The enhanced TRAU Suite of products provides users a greater ease and utility in analysis and simulation of wireless networks
Gaithersburg, Maryland, USA (Vocus) February 25, 2010
GL Communications Inc. announced today the release of enhanced Wireless Analysis and Emulation software– These tools are used for emulation and analysis of traffic at the A-bis interface (BTS to BSC links), and A-ter interface (BSC to MSC links) in the wireless network infrastructure. Speaking to the press, Mr. Karthik Ramalingam, development manager, said, “TRAU (Transcoder/Rate Adapter Unit) frames between the A-bis interface (BTS to BSC links), and A-ter interface (BSC to MSC links) perform the function of compression/decompression of speech channels within the radio cellular network. TRAU frames carry speech, data, and O&M information at full rate or half (8/16 kbps) rate and control information, over T1/E1 in a GSM network”. He added, “To reduce bandwidth requirements on the BTS-BSC and BSC-MSC interface, service providers use transcoders or voice compression technology - known as TRAU, or Transcoder/Rate Adapter Unit. TRAU frames between the BTS and BSC/MSC carry compressed speech, data, and O&M frames over T1 E1 lines”.
Mr. Ramalingam, further added, “The enhanced TRAU Suite of products provides users a greater ease and utility in analysis and simulation of wireless networks”.
GL's T1/E1 Analyzers (CARD or USB Based) can be equipped with software for:
•Real-time TRAU Protocol Analyzer
•Offline TRAU Protocol Analyzer
•TRAU Traffic Playback
•Scripted (Automated) TRAU Engine
•Scripted (Automated) TRAU Tx/Rx Test
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, STM-1, 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, etc.), and with capacities up to thousands of channels.
GL’s VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. 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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS 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 compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
