The Cisco VXSM is a high-density voice service module with time-division multiplexing (TDM) interfaces ranging from T1/E1 to channelized OC-3/STM-1 (refer to Figure 1). It provides service providers with carrier-class capabilities for high capacity and reliability for voice-over-IP (VoIP) services. The Cisco VXSM scales to 8064 DS0s per module and is fully redundant to maintain active calls upon switchover.

The Cisco VXSM architecture combines a high-performance voice services engine with onboard digital signal processors to provide advanced voice processing and features that allow quick development and deployment of VoIP services. The Cisco VXSM offers carrier-grade voice quality with a full suite of voice, modem, and fax features. The Cisco VXSM, together with a softswitch, provides maximum deployment flexibility for various packet voice networks based on the Media Gateway Control Protocol (MGCP), PacketCable™ Trunking Gateway Control Protocol (TGCP), H.248, H.323, and Session Initiation Protocol (SIP).
