided to minimize signal attenuation and provide a more robust and reliable installation. If installing using bulk coaxial cable, terminate the ODU-IDU Interconnect cable at each end with a male connector (TNC if the interconnect cable is to connect directly to the IDU, N-type if a pigtail cable is used) on the IDU side and a male N-type connector on the ODU side. Use of connectors, tools and termination procedures specified by the cable manufacturer is recommended.

• Once the cable has been installed but before connection has been made to

either unit, a simple DC continuity test should be made to verify the integrity of the installed cable. A DC continuity tester or digital multimeter may be used to verify a lack of DC continuity between the cable center conductor and outer conductor, with the opposite end of the cable unconnected. With a temporary test lead or shorting adapter connected to one end of the cable, DC continuity should be verified between the center and outer conductors at the opposite end.

3.5 Grounding Description

3.5.1 Grounding the ODU

Figure 3-2: Grounding of the ODU and IDU

Use the following steps to ground the ODU (refer to Figure 3-2):

• Place the grounding rod so as to allow for the shortest possible path from the grounding cable to the ODU.

• Drive the grounding rod into the ground at least eight inches from the ground surface.

• Attach a grounding clamp to the grounding rod. You will use this clamp to attach grounding wires for both the ODU and IDU, reference Figure 3-2.

• Connect a ground lug to one end of the grounding wire.

• Remove one of the lower mounting screws of the mounting pole. Insert a screw through the grounding lug terminal and re-install it to the mounting pole.

• Attach the grounding wire to the clamp on the grounding rod. If necessary, use wire staples to secure the grounding wire to the outside wall.

• Install a grounding wire from the junction box to the grounding rod.

3.5.2 Grounding the IDU Use the following steps to ground the ODU (refer to Figure 3-2)

• The IDU should be able to be connected to a system or building electrical ground

point (rack ground or power third-wire ground) with a cable of 36" or less.

• Connect the grounding wire to either grounding point on the front panel. Use 6-32x5/16 maximum length screws (not provided) to fasten the lug of the grounding cable.

• Connect the other end of the ground to the local source of ground in an appropriate manner.

4. IDU Configuration

4.1 Physical Description The SkyWay-XM IDU is based on a modular architecture. The user can choose to upgrade or change to different functionality by replacing individual modules, not the entire IDU.

4.1.1 Front Panel Indicators with LED descriptions All models of the SkyWay-XM IDUs support a variety of front panel configurations that are dependent on the network interface and capacity configurations. Figure 4-1 provides an example of the SkyWay-XM 1+0 configuration and the associated LEDs displayed on the SKYWAY-XM front panel. The controller, standard I/O (Fast Ethernet), and modem card (narrowband) have a status LED.

Figure 4-1: Basic PTP link diagram

The modem status LED indicates the modem status as described in the following table.

LED STATUS Green Active, Locked Link Orange Standby Locked Link (1+1 Only) Flashing Green Low SNR Flashing Orange Unlocked

Table 4-1: LED Status Indicators

The controller status LED is the primary front panel indicator of alarms. An alarm is generated when a specific condition is identified and is cleared when the specified condition is no longer detected. When an alarm is posted, 1. The controller status LED turns orange for 5 seconds 2. The controller status LED turns off for 5 seconds 3. The controller status LED flashes orange the number of times specified by the first digit of the alarm code 4. The controller status LED turns off for 3 seconds 5. The controller status LED flashes orange the number of times specified by the second digit of the alarm code

Steps 2-5 are repeated for each alarm posted. The entire process is repeated as long as the alarms are still posted. For all modules, a green LED indicates normal operation while a red LED indicates a module fault. A complete list of alarms is provided in the Appendix. The alarm description is also displayed in the Graphical User Interface.

4.1.2 IDU Module Description The SkyWay-XM IDU is comprised of hardware modules. The number and type of modules is dependent on the type and required functionality. The maximum number of modules that the IDU Chassis (1U) can hold is eight. A minimum of four modules are required in a basic IDU configured for 1+0 operation. These four modules are the following (highlighted in red in Figure 4-2 below):

• Power Supply Module: -48V input

• Controller Module: (2) NMS Ethernet port, Serial port, and USB port

• Main Interface Module: Three choices are available: o Fast Ethernet – (4) FE ports, (16) T1/E1 ports, o Gigabit Ethernet – (2) GE ports, (2) T1/E1 ports, o TDM – (2) FE ports, (42) T1/E1 ports

• Modem / IF Module: choice of narrowband or wideband modem o Narrowband – supports 5-30 MHz channel bandwidth o Wideband – supports up to 7-56 MHz channel bandwidth

Fig 4-2: Fully loaded IDU with basic modules shown in red.

