C 1 H A P T E R INTRODUCTION TO BACKHAUL INSTALLATIONS Chapter overview This chapter provides an overview of the Expedience system and of the system’s infrastructure components: • The base station, which comes in two forms: • The base transceiver station (BTS) • The rackmount base station (RMB) • The access provider (AP) server • The network switches The chapter provides an installation overview. It also describes things you need to consider before installing base stations.
Infrastructure overview The base station and AP server are network infrastructure components supplied by NextNet Wireless. The network access provider configures and maintains this equipment. Additional infrastructure components include switches for use at the base station cell sites, and the head-end switch. These switches are supplied by the network access provider. If desired, the network access provider can purchase the switches through NextNet Wireless.
Figure 1.2 shows 8 RMBs installed inside the base station cabinet. Figure 1.2 Rackmount base stations inside cabinet Figure 1.3 shows a base station that can be installed outdoors or indoors. Figure 1.3 Base station for indoor or outdoor installation AP server overview The AP server acts as a relay for the CPE registration events which arrive from base stations (on the management VLAN) and are forwarded to the correct ISP provisioning server (over the control VLAN).
Head-end switch, base station cell switch, and ISP switch overview The network access provider must supply switches for their network, which include the headend switch and the switches used at the base station cell site. The network access provider must also assist their ISPs when the ISPs program their switches with the proper ISP VLAN IDs. The base stations are grouped together into cells, with between 1 and 6 base stations at a cell site.
3 Install the switch onto the 19 inch rack. 4 Slide each base station into the appropriate slot in the cabinet on the rack. 5 If you are using a 5 watt base station, install the 5 watt channel specific filter. 6 Plug in the cables which include: • GPS cable • Antenna cable • Ethernet cables • Power cables • Alarm cables Also, make sure that the fuses are installed properly. 7 Plug in the power cable to the RMBs in the cabinet, make sure the power supply is working, then turn on each RMB.
Planning the installation This section describes issues you need to consider before you install the base stations, including: • Choosing locations for the base station installation • Planning for service provider equipment components • Selection antennas • Defining naming conventions for cells, sectors, and base stations and for VLANs Choosing an installation location The base station’s location at a site depends on many factors, including the site’s physical environment, the coverage pattern you want to a
BTS installation location Table 1.1 describes some of the locations you might want to consider for a BTS. Table 1.1 Advantages/disadvantages of location choices Location Advantages Disadvantages On tower, at antennas Installing at the antennas offers cost savings, due to the fact that you can use a shorter coaxial cable to connect the base stations to your cells. This also offers the ability to transmit at higher power levels, since there is lower signal loss in shorter cables.
• SNMP server • DHCP server, if desired, to supply IP addresses to base stations • AP server • Weatherproof housing for the backbone network switch, power supplies, and UPS. Also supply weatherproof housing for the TVS module, which provides lightning protection. • Coaxial cable to connect the base station to the antenna. • Tower or building structure on which to mount cell site equipment. Equipment needs of ISP As a network access provider, you provide network bandwidth to ISPs.
Designing the deployment of base stations To plan for how base stations will be deployed: 1 Determine a naming convention for base stations. 2 Using a map of the area to be covered, define the zone names that will be used. For example, an access provider can divide a metropolitan areas into North, South, East, West, and Central zones. The network access provider then assigns base stations to a specific zone by using the set system location command.

C 2 H A P T E R CONFIGURING NETWORK ARCHITECTURE Chapter overview This chapter describes a simple network topology. It provides an overview of how to configure switches at the cell site, the head end, and the ISP sites. Architecture overview The hierarchy of the network architecture uses the concept of two layers: the access layer and the backbone layer. The functions of the access layer include connecting users — which include subscribers and the ISPs — to the backbone layer.
Configuring switches This section describes configuration of the following switches: • Switch connecting base stations at the cell site • Head end switch • ISP switch Configuring the switch at the cell site At the cell site, the network access provider must program a port on the switch to be a WAN trunk to the head end switch. Configuring the head end switch WAN trunk ports on the head end switch must be configured to accept traffic from the cell sites.
Selecting links based on another rate You might want to choose a link providing another data transfer rate. The link you choose might depend on the expected and actual traffic rates for a given cell. Choosing this option means you get lower cost circuits, but you also might get lower throughput, increased response time, and so on.

C 3 H A P T E R CONFIGURING THE AP SERVER CHAPTER3 Chapter overview This chapter describes how to configure and use the access provider (AP) server. AP server overview All base stations connect to the AP server using a TCP/IP session. Using this connection, the base stations transfer incoming registration requests from CPEs to the AP server. The AP server forwards the request to the proper provisioning server for authorization.

