Cisco Media Gateway Controller Software

The Cisco MGC software is part of several solutions that perform call processing, protocol conversion, and call switching and routing functions. The combination of software and the Sun Microsystems host server that works with all supported solutions is called the Cisco MGC host.

The Cisco MGC host interconnects Cisco media gateways to a circuit-switched time-division multiplexing (TDM) network, which offloads the signaling to an out-of-band network so that available bandwidth increases. Cisco Signaling Link Terminals (SLTs) are used to terminate Signaling System 7 (SS7) and pass signaling information to the Cisco MGC host.

In release 9 of the Cisco MGC software, the Cisco PGW 2200 (previously the Cisco VSC3000 or Cisco SC2200) provides a unified interconnection for dialup services, MGCP, SIP, and H.323, allowing service providers to deploy and operate multiple network solutions while maintaining a stable interconnection to the PSTN
