The Cisco ASR 1000 series DSP-SPA is a single-width, half-height, high-power shared port adapter (SPA) digital signal processor (DSP) module that can be used in multiple Cisco platforms. The SPA-DSP provides voice service such as voice transcoding and transrating and dual-tone multifrequency (DTMF) interworking capability for the platforms that support SPA module.

The DSP-SPA helps position a peering session border controller (SBC) with another carrier's voice-over-IP (VoIP) network and helps provide access to the SBC in the service provider edge, enabling Session Initiation Protocol (SIP) trunking and aggregation of enterprise and residential customers.
