GL Announces High-Density Call Generator for IP & Wireless Networks

Gaithersburg, Maryland, USA - November 07, 2014 - GL Communications Inc., announced today its latest product High-Density Call Generator for IP and Wireless Networks - referred to as MAPS™ HD (Message Automation and Protocol Simulation High Density).

Speaking to reporters, Mr. Jagdish Vadalia, a Senior Manager for Product Development of the company said, “MAPS™ is GL’s standard framework for emulation of IP, TDM, and Wireless protocols. 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.

Testing IP network performance with high sustained call volume and high call intensity is increasingly important to Wireless Carriers, Internet Service Providers, and Equipment vendors - to ensure that quality of experience does not degrade with call intensity, volume, or protocol. Load and stress testing are important to verify stability of the IP network and network elements during pre and post deployment. This requires an advanced network appliance which can generate high volume calls with traffic. In addition, packets must be delivered with high precision timing, zero packet loss and in the proper order.”

He added, “GL’s MAPS™ HD is a high density multi-protocol, multi-technology network appliance that performs signaling and traffic generation for a vast array of communication protocols covering IP and Wireless networks. It supports simulation of SIP UA, IMS SIP UE, SIP I+T, SIGTRAN, IuCS, MGCP, NCS, H.248/Megaco, Cisco SCCP (Skinny), Clear Channel (No Call Control) and provides non-reference-based voice quality using E-model (R-factor) and MOS with five mapping scales.

The network appliance provides a modular and flexible solution to generate real voice calls using industry standard voice codecs such as G.711 A/µ-law, G.722, G.722.2 (AMR-WB), G.722.1, G.726, G.729A/B, GSM (EFR, FR and HR), AMR (Narrowband and Wideband), EVRC, EVRCB, EVRC-C, iLBC, Speex, SpeexWB, RFC 2833, and user-defined codecs for voice and tones.”

Mr. Vadalia further added, “Through MAPS™ inherent scripting architecture, end-to-end testing of complex networks like Next Generation Voice Networks, Unified Communications, and IMS & Contact Centers is possible.

The network appliance can simulate a complete protocol state machine and offers ‘syntax-ready commands’ to easily build scripts. It provides ready-to-run scripts for simulating important call scenarios or procedures. Its syntax-ready commands in script reduce the dependency on technically skilled resources and its re-usability of scripts, messages and profiles reduces ‘time-to-market’. Customized test scenarios can be defined to build valid or invalid test cases.

User can modify any signaling messages, message parameters, and/or information elements. User can also add, modify or remove any optional parameter depending on specific feature of interest. Packet level fault insertion can be performed by impairing any bit / byte of a message. “
