Multi-Interface Media Gateway controller aids TDM-IP network test

Jagdish Vadalia, a Senior Manager for product development of the company said, “In a hybrid TDM-IP network, when a call is originating from PSTN, SS7 signalling in the PSTN is translated to SIGTRAN by the SG.  TDM traffic is repackaged into RTP packets by the MG to forward the call to IP network.  A Media Gateway Controller (MGC) controls the various elements within the IP Network using SIP, MEGACO, and MGCP protocols.  The reverse may happen if the call is destined to PSTN.”

He added, “MAPS MGC is a multi-interface simulator configured to handle signalling and call control between the SG and MG across the network. MAPS MGC simulates SS7 signalling procedure between the SGs on both the ends of the network while handling bulk traffic (RTP Media) between the MG terminals using MEGACO/MGCP signalling.”GL's Message Automation & Protocol Simulation (MAPS) supports MEGACO and MGCP protocols which can simulate MGC to test Media Gateways with various types of calls. 

With the purchase of MAPS SIGTRAN, MAPS MEGACO or MAPS MGCP and RTP Core License, users can simulate transmission and detection of various RTP traffic such as Digits, Voice File, Single Tone, Dual Tones, IVR, FAX and Video.

With regular RTP Traffic, the maximum simultaneous calls up to 2500, and calls per second (cps) up to 250 is achievable.  Almost all industry standard voice/video codecs are supported.

GL’s MAPS MEGACO and MAPSMGCP are also available in High Density version (HD) and are capable of high call intensity (hundreds of calls/sec) and high volume of sustained calls (tens of thousands of simultaneous calls/platform).
