To permit our customers to emulate, test, and verify GPRS Gb functionality, GL has enhanced its MAPS™ (Message Automation & Protocol Simulation), a multi-protocol, multi-technology platform to emulate GPRS Gb Interface over IP.
Gaithersburg, Maryland (PRWEB) March 19, 2013
GL Communications Inc. announced today the release of its latest product MAPS™ GPRS Gb Interface Emulator software.
Speaking to reporters, Mr. Karthik Ramalingam, Senior Manager for product development of the company said, “GPRS, or General Packet Radio Service, was introduced (in the late 90's and early 2000's) to enhance data carrying capabilities of the basic GSM Network. Initially it used the conventional T1 E1 transport and frame relay protocol. As data traffic (IP) has steadily increased, the use of IP interface provides many advantages including increased throughput, capacity, and economy. Also as the wireless infrastructure evolves toward IP, the migration of 2G IP based systems to 3G and 4G is also more efficient and economical.”
He added, “To permit our customers to emulate, test, and verify GPRS Gb functionality, GL has enhanced its MAPS™ (Message Automation & Protocol Simulation), a multi-protocol, multi-technology platform to emulate GPRS Gb Interface over IP. MAPS™ also supports many other protocol families including TDM, IP, ATM, and Wireless.”
Mr. Ramalingam further added, “Besides testing network elements (SGSN and BSS), the tester also involves error tracking, regression testing, and load testing/call generation. MAPS™ GPRS Gb interface Emulator supports various procedures including Network Service Control, Identity Check, Combined GPRS / IMSI Attach, and Routing Area Update. It can run pre-defined test scenarios against the interface test objects in a controlled & deterministic manner.
“The emulator also supports powerful utilities like Message Editor, Script Editor, and Profile Editor which allow new scenarios to be created or existing scenarios to be modified as per the supported protocol standards.”

About 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) are all 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.
