Cisco 8-Port Channelized T1/E1 SPA provides one of the greatest densities currently offered in the industry at 8 ports per SPA and up to 32 ports per SIP. At a cost per T1/E1 port less than that of a standard serial port with external channel service unit/data service unit (CSU/DSU), the Cisco 8-Port Channelized T1/E1 SPA is cost-effective for all WAN connectivity.
The SPA is designed to provide a full 8-port channelized solution for the Cisco 6500,7600 and the 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 SPA eliminates the need for separate interface types for separate connection requirements.
Multilink Point-to-Point Protocol (MLPPP) is supported (in hardware) to enable link aggregation greater than T1 capacity. Up to eight individual T1s can be combined within a multilink bundle that appears to be a single IP link. This 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 8-Port Channelized T1/E1 SPA is hot-swappable and supports service-transparent online insertion and removal (OIR), allowing removal of the SPA without impacting the interface processor and other SPAs.

The Cisco 8-Port Channelized T1/E1 SPA is ideal for service providers and large enterprises looking to cost-effectively deploy high-density terminations of multiple remote sites (Figure 2). The SPA helps enable applications that require remote and branch-office locations to be terminated on a single router in a corporate enterprise network. For service provider applications where only DSU functions are required (for example, at sites colocated with a carrier), the Cisco 8-Port Channelized T1/E1 SPA provides high port density at a reduced cost per port. For E1 applications, the channelized E1/G.703 interface allows direct connectivity to 120-ohm G.703 lines.
