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.
