Cisco IOS Multiservice Applications Configuration Guide
– Diplex filters installed in the downstream RF path between the cable modems and the cable
modem cards in the Cisco uBR7200 series. Diplex filters are used to convert the single,
bidirectional signals used by cable modems to the two separate unidirectional signals used by
the cable modem cards.
– RG-59 headend coaxial cable with the maximum braid available (60 percent + 40 percent braid),
double foil, and the correct connector for this cable. The center conductor must be straight and
extend 1/8 inch (3.2 mm) beyond the end of the connector. The connector should be securely
crimped to the cable.
• Complete a basic configuration of the Cisco uBR7200 series. This includes, as a minimum, the
following tasks:
– Configure a host name and password for the Cisco uBR7200 series. For more information about
how to configure a host name and password, refer to the Cisco uBR7200 Series Installation and
Configuration Guide.
– Configure the Cisco uBR7200 series to support IP. For more information about how to configure
IP, refer to the “IP Overview,” “IP Addressing and Services,” and “IP Routing Protocols”
chapters in the Cisco IOS IP and IP Routing Configuration Guide.
– Install and configure at least one port adapter to provide WAN connectivity. The
Cisco uBR7200 series supports the following port adapters: 4-port 10Base-T Ethernet, 8-port
10Base-T Ethernet, 100Base-T Fast Ethernet, ATM, and HSSI.
For information about installing and configuring port adapters, refer to the installation and
configuration guide for the port adapter(s) you are using.
• Install at least one Cisco cable modem card in the appropriate slot of Cisco uBR7200 series chassis.
For information about installing the Cisco cable modem card, refer to the Cisco uBR7200 Series
Universal Broadband Router Hardware Installation Guide.