Optional modules include:

• Redundant Power Supply Module: Second module required for 1+1 or 2+0 operations.

• Expansion TDM Module: choice of 14 or 21 T1/E1 modules • STM Interface Module

o Optical OC-3/STM-1 Module o Electrical (Coax) STM-1 Module

• Secondary Modem / IF Module: Needed for 1+1 or 2+0 operation The modules are all inserted from the front panel of the IDU chassis. All modules are hot swappable. One of the advantages of the module-based architecture is that it minimizes both operating expenditures (OPEX) and capital expenditures (CAPEX). The modularity

allows for future upgrades via new hardware modules without a full replacement of a complete chassis. In addition, maintenance costs are minimized since individual modules can be repaired or replaced. The E1/T1 interface cards shall support up to 63 channels operating simultaneously. Mixing of E1 and T1 channels is not supported. The E1/T1 interface shall be in accordance with G.703. One or two E1/T1 channels may be used as wayside channels in other operating modes. The Fast Ethernet Main Interface Module provides up to 16xE1/T1. The TDM Main Interface Module provides up to 42xE1/T1. Additional 16xE1/T1 or 21xE1/T1 expansion capabilities are provided by separate TDM Expansion Modules. The Gigabit Ethernet Main Interface Module provides up to 2xE1/T1.

4.1.2.1 Power Supply Module

Figure 4-3: Power Supply Module with a 2-pin captive power connector.

The IDU requires an input of -48 volts dc ±10% at the front panel DC Input connector. The total required power is dependent on the option cards and protection configuration (1+0, 1+1). The IDU front panel power connector pin numbering is 1 through 2, from left to right, when facing the unit front panel. Pin 1 is the power supply return and is connected to unit chassis ground internally. Pin 2 should be supplied with a nominal -48 V dc, with respect to the unit chassis (ground). A ground-isolated supply may be used, provided it will tolerate grounding of its most positive output. The recommended power input is -44 to -52 V dc at 2 Amps minimum. It is recommended that any power supply used be able to supply a minimum of 100 W to the IDU. A mating power cable connector is supplied with the IDU. It is a 2-pin plug, 5 mm pitch, manufactured by Phoenix Contact, P/N 17 86 83 1 (connector type MSTB 2,5/2-STF). This connector has screw clamp terminals that accommodate 24 AWG to 12 AWG wire. The power cable wire should be selected to provide the appropriate current with minimal voltage drop, based on the power supply voltage and length of cable required. The recommended wire size for power cables under 10 feet in length supplying -48 Vdc is 18 AWG. The IDU supplies the ODU with all required power via the ODU/IDU Interconnect cable. The IDU does not have a power on/off switch. When DC power is connected to the SDIDU™, the digital radio powers up and is operational. There can be up to 320 mW of RF power present at the antenna port (external antenna version). The antenna should be directed safely when power is applied. A secondary Power Supply Module can be used as a redundant back-up power supply. In the case of dual modem configurations (1+1, 2+0), the secondary power supply module is required for the second Modem/IF Module operation.

4.1.2.2 Main Interface Module A Main Interface Module must be included in any IDU configuration. There are three available options for the Main Interface as detailed below. All of the options include voice and data Orderwire ports. For details on the Orderwire operation, please refer to Section 4.12. The Orderwire connector details are as follows:

4.2 Consecutive Point Architecture The consecutive point network architecture is based upon the proven SONET/ SDH ring. Telecommunications service providers traditionally use the SONET/ SDH ring architecture to implement their access networks. A typical SONET/SDH network consists of the service provider's Point of Presence (POP) site and several customer sites with fiber optic cables connecting these sites in a ring configuration (see Figure 4-11). This architecture lets providers deliver high bandwidth with high availability to their customers.

Figure 4-11: Ring Configuration.

