Architecture
This section briefly describes the Cisco BTS 10200 Softswitch architecture from an external components
perspective. It describes the following types of components:
• Call Agent, page 10-2
• Terminations, page 10-2
• Interfaces, page 10-3
The Cisco BTS 10200 Softswitch connects to a variety of media gateways (MGWs) using the Media
Gateway Control Protocol (MGCP), and supports MGCP 0.1. The Call Agent (CA) provides signaling
and call processing for the Cisco BTS 10200 Softswitch.
Media gateways provide bearer paths between voice and packet networks, as well as connection control,
endpoint control, auditing and status functions. These gateways are equipped with voice coders that
convert voice into packets, and voice decoders that convert packets into voice. Connections are grouped
in calls, which means that a call can have one or more connections. One or more Call Agents set up
connections and calls.
The SuperPoP/Regional Office hosts all the servers needed to provide solution services. The media
gateways are also typically located here where the PSTN trunks terminate.
