Feature Overview

Multipoint Headend Components

Router

The Cisco uBR7200 series are designed for two-way transmission of digital data using either coaxial cable or broadband fixed wireless signals. These routers support IP routing with a wide variety of protocols and any combination of Ethernet, Fast Ethernet, High-Speed Serial Interface (HSSI), serial, and Asynchronous Transfer Mode (ATM) media. Network interfaces reside on port adapters that provide the connection between the router and external networks. Cable or wireless interfaces reside on modem cards and provide the connection to cable or wireless networks.

Other features include:

•Online insertion and removal (OIR)—Add, replace, or remove a port adapter and modem cards without interrupting the system or entering any console commands

•Downloadable software—Load new images into Flash memory remotely, without having to physically access the router

For further information regarding the Cisco uBR7200 series, including detailed installation and configuration instructions, refer to the Cisco uBR7200 Series Universal Broadband Router Installation and Configuration Guide.

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.