SONET/SDH rings are inherently self-healing. Each ring has both an active path and a standby path. Network traffic normally uses the active path. Should one section of the ring fail, the network will switch to the standby path. Switchover occurs in seconds. There may be a brief delay in service, but no loss of payload, thus maintaining high levels of network availability. The consecutive point architecture implemented in the SkyWay-XM Series is based on a point-to-point-to-point topology that mimics fiber rings, with broadband wireless links replacing in-ground fiber cable. A typical consecutive point network consists of a POP and several customer sites connected using SkyWay-XM. These units are typically in a

building in an east/west configuration. Using east/west configurations, each unit installed at a customer site is logically connected to two other units via an over-the-air radio frequency (RF) link to a unit at an adjacent site. Each consecutive point network typically starts and ends at a POP. A pattern of wireless links and in-building connections is repeated at each site until all buildings in the network are connected in a ring as shown for an Ethernet network in Figure 4-12. For 2 x 1+0 and 2 x 1+1 nodes payload and NMS connections need to be jumpered between two SkyWay-XM units. For 1 x 2+0 nodes, there is no need for jumpers as there is a single SkyWay-XM. For SDH or SONET payloads, the configuration is similar but an external add/drop mux is required.

Figure 4-12: Consecutive Point Network.

4.3 Spanning Tree Protocol (STP)

Spanning Tree Protocol (STP) keeps Ethernet loops from forming in a ring architecture. Without STP, loops would flood a network with packets. STP prevents loops by creating an artificial network break. In the event of a network outage, STP automatically removes the artificial break, restoring connectivity.

4.4 1+1 Protection With two modems and two power supplies installed, the SkyWay-XM supports 1+1 protection in a single 1 RU chassis as an option for a critical link. The SKYWAY-XM contains two power supplies and two modems. The power supply, ODU, IF/ telemetry and modem are protected. The digital framing and LIUs are not. One modem is referred

to as the west modem and the other as the east modem. 1+1 protection can be run in two modes called Protected Non-Diversity and Protected Diversity.

4.4.1 Protected Non-Diversity (Hot Standby) Figure 4-13 shows operation in Protected Non-Diversity mode, also called Hot Standby. In this mode, one ODU at each location transmits to two ODUs at the other location. This mode does not require the extra bandwidth or interference protection. It provides hitless receive switching and hot standby. The SKYWAY-XM automatically switches transmit ODU upon appropriate ODU alarm or ODU interface error, minimizing transmit outage time. The SKYWAY-XM supports couplers with asymmetric attenuation. The SKYWAY-XM can be configured to automatically compensate for coupler loss during switching.

Figure 4-13: 1+1 protection in a non-diversity mode

4.4.2 Protected Diversity In Protected Diversity mode, the link between each pair of modems is the same, as shown in Figure 4-14, providing complete redundancy. This arrangement requires bandwidth for both links and non-interference between the links, but it provides hitless receive and transmit switching. The SKYWAY-XM supports both frequency and spatial diversity.

Figure 4-14: 1+1 protection in diversity modem

4.4.2.1 Frequency Diversity

In frequency diversity, two frequencies are used to achieve non-interference. The proprietary framer chooses the best, or error-free, data stream and forwards it to the Line Interface Units (LIUs).

4.4.2.2 Spatial Diversity In spatial diversity, two non-interfering paths are used. The proprietary framer chooses the best, or error-free, data stream and forwards it to the Line Interface Units (LIUs).

4.4.2.2.1 Single Transmitter Protected Non-Diversity, or Hot Standby, is also referred to as Single Transmitter Spatial Diversity.

4.4.2.2.2 Dual Transmitter When using Dual Transmitter Spatial Diversity, two active transmitters are physically isolated to avoid crosstalk.

4.5 1+1 Multi-hop Repeater Setup

The SkyWay-XM supports a 1 + 1 multi-hop repeater configuration with drop/insert capability as shown in Figure 4-15. This configuration provides individual 1 + 1 link protection as well as the full-scale protection inherent in the consecutive point architecture. At each location within the network, data may be dropped or inserted. Front panel connections for drop/insert capability are shown in Figure 4-16. In this configuration each SKYWAY-XM contains two power supplies and two modems.

Figure 4-15: Multi-hop Repeater Configuration

Figure 4-16: Front Panel Connection for 1+1 multi-hop repeater configuration

4.6 100 Mbps Fast Ethernet

Scalable Ethernet data rates up to 100 Mbps can be achieved with the Main Interface Modules. Higher data rates may be achieved with using the 155FE capability.

4.6.1 155Mbps Fast Ethernet Ethernet payload rates over 100 Mbps (such as 155 Mbps) may be achieved on a Fast Ethernet SKYWAY-XM by utilizing both 100Base-TX front panel payload ports. In this configuration, two Ethernet channels are provisioned in the payload frame. The max traffic rate for each Ethernet channel to the framer is defined in the modes file. A user is not permitted to use these modes in a 2+0 configuration.

