GL Conveys The Availability of its UMTS Protocol Analyzer Software

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 UMTS Protocol Analyzer software.

Speaking to the press, Mr. Vijay Kulkarni CEO of the company said, "UMTS being an access network in the mobile communication area provides a common interface to both GSM and GPRS core network. UMTS is capable of handling both Circuit-Switched as so then as Packet-Switched data simultaneously through its UTRAN network."

He added, "GL's UMTS analyzer is capable of capturing, decoding and performing various test measurements across various interfaces i.e. Iub, Iur, IuCS and IuPS interfaces of the UMTS network. To boot, it supports ATM as the transport layer. It helps in fault diagnosis and troubleshooting of UMTS network. Multiple instances of UMTS Analyzer can run simultaneously capturing data on several T1/E1 lines."

·Performs numerous measurements across Iub, Iur, IuCS and IuPS interfaces ·Displays Summary, Detail, Hex-dump, Statistics, and Call Trace Views, the contents of this view can as well be copied to clipboard ·Call Trace capability over IuCS and IuPS interfaces ·Search and filtering capabilities for both real-time as then as offline analysis ·Decodes different control plane protocols i.e. NBAP, RNSAP, RANAP, ALCAP, SSCOP etc and user plane protocols i.e. Iu-UP, Iu-FP, AMR etc ·Decode NAS protocols along with the UTRAN specific protocols ·User can configure VPI/VCI values for PVCs carrying NBAP, RNSAP, RANAP and ALCAP messages to enable decoding of the said protocols ·Ability to configure .ini file for VPI & VCI ·CRC verification for AAL5 carrying packet data ·Capability to export summary view details to comma separated values format for subsequent import into a database or spreadsheet ·Capability to export detail decode information to an ASCII ·Any protocol field can be added to the summary view, filtering, and search features providing users more flexibility to monitor required protocol fields ·Remote monitoring capability using GL's Network Surveillance System

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP (Voice over Internet Protocol) 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 and traffic simultaneously with traffic types just as frames, packets, voice files, digits, video, tones, noise, and fax. Nearly 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 as well 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 product line complements all of GL's products. Using ITU-standard algorithms, GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks is available.

GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE (Long Term Evolution, latest standard in the mobile network technology) 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 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 just 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.

Wide variety of communications facilities

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 nearly 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.
