GL Enhances TDM, Packet & Wireless Protocol Analyzers

GL Communications Inc. announced today the release of its enhanced ISDN, GSM,MLPPP and SS1 Protocol Analyzers. Speaking to news persons, Mr. Vijay Kulkarni, CEO of the company said, "GL carries the widest array of protocol analyzers for TDM, Wireless, and Packet networks. Based on a uniform architecture with identical features and functions, they can be used flexibly for a wide variety of tasks, including

The GSM Analyzer is used to view

The GSM Analyzer is used to view and analyze GSM protocols using GL's field proven Ultra E1 or Ultra T1 internal cards or Laptop E1 or T1 portable external products. The Analyzer enhanced to support: Group Call Control (GCC) protocol (Specification - 3GPP TS 44.068 V9.0.0) is implemented to support VGCS (Voice Group Call Service) feature for GSM-R (Global System for Mobile Communications - Railway). And Broadcast Call Control (BCC) protocol (Specification - 3GPP TS 44.069 V9.0.0) is implemented to support VBS (Voice Broadcast Service) feature for GSM-R (Global System for Mobile Communications - Railway).

The ML PPP Analyzer can be used to capture and decode a host of PPP protocols exchanged between pairs of nodes over T1 E1 links. It provides useful analysis of the PPP, ML PPP, and MC ML PPP protocols which includes distribution of protocols, protocol fields, frame lengths and frame status. The analyzer is now includes VoIP Packet Data Analysis to analyze VoIP calls transported by TDM lines. It has also been enhanced with new decodes to support Compressed RTP and Multiplexed PPP.

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 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.

The broadest range of simulation

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.