4.6.1.1 Two Network Operation This mode allows the operator to provide access to two separate Fast Ethernet users, and guarantee the throughput level for each. Different rates for each port are supported, as configured in the modes file. In this mode, each channel operates as a single channel would in a single port mode.

Figure 4-17: Two Network Operation

4.6.1.2 Single Network Operation This configuration is discussed with an external router in mind. This configuration is really an extension of the mode described above. There are no changes in the programming or operation of the SkyWay-XM. This mode allows a user to transmit data from a single network at a rate greater than 100 Mbps. The external router is required to handle the management of the trunk. The router must ensure that the same MAC address is not delivered to both front panel ports.

Figure 4-18: Single Network Operation

4.7 Gigabit Ethernet (1000 Mbps)

Scalable Ethernet data rates up to 300 Mbps can be achieved with a Gigabit Ethernet scalable SKYWAY-XM (see Table 4-2). Data rates up to 155 Mbps are available with the Standard Modem/IF module and data rates up to 300 Mbps are available with the Wideband Modem I/F module. The SKYWAY-XM may be configured to aggregate Ethernet bandwidth across two or four links when operating as 2+0 or 4+0, allowing for a total throughput of up to 600 Mbps or 1000 Mbps, respectively. Bandwidth 30 MHz 40 MHz 50 MHz 56 MHz

QPSK 30 Mbps 45 Mbps 55 Mbps 60 Mbps 16QAM 80 Mbps 100 Mbps 130 Mbps 160 Mbps 32QAM 100 Mbps 130 Mbps 160 Mbps 200 Mbps 64QAM 125 Mbps 160 Mbps 200 Mbps 250 Mbps 128QAM 150 Mbps 200 Mbps 250 Mbps 300 Mbps

Table 4-2: Throughput vs. Bandwidth – shown in full duplex numbers. For aggregate throughput, double the numbers in the table.

4.7.1 GigE Port Based VLAN

The Gigabit Ethernet Port Based VLAN configures the SKYWAY-XM to provide two independent Gigabit Ethernet networks, with aggregate data rate up to 300Mbps. In this mode the Gigabit Master IO module ports 1 and 2 are allocated to Network #1 and ports 3 and 4 are allocated to Network #2 (see Figure 4-19). The SFP port may be assigned to either Network #1 or #2. Each network will be allocated a guaranteed bandwidth, which is configured as part of the modes file. This capability is only available when operating as 1+0 or 1+1 and is not available when operating as 2+0.

Figure 4-19: GigE Port VLAN Configuration

4.8 Ethernet Quality of Service (QoS)

The SKYWAY-XM provides for Ethernet Quality of Server (QoS) configuration. Incoming packets to the SKYWAY-XM are assigned to a weighted priority queue based on one or more of the following criteria: Incoming Port: packets are assigned to a priority queue based upon the port the packet arrived on. 802.1Q VLAN Tag Priority: packets are assigned to a priority queue based upon the priority tag field in the VLAN TAG. IPv4 TOS: packets are assigned to a priority queue based upon the TOS field in the IPv4 header. DiffServ: packets are assigned to a priority queue based upon the value of the DS field of the IPv4 header.

Figure 4-20: Ethernet QoS Priority Queues

4.9 GigE Link Aggregation Setup 4.9.1 2+0 East/East Configuration The SKYWAY-XM is capable of aggregating link bandwidth in 2+0 mode to achieve up to 600 Mbps Ethernet throughput when used with the Wideband Modem/IF modules in 56MHz with 128-QAM capable ODUs. The 2+0 East/East configuration allows for the doubling of the throughputs. When configured for 2+0 East/East, the SKYWAY-XM balances the traffic between the two links based upon the source and destination MAC addresses of the Ethernet packets. Sufficient diversity of MAC addresses is required to achieve full utilization of the 2+0 East/East configuration. In the event of a link failure, throughput will only be reduced by one-half, and traffic on the failed link will be automatically re-routed to the remaining link.

4.9.2 4+0 East/East Configuration In addition to aggregating two links, the SKYWAY-XM is capable of pairing with another SKYWAY-XM to aggregate a total of four links to achieve a maximum throughput of 1000 Mbps when used with Wideband Modem/IF modules in 50MHz with 128-QAM capable ODUs. As with 2+0 East/East, the SKYWAY-XM balances the traffic between the four links based upon the source and destination MAC addresses of the Ethernet packets.

Sufficient diversity of MAC addresses is required to achieve full-utilization of the 4+0 East/East configuration.

