Port Adapters Version 2
Demand for high-capacity corporate backbones, for high-speed access to the global
Internet, and for trunking connections for service provider internetworking have led to
growth in clear channel T3/E3 connections that has outpaced all other types and
speeds of leased lines. This growth places tremendous strain on service providers
and network managers who must provision and manage new T3/E3 connections. The

Clear Channel T3/E3 Shared Port Adapters (SPAs) Version 2 for the Cisco
7600 and Cisco ASR 1000 and ASR 9000 Series Aggregation Services Routers offer
high-density, highly manageable T3/E3 line connectivity and termination. With
integrated line-interface data service units (DSUs) that allow T3/E3 lines to be directly
terminated on a Cisco router, the Cisco Clear Channel T3/E3 SPAs Version 2 simplify
T3/E3 line management, reduce provisioning costs, and make valuable rack space
available.

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 Cisco I-Flex design maximizes connectivity options and offers
superior service intelligence through programmable interface processors that deliver line-rate performance. 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 Clear Channel T3/E3 SPAs Version 2 (Figure 1).
