Cisco 1 Port E3 2048Mbit/s networking card

1 Port Multichannel E3 with Integrated E3 G.703 75 ohm Interface The family of multichannel interfaces decrease cost and increase manageability of WAN links by:

- Eliminating the need for any external CSU/DSUs or multiplexers

- Providing up to 128 software configurable WAN connections per single-wide port adapter

- Supporting both clear channel T1/E1 connections and channelized T1/E1 connections on the same card

- Handling all major encapsulations including ISDN and Frame Relay

With these capabilities, the family of multichannel interfaces eliminate the need for separate interface types for separate connection types. 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 are cost-effective for all WAN connectivity.