In the event of a link failure, throughput will only be reduced by one-quarter, and traffic on the failed link will be automatically re-routed to the remaining links.

Figure 4-21: 4+0 East/East Configuration

4.10 Crosspoint Switch

The SKYWAY-XM crosspoint switch provides any-to-any E1/T1 routing between front panel ports and RF links, as shown in Figure 4-22. Flexible channel mapping allows selection from predefined routings or custom routing. Custom routings are uploaded to the SKYWAY-XM via FTP. Two examples of the crosspoint capability are to use the crosspoint switch to configure a repeater or an add/drop mux. These examples are shown in Figure 4-23. In the repeater example, the Crosspoint Switch is used as a passthrough to send E1/T1s from the east modem to the west modem. In the add/drop example, the crosspoint switch connects E1/T1s from the modems to the front-panel ports.

Figure 4-22: Crosspoint switch

Crosspoint switch allows access for add/drop.

4.11 STM-1 Specifications

The SKYWAY-XM meets G.703, G.957 (S-1.1), G.825 for the STM-1/OC-3 signals passed across the RF link. Performance monitoring is not provided as the SKYWAY-XM does not act as a regenerator. The SKYWAY-XM does not support add/drop MUX (ADM) capability. The SKYWAY-XM does support terminal MUX capability.

4.12 Voice Orderwire

The Voice Orderwire provides a PTP connection via a PTT handset and buzzer. Point-to-point calls, where the call button rings the link partner SkyWay-XM, are supported on all I/O module versions. "Party-line" calls, where the call button rings all nodes, is supported on the Gigabit Main Interface Module and 42 x E1/T1 TDM Main Interface Module.

4.13 Power Management

RF power management is a radio design feature that controls the power level (typically expressed in dBm) of the RF signal received from a transmitter by a receiver. The traditional goal of power management is to ensure that the RF signal at a receiver is strong enough to maintain the radio link under changing weather and link conditions. The SKYWAY-XM employs spectrally efficient shaped Quadrature Amplitude Modulation (QAM). This waveform is not a constant envelope waveform. Therefore, the average power and peak power are different. The difference in peak and average power depends on the constellation type and shaping factor, where spectral efficiency such as more constellation points or lower shaping factor leading to peak powers higher than average powers. The peak power is typically 5-7 dB greater than the average power in the SkyWay-XM, and never exceeds 7 dB. Regulatory requirements are usually based on peak EIRP which is based on peak power and antenna gain. Traditional power management techniques such as Constant Transmit Power Control (CTPC) and Automatic Transmit Power Control (ATPC) transmit at a high power level to overcome the effects of fading and interference. However, these techniques continue to operate at a higher power level than needed to maintain the link in clear weather. Because transmit power remains high when the weather clears, the level of system interference increases.

Radios operating at high transmit power will interfere with other radios, even if the interfering source is miles away from the victim. High interference levels can degrade signal quality to the point that wireless radio links become unreliable and network availability suffers. The traditional solution to system interference is to increase the distance between radios. However, the resulting sparse deployment model is inappropriate for metropolitan areas. In response to the need for a high-density deployment model the SkyWay-XM uses a unique power control technique called Adaptive TPC. Adaptive TPC enables SkyWay-XM to transmit at the minimum power level necessary to maintain a link regardless of the prevailing weather and interference conditions. The SkyWay-XM is designed and manufactured to not exceed the maximum power allowed. The purpose of power management is to minimize transmit power level when lower power levels are sufficient. Solectek’s Adaptive TPC also extends the concept of power management by controlling not only the power (dBm) of the RF signal, but its quality (signal-to-noise ratio) as well. In contrast to normal ATPC, the Adaptive TPC technique dynamically adjusts the output power based on both the actual strength and quality of the signal. Networked SkyWay-XM constantly monitor receive power and maintain 10-12 BER performance under varying interference and climate conditions. Each SkyWay-XM can detect when there is a degradation in the received signal level of quality and adjust the transmit power level of the far-end SkyWay-XM to correct for it.

Adaptive TPC provides maximum power in periods of heavy interference and fading and

minimum power when conditions are clear. Minimal transmit power reduces potential for co-channel and adjacent channel interference with other RF devices in the service area, thereby ensuring maximum frequency re-use. The resulting benefit is that operators are able to deploy more SkyWay-XM in a smaller area.

