Cisco SPA-8XT3/E3=

The Cisco Clear Channel T3 / E3 SPA offers high-density, highly manageable T3 / E3 line connectivity and termination. With integrated line-interface data service units (DSUs) that allow T3 / E3 lines to be directly terminated on a Cisco router, the Cisco Clear Channel T3 / E3 SPA simplifies T3 / E3 line management, replaces provisioning costs, and makes valuable rack space available. To support the wide range of operational environments and to offer great flexibility in provisioning Clear Channel T3 / E3 connections, the Cisco Clear Channel T3 / E3 SPA takes a big step and brings together proprietary subrate and scrambling features of T3 / E3 Data Service Unit (DSU) vendors. Subrate support in the Cisco Clear Channel T3 / E3 SPA maximizes the application of this product in service provider environments for tiered T3 services. By simultaneously supporting interoperability with a wide range of third-party DSU vendors, the Cisco Clear Channel T3 / E3 SPA offers the flexibility to support installed equipment without committing customers to a proprietary solution. The Cisco Clear Channel T3 / E3 SPA 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.
