8-Port Channelized T1/E1 Shared Port Adapter (SPA) Version 2 takes
advantage of the Cisco I-Flex approach, which combines shared port adapters and
SPA interface processors (SIPs). This extensible design helps prioritize data, voice,
and video services. Enterprise and service provider customers can take advantage of
improved slot economies, which result from modular port adapters that are
interchangeable across Cisco routing platforms. The I-Flex design increases
connectivity options and offers superior service intelligence through programmable
interface processors that can 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.

Product Overview
Today’s global enterprise and service provider networks require diverse networking solutions to meet both
economic and evolving connectivity needs. The demand for high-density, cost-effective solutions increases as
corporate intranets expand to include more regional offices and increased numbers of remote and mobile users.
The Cisco 8-Port Channelized SPA T1/E1 Version 2 (Figure 1) provides one of the greatest densities currently
available in the industry at 8 ports per SPA and up to 32 ports per SIP. The cost per T1 or E1 port is less than that
of a standard serial port with external channel service unit (CSU) or data service unit (DSU), which makes the
Cisco 8-Port Channelized T1/E1 SPA Version 2 cost-effective for all WAN connectivity.
This SPA is designed to provide a full 8-port channelized solution for Cisco 6500 Series, 7600 Series, ASR1000
Series, ASR9000 Series and 12000 Series Routers. The interfaces can be channelized, fractional, or unframed
(E1) with up to 256 independent High-Level Data Link Control (HDLC) channels definable for T1 and E1
applications. With these capabilities, the Cisco 8-Port Channelized SPA T1/E1 Version 2 eliminates the need for
separate interface types for separate connection requirements.