4.14 SKYWAY-XM Network Management All of the SkyWay-XM parameters are accessible in three ways: 1. Using a standard web-browser via HTTP to access the built in web server. 2. Via SNMP using the fully featured MIB, allowing for automation of data collection and network management. 3. Via a command line client accessible from a terminal client connected to the serial port, or telnet over the NMS Ethernet.

4.14.1 IP Address Each SKYWAY-XM is configured independently for network parameters such as IP address, subnet, and gateway. However, the SKYWAY-XM also supports acting as a DHCP client, in which case the IP address can be assigned to the SKYWAY-XM using a DHCP server. A specific IP address may be associated with a particular SKYWAY-XM

by configuring the DHCP server to serve IP addresses based upon the SKYWAY-XM Ethernet MAC address.

4.14.2 Network The SKYWAY-XM uses an "Out-of-Band" NMS network which is separated from the payload Ethernet network. Each SKYWAY-XM contains a managed Layer 2 Ethernet switch that supports Spanning-Tree Protocol (STP) for managing NMS traffic. This allows the SKYWAY-XM to be configured in a protected ring configuration where the STP will prevent an Ethernet loop in the ring. This will also allow the ring to reconfigure in the event of an outage. The SKYWAY-XM acts as a network bridge via the Ethernet switch and STP. The SKYWAY-XM supports a 4096 entry LAN table with an aging time of 300ms on both NMS and payload. The SKYWAY-XM does not currently support NMS routing capability.

4.14.3 NMS Network Operational Principles The SKYWAY-XM does not provide routing capability. Therefore, all SkyWay-XM units must be on the same subnet as the PC being used to access the SkyWay-XM units. If the SkyWay-XM units and/or the PC are on different subnets, a router must be used, with the gateway addresses set appropriately. Figure 2-21 shows the PC and both SkyWay-XM units in the same subnet.

4.14.4 Third Party Management Software Support The SKYWAY-XM supports SNMPv1, SNMPv2, and SNMPv3 protocols for use with third party network management software. The SNMP agent will send SNMP traps to specified IP addresses when an alarm is set or cleared. Information contained in the trap includes:

• IP address

• System uptime • System time

• Alarm name

• Alarm set/clear detail

The SKYWAY-XM may also be managed via HTTP, TELNET, and SSH protocols.

4.15 System Loopbacks The SKYWAY-XM provides system loopbacks as a means for test and verification of a unit, link, and/or network. A variety of loopback points, including LIU selection, are available, Loopback points and duration are easily selected through the Graphical User Interface. Loopback duration is also selectable.

5. Connecting to the PC/Network

5.1 Connecting the IDU to PC and Power Source

Perform the following steps to ensure the IDU is powered up and connected to you PC:

• To connect to the IDUDC power connector (located on the left front IDU panel), an IDU power cable is required. A mating power cable connector (Phoenix Contact P/N 17 86 83 1) is provided with the IDU for construction of this cable. This connector has screw clamp terminals that accommodate 24 AWG to 12 AWG wire. The recommended wire size for construction of power cables under 10 feet in length, supplying -48V dc, is 16 AWG. The opposite end of the IDU power cable should have a termination appropriate for the power supply being used. The IDU power cable should be of sufficient length to avoid tension in the cable and provide a service loop for connection, but not be of excessive length. Stranded wire should be used over a solid conductor to reduce tension on the IDUDC Power connector. Using the supplied power cable connector, pin 2 (labeled -V) should be connected to the power supply terminal supplying -48V dc, while pin 1 (labeled RET) should be connected to the power supply return. Refer to Figure 5-1.

• Use of a power supply with an inappropriate ground reference may cause

damage to the IDU and/or the supply. The IDU is designed to operate normally with a reversed polarity with a floating power-supply. If the power-supply is ground referenced (i.e. not floating), then two problems can occur if the ground reference is connected to the -48V input:

o If the IDU is properly grounded, then a power-supply short will occur. Damage to the rest of the IDU is unlikely, but the IDU’s internal power supply module could be damaged. This would require replacement of the Power Supply Module.

o If the IDU is not properly grounded, however, and the ODU is grounded, then a short or high-current path is likely. The high current path scenario could affect components on the Modem/IF Module.

Figure 5-1: IDU DC Power Cable Connector.

• Connect the IDU power cable to the -48V dc power supply, and place the voltmeter probes on the unconnected IDU end of the power cable, with the positive voltmeter probe on pin 2 (-V) of the cable connector and the negative probe on pin 1(RET). The connector terminal screw heads may be used as convenient monitor points. Refer to Figure 5-1.

