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 TRAU Protocol Analyzer software.

Speaking to the press, Mr. Vijay Kulkarni CEO of the company said, “GL's TRAU Analyzer is used to non-intrusively monitor TRAU frames at the A-bis interface (BTS to BSC links), and A-ter interface (BSC to MSC links). Application can automatically detect and capture TRAU frames of half rate (HR-8 kbps) or full rate (FR-16 kbps). Various codecs such as FR, EFR, AMR, AMR-WB, HR and Data are used for compression/decompression of speech. TRAU frames are decoded as per the specifications GSM 08.60 V 8.2.0 Release and GSM 08.61 V 8.1.0 Release.”

He added, “Analysis of TRAU calls, including detail statistics, wave graph, oscilloscope, spectral display for various codecs can be done using TRAU Packet Data Analysis (PDA) feature. It also allows users to play voice files to speaker, write speech data to a file, filter calls, detect digits and view graphs such as Active Calls, and Traffic Monitoring to identify Full Rate and Half Rate traffic with traffic type and direction in a pictorial format.”

Mr. Kulkarni further added, “A-bis Signaling can be monitored using GSM Analyzer (optional). Traffic Analyzer Detail View allows the user to have a detail look at one (or two) TRAU sessions that are part of a single call. The view is divided into two parts, which assists in any comparisons to be made between the two sessions.”

Some of the Important Features

·Displays Summary, Detail, Hex-dump, Statistics, and Call Trace Views, the contents of this view can also be copied to clipboard.
·Decode TRAU frames with codec such as FR (Full Rate GSM 6.10), HR (Half Rate), EFR (Enhanced Full Rate), AMR(Adaptive Multi Rate), AMR-WB, O&M, Data.
·Supports transmission rate of 16 kbps (GSM 08.60) & 8kbps (GSM 08.61).
·Decodes & displays frame synchronization bits, data bits & control bits.
·Supports filtering and search based on various TRAU frame direction, type, time alignment, CRC, and more.
·Ability to configure .INI file for advanced decoding options such as capturing of raw bits, set Discontinuous Transmission (DTX_MODE) for the EFR frame, and set/reset Discontinuous Transmission (DTX) bit for the uplink EFR frame.
·Exports Summary View information to a comma delimited file for subsequent import into a database or spreadsheet.
·Capability to export detail decodes information to an ASCII file.
·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.

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) 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.
