Short Description
4-Port Channelized T3 (DS0) Shared Port Adapter Version 2


The Cisco Interface 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.

The Cisco Channelized T3 SPA Version 2 is available in 2- and 4-port options. The ports can be independently configured as clear channel T3, Channelized T3 -> T1, n x T1, full-rate T1, Channelized T1, fractional T1, or DS-0 connections. When configured as clear channel T3 ports, connections to DS-3 and subrate DS-3 services can be provisioned. When configured as Channelized T3 ports, up to 112 T1 links or up to 1023 n x DS-0 channels can be supported, making the Cisco Channelized T3 SPA Version 2 a highly flexible interface for WAN provisioning. With integrated data-service-unit (DSU) functions on a per-port basis, the Cisco Channelized T3 SPA Version 2 is compatible with the large number of standards-compliant DSUs on the market.

Multilink Point-to-Point Protocol (MLPPP) is supported (in hardware) to enable link aggregation exceeding T1 capacity. Up to 12 individual T1s can be combined within a multilink bundle that appears to be a single IP link. This feature enables service providers to provision greater-than-T1 bandwidth incrementally, without requiring migration of the circuit and customer premises equipment (CPE) infrastructure to T3 facilities.

The Cisco Channelized T3 SPA Version 2 is hot-swappable and supports service-transparent online insertion and removal (OIR), allowing removal of the SPA without affecting the interface processor and other SPAs.

Applications
The Cisco Channelized T3 SPA Version 2 meets a variety of service interconnect requirements, including concurrent support for leased line and Frame Relay. Enterprises and service providers can connect the SPA into these services for aggregation of large numbers of remote-site and Internet service provider (ISP) customers into a central site.

The Cisco Channelized T3 SPA Version 2 offers many advantages, including:
- 2- and 4-port options
- Support for clear channel T3, Channelized T3 to T1, n x T1, full-rate T1, Channelized T1, fractional T1, or DS-0 connections
- Up to 4 T3 ports, 112 T1 ports, or 1024 n x DS-0 channels
- Integrated DSUs
- Support for all major encapsulations, including MLPPP and multilink Frame Relay (MLFR)
- Support for link fragmentation and interleaving (LFI) over Frame Relay (FRF.12) and MLPPP