• Turn on the -48V dc supply. Verify that the digital voltmeter reads between -44V dc and -52V dc when monitoring the cable points specified above. Adjust the power supply output voltage and/or change the connections at the power supply to achieve this reading.

• Turn the -48V dc supply off. • Plug the IDU power cable into the IDU front panel DC Power connector (DC

Input). Place the voltmeter probes on the cable connector terminal screw heads as per Step 2 above (Refer to Figure 5-1). Note that the IDU does not have a power on/off switch. When DC power is connected, the digital radio powers up and is operational. There can be up to 320 mW of RF power present at the antenna port. The antenna should be directed safely when power is applied.

• Turn on the -48V dc power supply, and verify that the reading on the digital voltmeter is as specified in the step above.

• Connect the IDU to the laptop computer, using a Cat-5 Ethernet cable or connect the IDU to a computer network, using a Cat-5 Ethernet cable. Connect the Ethernet cable to the NMS 1 or 2 connector on the IDU front panel. Refer to Figure 5-2 for the IDU front panel connections.

Figure 5-2: NMS Connections

5.2 IDU Configuration

Although configuration of the IDU does not require a connection to the ODU, it is recommended that the ODU and IDU are connected prior to configuring the IDU. Each IDU has a Graphical User Interface (GUI) installed that can be accessed through a computer connection. The GUI is described in detail in the User Interface Guide. The section below describes how to get started configuring the IDU via the GUI.

5.2.1 Materials Required The following items are needed to configure an IDU:

1. Power supply (-48V DC @ 2 Amps) OR optional AC/DC power supply and power cable. (A Phoenix Contact P/N 17 86 83 1 connector is provided).

2. Digital voltmeter with test leads. 3. IDU Serial Cable (optional) 4. Computer with networking capability, consisting of either:

a. Laptop computer with Windows 98/2000/XP operating system, an Ethernet card with any necessary adapters and a Cat-5 Ethernet regular or crossover cable OR

b. Networked computer with Windows 98/2000/XP operating system and an additional Ethernet cable providing access to the network.

5. Web Browser program with Java environment installed 6. Site engineering folder with site drawings, or equivalent IDU configuration

information

5.2.2 IDU Configuration Process

Using the site attributes identified in the site assessment or equivalent configuration information, configure each IDU by completing the following procedures:

• Setting the IDU IP Address and Network Parameters

• Configuring the IDU

• Setting the IDU Device Information

5.2.2.1 Setting the IDU IP Address

To manage the IDU remotely, the IP address of the radio must be set. Set the IDU IP address to the factory default or a known value. Use a web browser to access the IDUGUI and set the IP address as described below in section 5.2.2.1.1. If the IP address is unknown, a hyperterminal connection via a serial cable can be used.

5.2.2.1.1 Using the GUI to set the IP address Use the following steps:

1. The IDU should be accessible from your PC. A network 'ping' can be done to verify connectivity to the IDU.

Press the A-key to navigate to Network Configuration. 9. Press the A-key to navigate to General. 10. Press the A-key to navigate to IP Address. 11. Enter the new IP address and press the D-Key to update. If the IP address has

been entered correctly enter Y when prompted. 12. If necessary, use the same menus to set the IP Netmask and IP Gateway. 13. Close the hyperterminal connection.

5.2.2.2 Configuring the IDU

Use the GUI to configure the IDU as follows:

1. To start the GUI, open a web browser and use the IDU IP address (192.168.0.1) as the URL and log in (username and password provided in Table 3-2).

2. Use the frame on the left side of the window to navigate to "Radio Link." 3. Select the subcategory "Link Configuration." 4. Select the operating mode. If the IDU has one modem installed and is connected

to one ODU, select standard. If the IDU has two modems installed and is connected to two ODUs, select 1+1 diversity or 1+1 non-diversity for a protected link (as described in Section 2.9) or east-west for a 2+0 ring configuration (as described in Section 2.7).

5. Follow the wizard located here to enter the rest of the required settings.

5.2.2.3 Configuring the IDU Site Attributes

Use the GUI to enter device information as follows:

1. In the navigation menu, select Administration, then Device Information, and then Device Names.

2. Enter the Owner, Contact, Description, and Location. These values are not required for operation, but will help keep a system organized.

5.2.2.4 Power on Reset to Factory Defaults

The IDU may be reset to factory defaults during power up. A power on reset affects the IP address and the user logins/passwords. To perform a power on reset:

1. Power on the IDU. 2. During bootup, the IDU will flash the controller-card LED alternating red/green for

five seconds. 3. Make sure the call button is not active at the start of this five second period. 4. While the LED is flashing, press the call button. Release the call button within

one second after the LED stops flashing.

