“GL's Message Automation & Protocol Simulation (MAPS™) is a protocol simulation and conformance test tool that supports a variety of protocols such as SIP, SIP I, MEGACO, MGCP, SS7, ISDN, GSM, MAP, CAS, LTE, UMTS, SS7 SIGTRAN, ISDN SIGTRAN, Diameter and others. Along with automation capability, the application gives users the unlimited ability to edit messages and control scenarios (message sequences),” said Vijay Kulkarni, CEO of GL Communications.

He further added,MAPS™ High Density (HD) is an advanced bulk call generator used to simulate high volume calls. The HD version is a special purpose 1U hardware platform capable of high call intensity (hundreds of calls/sec) and high volume of sustained calls (tens of thousands of simultaneous calls/1U platform). Multiple 1U platforms can generate and sustain 100,000 to 200,000 calls all controlled from a single Master Controller. This network appliance provides a modular and flexible solution to generate real voice calls using industry standard voice codecs. For comprehensive information, user can refer to the Signaling and Traffic Simulator and High-Density Traffic Generator web pages.”

GL’s advanced bulk call generator can simulate a high volume of Voice over IP calls using the MAPS™ Server with PacketLoad and RTP HD Server appliances.
