Description

Cisco expansion module – 1 ports

Cisco’s PA-T3+ port adapters for the Cisco 7200, Cisco 7500, and Cisco 7400 Series routers offer high-density, highly manageable DS3 line termination. Demand for high- capacity corporate backbones, high- speed access to the global Internet, and trunking connections for service provider internetworking has led to growth in clear-channel DS3 connections that has outpaced all other types and speeds of leased lines. This growth has placed tremendous strains on the abilities of service providers and network managers to provision and manage new DS3 connections. With integrated line interface units data service units (DSUs) that allow DS3 lines to be directly terminated on a Cisco router, the Cisco PA-T3+ port adaptors simplify DS3 line management, reduce provisioning cost, and free valuable rack space.