5.2.3 Default Username and Password The following table shows default log-in information for all levels of access.

User Level User Name Password Monitor monitor monitor Operator operator col1ma Administrator administrator d1scovery Integrator integrator p1nacate

5.3 Servicing the IDU At times, it may be necessary to service the IDU. This may include installing, removing, or replacing an IDU module. There may be up to 8 modules installed in a single IDU chassis. The basic procedure for removing and installing a module is common to all the modules, with slight variations for the Power Supply Module, Controller Module, and Mini IO Module. These basic procedures are described below. Variations are described in sub-items beneath each step.

5.3.1 Removing a Module

1. Modules are static sensitive and should only be handled in an ESD-safe environment. When packaging modules for shipment or storage, place in an ESD bag.

2. Remove front panel connections to the module. 3. Remove the two thumbscrews on either side of the module. Figure 5-4 shows the

locations of these thumb screws. a. The thumbscrew for the Standard IO Module is located on the right side

of the Mini IO Module slot. b. If a Mini IO module is installed and the Standard IO Module is to be

removed, both modules will be removed as one unit. c. When removing only the Mini IO card, remove the corner screw indicated

in Figure 5-4 and one thumb screw.

Figure 5-4: Locations of thumb screws and corner screws.

4. Thread thumbscrew(s) into hole(s) shown in Figure 5-4. Remove the module by

grasping the thumbscrew(s) and pulling module straight out of the IDU. Both thumbscrews should be used for all modules except the Power Supply and the Mini IO Modules.

a. The Power Supply and Mini IO Modules have only one threaded hole each.

b. When removing the Standard IO Module, the ground lug indicated in Figure 5-4 is used as the second threaded hole. If the IDU is to remain powered on and the ground lug is being used to ground the unit, first move the ground connection to the ground lug located on the Controller Module.

The IDU retains its current configuration when a module is removed, unless that module is the Controller Module. In which case, the IP addresses will need to be reprogrammed.

5.2.4 Installing a Module

1. Modules are static sensitive and should only be handled in an ESD-safe environment. When packaging modules for shipment or storage, place in an ESD bag.

2. Line up the module board with the guides in the chassis and slide the module into the IDU. Figure 5-5 shows a photo of the guides. As the module face plate comes flush with the face of the IDU, connectors on the back of the module will engage with the IDU backplane. It is possible to encounter interference from adjacent module front panels. If this occurs, loosen the thumbscrews holding the neighboring panels and shift them as necessary to ensure fit.

a. The Mini IO Module only has one guide on the right side. Take care to insert the Mini IO module carefully and correctly engage the rear connector with its mate on the Standard IO Module.

VLAN support VLAN tagged packets are passed through without modification. Port based VLANs are supported, but not user-configurable as they are used to implement 155FE and Port-based VLAN modes. The IDU uses VLAN TAG Priority (802.1Q-203 Section 9 Tagged Frame Format) for QoS.

Operation Full duplex / Half Duplex / Auto sensing

Auto Sensing and manual configuration

Support for routing Support for IP based routing is not provided. Quality of Service (QoS)

QoS is implemented using weighted priority queues. Incoming packets are assigned to a priority queue based on one or more of the following criteria:

• Incoming Port: port based priority allows assignment to a priority queue based upon the port the packet arrived on

• 802.1Q VLAN Tag Priority: packets are assigned to a priority queue based upon the priority tag field in the VLAG TAG

• IPv4 TOS (Fast Ethernet Main Interface Module only): packets are assigned to a priority queue based upon the TOS field in the IPv4 header

• DiffServ (TDM Main Interface Module only): packets are assigned to a priority queue based upon the value of the DS field of the IPv4 header (the DS field is the redefined IPv4 TOS field)

Priority Queues (Fast Ethernet Main Interface Module): 2 Priority Queues (TDM Main Interface Module): 4 Note: The weighted ratios are fixed for 802.1Q VLAN TAG priority and for IPv4 TOS priority even though they are selectable via Web GUI. The Low priority queue flows may be starved under some traffic conditions (Fast Ethernet Main Interface Module only).

Flow Control Flow control is supported in both full-duplex and half-duplex. Full-Duplex is implemented with respect for PAUSE packets as well as generation of PAUSE packets. Half-Duplex is implemented with back-pressure.
