The combination of channelized and clear channel T3 functions makes the Cisco 2-Port Channelized T3 SPA 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 DS0, DS1, and DS3 connections. For enterprise remote-site connection, the flexibility to support DS0, DS1, and DS3 connections means this 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 for both today's DS0 and DS1 aggregation networks and tomorrow's T3 aggregation networks.
