Cisco 2- and 4-Port Channelized T3 (DS-0) Shared
Port Adapters Version 2
Port Adapters Version 2
The combination of channelized and clear channel T3 functions makes the Cisco
®
2-
and 4-Port Channelized T3 Shared Port Adapters (SPAs) Version 2 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 Version 2
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 Version 2 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.

The Cisco I
nterface Flexibility
(I-Flex) approach combines SPAs and SPA interface processors (SIPs), providing an
extensible design that enables service prioritization for data, voice, and video services. Enterprise and service
provider customers can take advantage of improved slot economics resulting from modular port adapters that are
interchangeable across Cisco routing platforms. The I-Flex design maximizes connectivity options and offers
superior service intelligence through programmable interface processors that deliver line-rate performance. Cisco I-
Flex enhances speed-to-service revenue and provides a rich set of quality-of-service (QoS) features for premium
service delivery while effectively reducing the overall cost of ownership. This data sheet contains the specifications
for the Cisco 2- and 4-Port Channelized T3 (DS-0) SPAs Version 2 (Figure 1).