To do so, from a command prompt on the primary AP server, type: net stop Tomcat 2 Start the secondary AP server. To do so, from a command prompt on the secondary AP server, type: net start Tomcat After the primary server is stopped, each base station automatically detects the loss of the primary connection.
C 5 H A P T E R CONFIGURING BASE STATIONS CHAPTER5 Chapter overview This chapter describes how to configure base stations.
Setting up connection methods used to configure base stations The Expedience system allows you to connect to a base station using many methods: • Terminal emulation over a serial line • Telnet • Web server • SNMP server Before you can use a particular method to connect to the base station, you must configure its connection. To configure the base station initially, you will most likely use a serial connection and a terminal emulation session.
3 To set the IP address, or range of IP addresses, of the remote computers that are allowed to use Telnet to access the base station: set telnet remote {IPaddress | IPaddress mask} where: IPaddress is the IP address of the computer that is allowed to use Telnet to access the base station. IPaddress mask is a mask for a range IP addresses that are allowed to use Telnet to access the base station.
Setting up web access This section describes how to set up your base station for web access. Note: To determine how parameters are currently configured, you can issue a “show” command for the parameter you want to check. For example, a “show web state” command will tell you if the base station already has the web server enabled. Most of the system’s default settings for parameters will help ensure your base station is ready for web access when the factory ships the base station.
Setting up SNMP access This section describes how to set up your base station for SNMP access. Note: To determine how parameters are currently configured, issue a “show” command for the parameter you want to check. For example, a “show snmp state” command will tell you if the base station already has the SNMP agent enabled. Most of the system’s default settings for parameters will help ensure your base station is ready for SNMP access when the factory ships the base station.
6 Specify the SNMP community name. A community is a logical relationship between an SNMP agent and one or more SNMP managers. The community has a name, and all members of a community have the same access privileges. To specify the community that will have read privileges: set snmp read community {name} To specify the community that will have write privileges: set snmp write community {name} For both parameters, {name} specifies the name of the community.
Setting base station configuration parameters This section describes configuration parameters to set for proper base station operation. You can use terminal emulation, Telnet, the web interface, or an SNMP session to configure the parameters on the base station.Before you can use these methods, make sure the connection is set up. For further information, refer to the section “Setting up connection methods used to configure base stations” on page 5-32 in this guide.
set airlink downlink power This parameter specifies the base station’s transmit power level. The power levels you can specify depend on the type of base station you are using: a 2 watt base station, or a 5 watt base station. 2 watt base station Specify a power value from 10 to 31. The maximum system power level is 10, which specifies +33 dBm (2 watts). The other power levels are measured in 1 dB steps from the maximum. Example: set airlink downlink power 10 Table 5.
5 watt base station Specify a power value from 6 to 31. The maximum system power level is 6, which specifies +37 dBm (5 watts) at the RF connector. The other power levels are measured in 1 dB steps from the maximum. To operate the base station at the 5 watt level, you must install a supplied channel filter. Example: set airlink downlink power 10 Table 5.2 Transmit power levels Power value Power level 6 . . 10 . . 13 . . 16 . . 23 . . 31 +37 dBm = 5 watts +33 dBm = 2.0 watts +30 dBm = 1.
Table 5.3 describes the downlink rates for various modulation methods. Table 5.3 Downlink rate based on modulation method 4-QAM Bias 0 1 2 3 4 5 16-QAM Downlink rate 1,337,358 1,719,413 2,127,308 2,294,515 2,424,466 2,530,766 Downlink rate 2,100,580 2,975,037 3,906,987 4,288,741 4,587,929 4,828,640 64-QAM Downlink rate 2,863,803 4,230,661 5,686,667 6,282,967 6,750,392 7,126,514 16-QAM lite Downlink rate 3,627,025 5,486,284 7,466,347 ------- Table 5.

During the design of the network, the access provider defines zones of coverage for the network.
set system name The parameter specifies the name of the base station. For example, the network access provider has three base station cells in the zone called North. All base stations in this zone—regardless of their cell assignment—have the same zone name: North. Using the system name, the network access provider provides a name for each base station. This system name reflects where the base station is installed in the North zone.
Setting legacy and management VLAN IDs When the base station is shipped from the factory, the identification numbers for the legacy VLAN and for the management VLAN are both set to 1. If you or your ISPs use only CPEs that run Version 2.x software code or later, you do not need to change the default id for either VLAN. However, if you have some CPEs running version 1.x code, you need to set up a legacy VLAN with an identification number different from the management VLAN ID.
5 Set the Syslog server to the address of the network management workstation set syslog server {IPaddress} where {IPaddress} is the address of the workstation that is running the Syslog application. 6 To verify the operation of Syslog, open the Syslog server, where you can view messages or create Syslog message reports.
Remote authority: setting up the provisioning server to grant CPEs network access Under remote authority the provisioning server grants CPEs network access. All requests for access are relayed to the appropriate ISP through the network access provider’s AP server. To set up remote authority: 1 Contact the appropriate ISP to make sure the provisioning server hardware and software are properly installed. 2 Add appropriate routes to the base station’s routing table.
Local authority: setting up the base station to grant CPEs network access If you establish local authority, the base station always grants CPEs network access. All CPEs are placed on the same VLAN, which is the legacy VLAN.
5 Enable the set airlink afc parameter. This parameter allows a base station to automatically frequency lock to the external pulse from the GPS, which is one pulse per second. set airlink afc enabled 6 Save changes in Flash memory by issuing the write command. 7 For changes to take effect, reboot or reset the base station’s power.

