POI to MSC Backhaul Application
Today, many mobile operators are improving their competitiveness by actively expanding their service provision capabilities to new markets. The main goal of such a strategy is to provide the fastest network and service rollout at the lowest cost.
In implementing this strategy, mobile operators are challenged to expand the connectivity of their existing MSC switches to PSTN and/or MSC switches of other operators located in other regions; for this purpose, Point Of Interconnection (POI) sites are built. Usually this interconnection demands costly long-distance transmission facilities to backhaul the traffic between the POI's and the operator's MSC.
In these applications, an I-Gate-based DCME-over-IP system can ensure a faster turnover period and lower OpEx than any alternative solution. A POI to MSC backhaul network includes one or more I-Gate media gateways at the operator's MSC site (hub site) and I-Gate media gateways at the POI's. The uncompressed traffic (64 kbps, G.711 encoded calls) from the remote PSTN and MSC switches is compressed by the POI's I-Gate media gateway and carried over the long-distance transmission network to the I-Gate media gateway(s) at the hub site, where the received payloads are decompressed to the original 64 kbps, G.711 format and transmitted to the MSC.
