PSTN Gateway
IMS defines a number of functional elements that are involved in establishing a gateway to the PSTN. These include: a Breakout Gateway Control Function (BGCF) to determine the network for the PSTN breakout, a Media Gateway Control Function (MGCF) that controls trunking gateways and signaling interworking, and the Trunking Media Gateway and Signaling Gateway Functions (T-MGF / SGF) for the transit of voice calls and signaling between IMS and the PSTN.
GENBAND provides IMS compliant gateway and control platforms that meet the extensive needs of service providers migrating their networks to IMS. The S-Series security platforms use the Multi-protocol Session Exchange (MSX)™ feature set to provide the advanced routing logic required in the BGCF as well as additional IMS security and session management functions, and the C3 Signaling Controller interworks SIP with H.248 to provide high throughput MGCF capabilities.
For PSTN interconnection, GENBAND provides the latest in media processing with the highly scalable G9 Converged Gateway that supports tens of thousands of ports and features a high capacity, integrated signaling gateway. The G9 additionally supports a Media Resource Function (MRFP) to perform transcoding and other media adaptation services in IMS networks.
