Cisco SPA-4XCT3/DS0 network interface processor

The combination of channelized and clear channel T3 functions makes the Cisco® 2- and 4-Port Channelized T3 Shared Port Adapters (SPAs) ideal for today's rapidly changing WAN environment. As an integral part of a service node where customer bandwidth needs are uncertain, the Cisco Channelized T3 SPA allows service providers to avoid determining beforehand how ports will be allocated between DS - 0, DS-1, and DS-3 connections. For enterprise remote-site connections, the flexibility to support DS-0, DS-1, and DS-3 connections means the Cisco 2- and 4-Port Channelized T3 SPA reduces equipment expenditures by integrating the capabilities and services of numerous port adapters onto a single SPA. It also provides investment protection by growing with the enterprise to meet the needs of today's DS-0 and DS-1 and tomorrow's T3 aggregation networks.
