The SVI_MGC allows carriers to deploy a fully
distributed network architecture – with signalling/
media gateways deployed at remote POPs
backhauling SS7 signalling over SIGTRAN M2UA/
M2PA/ M3UA into a centralised MGC.
This provides centralised routing capabilities,
centralised billing and can allow carriers to present a
single SS7 point code to all their SS7 POPs.
