Multi-channel Bit Error Rate Testing (MCBERT) measures correctness of data received on T1 E1 lines/timeslots with stored data in a reference file.
Gaithersburg, Maryland (PRWEB) November 15, 2011
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 Multi-Channel Bit Error Rate Test software product.
Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ”Multi-channel Bit Error Rate Testing (MCBERT) measures correctness of data received on T1 E1 lines/timeslots with stored data in a reference file. The application can work in real-time with data currently being received on T1 E1 lines/timeslots, or off-line with data stored in a file. The on-line T1 E1 testing can be done on full or fractional T1 E1 timeslots.”
He explained, “During real-time analysis, the user chooses Reference file. (Program loads this to a 'circular' buffer.) Proper device number and timeslots are selected to specify the online data to be verified. Mode of received data (64kbps, n x 64kbps or n x 8kbps) is selected depending upon timeslot specification. Application is started and the MCBERT statistics are observed.
During Offline Analysis data is captured into hard disc using applications like Record data to a file. And captured file is selected using the 'Data from File' option and the reference file is selected using 'Pattern File' option.”
Mr. Kulkarni further added, “The following independent streams can be compared in real time to a chosen pattern file:
·Multiple 64kbps (56kbps) independent stream channels (need NOT be contiguous)
·A hyperchannel per T1 E1 (n x 64kbps timeslots, where n = 1..24 T1, 1.32 E1; contiguous timeslots) line/trunk
·Multiple subchannels n x 8 kbps (8k, 16k…56k). For example, for T1 it could be up to 24 x 8 separate 8kbps subchannels (eight subchannels per timeslot).”
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) are all 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.
