Adapter Version 2
Today's successful businesses require more bandwidth and feature-rich services to
maintain a competitive advantage. To serve these business customers better, service
providers need scalable solutions that not only increase service agility and flexibility,
but also reduce overall network complexity, the time required to provision new
services, and the total cost of ownership. The Cisco

1-Port Channelized STM-1/OC-3
Shared Port Adapters (SPAs) Version 2 addresses these needs by sharply reducing
the amount of aggregation equipment and interconnectivity needed between edge and
backbone routers. The Cisco 1-Port Channelized STM-1/OC-3 SPA provides Cisco
7600 and Cisco ASR 1000 and ASR 9000 Series Aggregation Services Routers with
support for T1/E1 aggregation. Designed for telcos and Internet service providers
(ISPs), the SPA includes one OC-3/STM-1 port, which can be configured with multiple
channels of n x T1, T1, fractional T1, or DS-0 in a SONET environment or n x E1, E1,
fractional E1, or 64 kbps in an SDH environment.

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. 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 1-Port Channelized STM-1/OC-3 SPA Version 2 as shown in Figure 1.
