Cisco 4-Port Clear Channel T1/E1 High-Speed WAN
Interface Card for Cisco 2821, 2851, and 3800 Series
Integrated Services Routers

The Cisco

4-Port Clear Channel T1/E1 High-Speed WAN Interface Card provides

n x T1/E1 connectivity in a compact form factor and reduces deployment and

management costs.

As more data and voice services are enabled in branch offices, the demand for WAN bandwidth

increases accordingly. Multilink Point-to-Point Protocol (PPP) and Multilink Frame Relay enable

customers to scale their leased lines from single T1/E1 to multiples of T1/E1, adding bandwidth as

their needs increase. The Cisco 4-Port Clear Channel T1/E1 High-Speed WAN Interface Card

(HWIC) integrates four T1/E1 ports in a singlewide HWIC to facilitate n x T1/E1 connectivity in a

compact form factor (Figure 1). It also expands the scalability of T1/E1 ports on Cisco 3800 Series

Integrated Services Routers. You can use the increased port densities for small-scale WAN

aggregation in your regional offices.

With the Cisco 4-Port Clear Channel T1/E1 HWIC with integrated channel service unit and data

service unit (CSU/DSU), you can consolidate customer premises equipment (CPE). The modules

support balanced and unbalanced E1 connectivity and conform to G.703 and G.704 standards for

unframed and framed E1 modes. The module supports both T1 and E1 modes, selectable by

software configuration.
