GL Communications Inc conveyed today the availability of its product - MAPS™ SS7 - that performs scripted SS7 Emulation.

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today the availability of its product MAPS™ SS7- that performs scripted SS7 Emulation.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ” GL's Message Automation & Protocol Simulation (MAPS™)-SS7 is an advanced protocol simulator/tester for SS7 simulation over TDM (T1E1) that can simulate Service Switching Point (SSP). The ISUP signaling specification conforms to ITU-T and ANSI standards. The tester supports testing network elements, error tracking, regression testing, conformance testing, load testing/call generation and generation of high volumes of ISUP traffic. MAPS™-SS7 functionality covers the ITU and ANSI variant of SS7 implementing MTP2, MTP3, and ISUP protocols. It is able to run pre-defined test scenarios against ISUP test objects in a controlled & deterministic manner.”

He added, “MAPS™-SS7 Conformance Scripts, suitable for conformance tests and functional tests, where test objects can be accurately, reliably and comfortably validated for compliance with ITU-T standard Q.761-764 and Q.784. It is suitable for manufacturers, network operators and service providers to address all stages of the development cycle, regression testing through to type approval, acceptance testing.”

Mr. Kulkarni further added, “The application gives the users the unlimited ability to edit SIP messages and control scenarios (message sequences). "Message sequences" are generated through scripts. "Messages" are created using message templates.”

Some of the Important Features:
·SS7 (SSP) simulation over TDM (E1/T1)
·Supports transmission and detection of TDM traffic - digits, voice file, single /dual tones
·Multiple E1/T1 line interfaces supported
·User-friendly GUI for configuring the SS7 MTP Layers
·User Configurable Signaling Links
·User-configured Circuit Mapping, i.e defines Circuit Identification Codes (CIC) and map these CICs to Timeslots/Trunks in order to enable Voice/Data traffic
·Supports MTP2 and MTP3 protocol machine
·Multiple MTP links
·Access to all ISUP Message Parameters Initial Address, Subsequent Address, Release messages, and more
·User controlled access to optional ISUP parameters such as timers
·Subsequent Address Message (SAM) configurations available
·Fully Supported Continuity Testing (COT) that includes both COT messages
·Ready scripts for conformance testing

bout GL Communications Inc.,

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.

GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.

GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) is available.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GL’s compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

GL’s wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.

GL’s Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.

GL’s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
