Press Release: GL Announces Multi-Interface Media Gateway Controller

Gaithersburg, Maryland, USA – September 12, 2016 - GL Communications Inc., announced today its latest Multi-Interface Media Gateway Controller that can be configured to simulate end-to-end call between the Signaling Gateway (SG) and Media Gateway (MG) by simulating SIGTRAN, MEGACO and MGCP interfaces in order to test a hybrid TDM-IP network.

Speaking to the press, Mr. 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 signaling 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 addedMAPS™ MGC is a multi-interface simulator configured to handle signaling and call control between the SG and MG across the network. MAPS™ MGC simulates SS7 signaling procedure between the SGs on both the ends of the network while handling bulk traffic (RTP Media) between the MG terminals using MEGACO/MGCP signaling.

Mr. Vadalia further explained, “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, one 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.

He further added, “GL’s MAPS™ MEGACO and MAPS™MGCP 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).
