SVI-SG SS7 SIGNALLING GATEWAY FEATURES

With low cost, reliable, high bandwidth IP networks available for distribution of signalling, the SS7 Signalling Gateway provides the means to bridge the SS7 network from the traditional PSTN and Mobile TDM interconnects to IP.




Deployment Scenarios

Typical SS7 to IP Deployment

The SVI-SG SS7 signalling gateway can be deployed to replace expensive dedicated longhaul SS7 links by backhauling the SS7 signalling over IP.

Distributed Network

Deployed in a distributed network architecture delivering the SS7 signalling to a centralised softswitch / media gateway controller.