(part number 597-6025-0100). • If desired, you can use a shorter cable to connect the base station to the GPS receiver. This alternate cable is 25 ft. (part number 597-6025-0025). You can also choose the length of the daisy-chain cable that connects one base station to another base station. • The standard cable shipped in the base station installation kit is 3 ft. (part number 5976026-0003).
Mounting and grounding the base station You can mount the base station to any surface. To mount the base station to a wall, you need to use the supplied mounting brackets. If you are installing the base station on a tower, you need to use mounting plates, which you need to acquire from another equipment supplier. Mounting the base station to a wall To mount the base station to a wall: 1 Find a surface suited to base station installation.
Mounting the base station to a tower To mount the base station on a tower: 1 Mount a back board or plate to the tower. This back board or plate is custom hardware supplied by you, the service provider. Examples of material you may want to use for your back board or plate include a 1/4 inch aluminum plate, 3/4 inch green-treated plywood, or 2/12 inch green treated lumber.
Connecting the antenna to the base station This section provides tips you can use to connect the antenna to the base station. It also provides step-by-step instructions for connecting the components to each other. Antenna connection tips Use the following tips when connecting the base station to the antenna: • You connect the antenna to the base station using a coaxial cable. The size of the cable depends on the distance between the base station and the antenna.
Follow these tips when mounting the GPS: • Mount the GPS unit on a threaded pipe or pole. • The GPS mounting socket accepts a 1.0000 x 14 straight thread. It is recommended that the pole/pipe you use be 1.000 inch. • Secure the pipe or pole to the building or other support structure. • Ensure at least half of the sky is clearly visible to the unit. • Expose the unit to the southern portion of the sky. GPS satellites move generally from the southwest to the northeast.
Powering base stations This section describes tips for powering base stations, as well as the component connection sequence you need to use to properly power base stations. Powering tips • It is recommended that you use a redundant power supply for base stations. • Each base station requires 48 volts DC at 3.0 amps maximum. • The ground of the power can be either negative or positive. The 48 volt power input to the base station is floating, so either the positive or negative can be grounded.

