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 SPA addresses these needs by sharply reducing the amount of aggregation equipment and interconnectivity needed between edge and backbone routers. The SPA provides Cisco 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 nxT1, T1, fractional T1, or DS-0 in a SONET environment or nxE1, E1, fractional E1, or 64 kbps in an SDH environment.

When the SPA is configured in SDH framing mode, it is capable of supporting channelization into 63 independent E1 channels (VC-12 mapping). When configured for SONET framing mode, the SPA is capable of supporting channelization into 84 independent T1 channels (VT1.5 mapping or CT-3 mapping into STS-1).

Multilink Point-to-Point Protocol (MLPPP) is supported in hardware to enable link aggregation greater than T1. Up to 12 individual T1s can be combined within a multilink bundle that appears to be a single IP link. This allows service providers to provision greater-than-T1 bandwidth on an incremental basis, without requiring migration of the circuit and customer premises equipment (CPE) infrastructure to T3 facilities. A maximum of 42 multilink bundles can be configured on each SPA with at least two T1 links in each bundle.

The Cisco 1-Port Channelized STM-1/OC-3 SPA is hot-swappable and supports service-transparent online insertion and removal (OIR), allowing the SPA to be removed without impacting the carrier card and other SPAs.
