Multilink Point-to-Point Protocol (PPP) & 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. 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.\n\n\n\n With the Cisco 4-Port Clear Channel T1/E1 HWIC with integrated channel service unit & data service unit (CSU/DSU), you can consolidate customer premises equipment (CPE). The modules support balanced & unbalanced E1 connectivity & conform to G.703 & G.704 standards for unframed & framed E1 modes. The module supports both T1 & E1 modes, selectable by software configuration.\n \n \n\n Specifications\n \n Features Internal Yes Safety EN60950LED indicators Yes Technical details Internal Yes LED indicators Yes Compatibility Cisco 2821, \n Cisco 2851, \n Cisco 3825 & 3845.
