Multichannel T3 Port Adapter for Cisco 7000 Series

Product Overview
The Cisco
®
1-Port Multichannel Port Adapter for the Cisco 7200 Series Routers (Cisco 7201 and
7301 Routers), Cisco 7304, Cisco 7500 and Cisco 7600 Routers decreases cost and increases
manageability of WAN links by eliminating the need for any external channel service units
(CSUs)/digital service units (DSUs) or multiplexers while providing up to 128 software-configurable
WAN connections per single-wide port adapter. It supports both full-rate T1 connections and
channelized T1 connections on the same card as well as handling all major encapsulations,
including ISDN and Frame Relay.
With these capabilities, the family of multichannel interfaces eliminates the need for separate
interface types for separate connection types. At a cost per T1 port less than that of a standard
serial port with external CSU/DSU, the multichannel interface family is cost effective for all WAN
connectivity.

Key Features
The Cisco 1-Port Multichannel Port Adapter supports physical connectivity to T3 lines, E3 lines, T1
lines, and E1 lines. For direct termination to T3 lines, the Cisco multichannel T3 card supports 28
T1 lines multiplexed onto a single DS3 (DSX-3 level) interface. The 128 channels of this
multichannel port adapter can be allocated among clear channel T1 links, NxDS0 links, or ISDN
PRI links. For a single, full-rate T1 connection, only one of the 128 channels is consumed. For
each NxDS0 connection, a single channel is consumed. In channelized T1 mode, multiple NxDS0
connections can be supported on a single T1. Fractional T1 mode is also supported where NxDS0
of bandwidth consumes an entire T1 link. Each T1 used as ISDN Primary Rate Interface (PRI)
consumes 24 channels, one per B channel and one for the D channel.
