Gaithersburg, Maryland (PRWEB) December 05, 2012
GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, announced today the availability of its versatile Multi-Channel TRAU Record/ Playback Emulation and Analysis software.
Speaking to media persons, Mr. Jagdish Vadalia Senior Manager for Product Development of the company said, ” GL provides client –server based TRAU Record/Playback, and TRAU Emulation & Analysis modules. The WCS TRAU Tx/Rx Test (TrauTerr) module is a GUI based client as well as command-line based client application, which can simulate & analyze TRAU/CCU (BTS or BSC end) on GL’s T1/E1 cards.
The application is capable of generating and receiving TRAU traffic (with or without impairments) based on the codec type, and time alignment (if specified). The frames are transmitted through the 16 or 8 kbps channels.”
He added, “Traffic source can be sequence number, HDL files (containing trau frames), flat binary file, and user-defined frames (ASCII HEX string/ file). This application can be used to test the correctness of the received data, by comparing with predefined patterns.”
He added, “The File based TRAU Record /Playback is a command-line based client module that allows transmission / reception of TRAU frames in *.hdl file format. GL's Windows Client/Server software allows the user of T1/E1 analysis cards, the capability of remote operation, automation, and multi-site connectivity. Server software can run multiple tasks simultaneously at the request of the Client software.”
Some of the Important Features:
·Simulates TRAU traffic over Abis and Ater interfaces.
·Can be used to test the backhaul network. (Backhaul network is the traffic generated by BTS which is transported to the corresponding BSC across a network).
·Ideal solution for remote access and automated testing using command line scripts.
·Can create multiple sessions of uplink or downlink in 8/16 Kbps.
·Supports all speech codec for verification of correct data 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) and Adaptive Multi Rate-Wide Band (AMR-WB –Rates 6.60, 8.85, 12.65 kbps).
·Payload traffic generation and verification using Sequence number, HDL file (containing TRAU frames), Flat binary file, and User-defined frame (ASCII HEX string/file) for each session independently.
·Time Alignment can be applied in the TRAU frames.
·Supports various impairments - CRC error, frame duplication, and more.
·Provides detailed test (Tx/Rx) results for each TRAU session.
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.
