TRAU Toolbox™ software

GL's TRAU Toolbox™ is an ideal tool to test network elements at A-bis and A-ter interface. The tool can be used to create, monitor, and terminate multiple TRAU/GSM traffic (TRAU sessions).

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 Toolbox™ software.

Speaking to the press, Mr. Vijay Kulkarni CEO of the company said, “GL's TRAU Toolbox™ is an ideal tool to test network elements at A-bis and A-ter interface. The tool can be used to create, monitor, and terminate multiple TRAU/GSM traffic (TRAU sessions). Once the TRAU session is created, different kinds of audio/voice/digits can be generated and analyzed on GSM call with various codecs.”

He added, “TRAU Toolbox™ can emulate TRAU node at BSC/MSC end or CCU node at BTS end including the compression/decompression of speech that takes place at TRAU side or Mobile side. TRAU frames are time-aligned according to control information. The traffic generated by a BTS is transported to the corresponding BSC across a network is referred to as the backhaul network. The TRAU Toolbox™ can be used to test this backhaul network as well.”

Main Features

·Used to test the backhaul network.
·Users can create TRAU GSM traffic sessions by specifying the device number, channel & subchannel.
·Can create multiple sessions of Uplink or downlink in 8/16 Kbps
·Work on 3 modes: Transmission (Tx) side or only Receiving (Rx) side or both Rx & Tx.
·Supports speech codec for verification of correct voice transmission which includes GSM codecs such as GSM 6.10(FR), Half Rate (HR), Enhanced full rate (EFR), Adaptive multi Rate (AMR - Rates 4.75, 5.15, 5.90, 6.70, 7.4, 7.95, 10.2, & 12.2 kbps), Adaptive Multi Rate-Wide Band (AMR-WB –Rates 6.60, 8.85, 12.65 kbps) and Data, Data 14.5kbps Sync, and Data 14.5kbps(Extended Data).
·Phase Alignment can be applied to AMR or AMR-WB modes to change the mode to the requested modes.
·Logical AND, OR or XOR impairments can be applied to a TRAU frames.
·Idle speech frames can be generated in case of GSM and EFR downlink codec if there is no speech frames to transmit.
·Capability to apply DTX to EFR and AMR codec
·Supports Loopback and Pass Through modes
·Time Alignment Delay or advance can be inserted in the TRAU frames.
·Graphical display features include the ability to monitor TRAU stream contents using an oscilloscope and spectrum analyzer.
·Other features allow the user to generate and analyze test tones, in-band signaling tones such as DTMF, MF, MFR2, playback and record voice files.

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.
