The Cisco SPA-4XOC3POS Shared Port Adapter Module delivers four OC-3 POS interfaces (STM-1) in a single module. As a Shared Port Adapter, it consolidates four independent OC-3 POS ports into one module for Cisco deployments that support SPA modules, enabling multiple OC-3 STM-1 POS streams to be carried through a single adapter. This 4-port OC-3 POS solution provides expanded POS connectivity within Cisco networks by housing four channels in a single module for compatible chassis.
