“ss7SS7 C7 Signalling Gateway

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.

SS7 Signalling Gateway

SS7 to IP, SIGTRAN Gateway

svi mg1000 smv2Scaling from 2 x SS7 signalling links to 256 x SS7 signalling links on a single chassis and 512 x signalling links on a full dual redundant/ high availability system provides a fully scalable product solution.

The SVI-SG provides an SS7 signalling gateway environment backhauling TDM SS7 information using international IETF standards of SIGTRAN.

SS7 SIGTRAN adaption layersThe SIGTRAN protocol range allows for the backhaul of SS7 signalling over IP using the IETF standards, this allows the SVI-SG SS7 SIGTRAN Gateway to be compliant and ready to interconnect into any other SIGTRAN compliant environment.

The SS7 signalling gateway provides a full range of SIGTRAN user adaption layers (M2UA, M2PA, M3UA and SUA) allowing for different layers of the SS7 protocol to be presented into the IP environment depending on the infrastructure requirement.


The SVI-SG SS7 Signalling Gateway is supplied as standard with a rich set of operating features:-

SS7 Signalling Gateway (SIGTRAN) Deployment Scenarios

SIGTRAN Deployment

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.