C 7 H A P T E R INSTALLING THE RACKMOUNT BASE STATION (RMB) CHAPTER7 Chapter overview This chapter describes how to install the rackmount base station (RMB). It describes: • Installing the cabinet onto a 19 inch rack • Installing the power supply and switch • Installing the RMB into the base station cabinet • Connecting the RMBs to the cell and to cell-site components Before you begin Before you install RMBs: • It is recommended that you assign a name to the RMB.
Installation overview This section provides an overview of the tasks you will perform when installing RMBs. To install the RMBs: 1 Install the mounting brackets to the cabinet, then attach the cabinet to the rack. Note: Do not operate the system before you have securely mounted the cabinet to a standard 19" rack that can handle the weight of the total system. To calculate the weight of your system, note that the housing weighs 43 pounds, each base station weighs 18 pounds, and each filter weighs 3.
Installing the mounting bracket and attaching cabinet to the 19-inch rack Before inserting RMBs into the cabinet, attach the cabinet to the rack. To attach the cabinet to the rack: 1 Attach a mounting bracket to the left side and right side of the cabinet using the 16 supplied screws (8 per side). Figure 7.1 Cabinet mounting bracket Step 1: Attach to cabinet. Step 2: Attach to rack. 2 Attach the cabinet to the rack with the 8 supplied screws, 4 for each side.
Attaching the switch and power supply to the rack Figure 7.2 shows where the switch and power supply should be installed on the rack, in relation to the cabinet and RMBs. Figure 7.2 Location of switch and power supply in rack RMBs Switch Power supply Installing the RMBs into the cabinet To install the RMB in the cabinet: 1 Grasp the RMB by handles on each side of the RMB. 2 Slide the RMB into the cabinet, aligning the guides along the side of the RMB with the gliders inside the cabinet.
Connecting RMBs to cell (cell wiring) There are minimal wiring tasks for you to perform, as the RMB simply slides into the preexisting wiring when you place the RMB in the cabinet. The cabinet into which the RMB is installed has a pre-wired harness. This harness supplies power and Ethernet connectivity to the RMB. After you connect the antenna to the appropriate connector, the RMB also receives airlink traffic. Finally, the harness supplies an alarm capability to the RMB, as well as a GPS signal.
Figure 7.3 shows how a cell, 4 RMBs, and ancillary equipment are wired together. Figure 7.
Connecting power to the RMBs This section describes how to supply power to RMBs in the cabinet, as well as recommendations for the type of power supply to use. When choosing a power supply, keep in mind: • Each base station requires 150 watts at 48 volts. So, if your cabinet holds 8 RMBs, the power supply should provide 1250 watts, at a minimum. • The power supply you choose should use an “n + 1” configuration, so that the RMBs have a backup power source in case one of the power supply modules fails.
Figure 7.4 shows the location of the power connection on the bottom of the cabinet. Figure 7.4 Power connections on bottom of cabinet DO NOT DISCONNECT. Pre-wired power and NextNet Wireless preferred power supply NextNet Wireless preferred power supply connector 50 Amp power connector (optional, for customer-provided power supply) 30 Amp battery backup connector Table 7.1 describes the power connectors that you must use with the cabinet.
Powering tips • It is recommended that you use a redundant power supply for base stations. • Each base station requires 150 watts at 48 volts of power. • The ground of the power can be either negative or positive. The 48 volt power input to the base station is floating, so either the positive or negative can be grounded. • Power input is polarity sensitive, so be sure you connect V+ and V- properly.
Grounding the RMBs There is one grounding bar in each cabinet. Each bank of 4 RMBs are grounded to the bar. The grounding bar also contains locations for grounding terminals so that you can ground the RMBs to your building’s ground bar. Figure 7.
Turning on the RMB’s power The front panel of the RMB has a programming cable connection, 5 light-emitting diodes, and a power button. Figure 7.6 shows the front panel of the RMB. Figure 7.6 RMB LEDs DIAGNOSTICS PWR NET PPS AIR ALM POWER To turn on the RMB, press the power button. The LEDs then light. Table 7.2 describes what the base station LEDs indicate. Table 7.
Base station connectors This section describes the GPS connectors and the serial cable connectors. The serial cable is used to configure the base station with information that is unique to the carrier. GPS connectors Figure 7.7 shows the connectors that the base station supports. Figure 7.7 Connector on the serial cable used in configuring base stations A F E B G D C An RS-422 line feeds 1PPS+ and 1PPS- with the time synchronization pulse from the GPS equipment to the base station.
Power supply cable connections Table 7.3 describes the pins of the power cable used with the RMB. Table 7.
The other end of the cable has a DB9 cable connector. Figure 7.8 describes the cable’s pins. Figure 7.8 Diagnostic cable: DB9 connector pins Yellow/RXD Green/TXD Red/GND Fuses and Ethernet cable connections on cabinet Each RMB has a corresponding fuse and Ethernet cable connection on the cabinet. The RMB that occupies the lowest position in the cabinet is number 1, and the RMB that occupies the highest point in the cabinet is number 8. Figure 7.
Checking and replacing fuses The system uses a standard fuse, AG3, 5 amps, 250 volts. To remove a fuse from the cabinet: 1 Insert a flat head screw driver into the slot on the front of the gray fuse case. 2 Turn the screw driver counter-clockwise about 1/8th of a turn, until the fuse case pops out of the slot. Figure 7.10 Removing fuse from cabinet 3 The fuse slides out of the back of the case.

C 8 H A P T E R TESTING AND MANAGING THE NETWORK Chapter overview This chapter describes how to test the network before the network is used by ISPs. The chapter also provides an overview of network management tasks. Testing the setup overview This section provides an overview of the steps that help network access providers test the setup of the network before the network is rolled out. To test the network setup: 1 Install and configure the AP server, as described in this guide.
Testing the connection between the AP server and the provisioning server To make sure that the AP server and the provisioning server are communicating: 1 On the provisioning server, open the home page of the provisioning server interface. For more information about the provisioning server, refer to Chapter 2, “Working with the provisioning server” in the guide “Configuring and monitoring the ISP network.” 2 On the home page, check the Access Provider Connection group.
Fault isolation overview This section describes the fault isolation features of the network. Using SNMP server to receive and report trap information The network access provider can use an SNMP management station. This station reports all abnormal system conditions. Based on the severity of the event, the SNMP management system issues visual, audio, email and paging alerts.
Performance management overview This section describes the performance management features of the network. Using SNMP features to monitor network activity The base station runs an SNMP agent supporting MIB-II and a NextNet Wireless enterprise MIB. The SNMP agent allows a standard way of managing the Expedience system.
