Tunnelling Gateway (TG) Configuration

SS7 Link Replacement

In fixed line networks, Service Providers have long been forced to accept both recurring costs and the delays associated with activating long-haul SS7 digital circuits. SS7 links for SCP to MSCs, SSPs, SEPs etc. can cost local carriers approximately $1000 per month to rent from ex-national carriers – sometimes more. Configured as a Tunneling Gateway (TG), the AdaxGWs minimize disruption to the existing SS7 infrastructure, by simply replacing expensive leased lines between SS7 nodes with IP. By tunneling the SS7 traffic through the IP network without converting the SS7 to SIGTRAN, the TG avoids the complexity of typical Next Generation solutions while still delivering the benefits of future telecom technology today.

SS7 Tunneling Over IP Protocol Stack

The TG configuration offers a quick and economic solution for connecting legacy SS7 network elements together across IP networks, producing very significant savings in network transmission costs for SS7 signaling systems while preserving SS7 at the end points. The TG offers an appealing migration strategy for operators, allowing them to take advantage of packet transport while phasing in native IP signaling connectivity and preserving the same level of services, quality and reliability as a traditional PSTN.
