Feature Overview

Multipoint Headend System

The Cisco broadband fixedwireless multipoint headend system is designed to use antennas that transmit the RF signal in a portion of a complete circle, or directionally, in what is called a sector. Each headend site can be designed and configured to broadcast in a single sector, or in multiple sectors, depending on the requirements of the network.

For each sector, the components of a multipoint headend system (see Figure 1) consist of the necessary cables and:

• One Cisco uBR7200 series universal broadband router

• One wireless modem card installed in the router

• One power feed panel

• One or two antennas (second antenna for diversity reception is optional)

• One or two wireless transverters containing the RF amplifier (one for each antenna)

• One or two duplexers (one for each wireless transverter)

Feature Overview

Wireless Modem Card

The wireless modem card installs in a modem card slot of a Cisco uBR7200 series. It is configured through the router’s system console or via the CiscoView network management system. The wireless modem card provides the control and data interface to the system’s digital motherboard and the radio frequency (RF) subsystem in the wireless transverter. It also provides the up/down conversion from baseband to intermediate frequency (IF).

The wireless modem card consists of the following components:

• Digital motherboard

• IF analog board

• 10-MHz input connection for external reference clock signal (external reference clock is optional)

• 10-MHz output connection for forwarding optional external reference clock signal to another

wireless modem card

• Monitor connections for monitoring the power feed panel connections (main and diversity)

• Power feed panel connections (main and diversity)

• Light-emitting diodes (LEDs) that provide a visual indication of the state of the modem card

For further information regarding the wireless modem card, including detailed installation and configuration information, refer to the Cisco uBR7200 Series Router Multipoint Wireless Modem Card and Subsystem Installation document.

Power Feed Panel

The power feed panel serves as an interconnection device between the wireless modem card, the wireless transverter, and a –48 VDC power supply. The main purpose of this unit is to provide DC power to the system, provide control signals to the wireless transverter, and transmit and receive IF signals to and from the transverters. In addition, the unit contains circuit breakers for the DC power.

commands can be listed under any of these groups.

Cisco IOS Release 12.1(5)XM

Multipoint Wireless Support for the Cisco uBR7200 Series Universal Broadband Router

Overriding the Default Microcode Path

The wireless line card requires external microcode images in order to operate. The Cisco IOS software has a default ﬁle path where it looks to ﬁnd the microcode and the microcode version. For routers that are conﬁgured with line cards at the factory, the path and version of the microcode image in ﬂash memory matches the default setting and allows the line card to come up without any additional conﬁguration. However, you may want to override the default microcode path, for example, to upgrade your software to the latest release. Use the following steps to change the path for the microcode.

Command Purpose

Step 1 Step 2 Step 3 Step 4

Step 5

Step 6 Step 7 Step 8

Router# dir flash Router# show microcode Router# config t Router(config)# microcode cwrhe

Router(config)# end

Router# show microcode Router# microcode reload cwrhe Router# copy running-config startup-config

bundle-path

Configuration Tasks

Displays the content of the Flash memory. Displays the default path for the microcode. Enters the global configuration mode. Specifies the a new path for the headend

microcode bundle. Exits the global configurationmode and enters the

EXEC mode. Displays the specified path for the microcode. Loads the microcode onto the line card. Saves the path for the microcode so that the

microcode is loaded from the new path the next time the router is rebooted.

Configuring IF Loopback (Optional)

An IF loopback conﬁrms that the hardware is seated properly in the chassis and that the analog and signal processing portions of the wireless modem card are functioning as expected. Loopback does not test forward error corrections (FEC) and MAC-layer interface of the line card; other tests must be done for these portions of the line card. Each receive path must be tested individually when there are two antennas employed. Use the following commands to execute an IF loopback. Specifying these commands shuts down the

radio link and initiates the IF loopback.

Command Purpose

Step 1 Step 2

Step 3 Step 4 Step 5

Step 6 Step 7

Router(config-if)# shut Router(config-if)# loopback local if main 2

Router(config-if)# no shut Router(config-if)# shut Router(config-if)# loopback local if main 3

Removes the loopback commands used up to this point.

Establishes link.

If a second antenna is employed, its receive path must also be tested. Use the following commands to configure the second antenna. Issue the show running-configuration command to see the IF configuration.

Stops the interface. Configures the IF to loop the lower half of the

channel for antenna 2. Brings up the loopback mode. Stops the interface. Configures the IF to loop the upper half of the

channel for antenna 2. Brings up the loopback mode. Stops the interface. Removes the loopback commands used up to this

point. Establishes link.

Configuring RF Loopback (Optional)

An RF loopback conﬁrms that the wiring to the transverter is correct, that communication has been established from the line card to the transverter, and that the transverter is operating correctly. (It does not test the duplexer, which is the ﬁnal stage before the signal is sent to the antenna.) Also, loopback does not test forward error corrections (FEC) and MAC-layer interface of the line card; other tests must be done for these portions of the line card. Because there is only one transmit path, the path to each transverter must be tested separately. Use the following commands to conﬁgure the RF loopback.

Command Purpose

Step 1 Step 2

Step 3 Step 4 Step 5

Step 6 Step 7

Router(config-if)# shut Router(config-if)# loopback local rf main 2

Router(config-if)# no shut Router(config-if)# shut Router(config-if)# loopback local rf main 3

Configuring the Automatic Level Control (ALC)

The automatic level control (ALC) module governs the individual transmit power levels of all the subscriber units. The purpose of ALC is to ensure that the target receive power at the headend is maintained over time by taking power measurements of all the subscribers many times per second. Taking power measurements in small intervals results in better resilience to the fading environment, but it consumes more upstream bandwidth. ALC can be disabled, but this is not recommended because it results in poor upstream link performance. The current system allows only one interval setting for an entire sector. The default interval is 96 ms.

Sets the subchannel and modulation-profile assignment for the upstream channel.

Note The bandwidth of the subchannel must

match the bandwidth of the modulation-profile.

Sets the downstream transmit power to power in dBm.

Sets the target receive power in dBm for the upstream port. The usportnum field specifies the upstream port number. The target receive power must be set for each upstream port.
