.

The family of multichannel interfaces for the Cisco 7200 and

Cisco 7500 Series routers reduces cost and enhances

manageability of WAN links by:

• Eliminating the need for any external channel service

units/data service units CSU/DSUs)) or multiplexers

• Providing up to 128 software-configurable WAN connections

per single-wide port adapter

• Supporting channel bandwidth from 64kbps, nx64 kbps, to full

T1 or E1.

• Handling all major encapsulations, including Integrated

Services Digital Network (ISDN) and Frame Relay

With these capabilities, the family of multichannel port adapters

eliminates the need for separate interface types for separate

connection requirements. At a cost per T1/E1 port less than that

of a standard serial port with external CSU/DSU, Cisco’s family

of multichannel interfaces is cost-effective for all WAN

connectivity.

Cisco’s multichannel interface family supports multiple connection types, including bundled (N x T1/E1) links using Multilink PPP.
