Product Line(s)

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 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.
