Speaking to the media, Mr. Jagadish Vadalia, Senior Manager of Product Development at GL said, “The Enhanced Bit Error Rate Test Application measures the correctness of data received on T1/E1 lines (contiguous and non-contiguous timeslots, sub-channels) according to a repetitive fixed or pseudo random pattern for a given transmission. It also supports sub-channel selection (fractional BERT within a timeslot) for finer control of testing on individual bits”. He added, “The application generates/detects framed, unframed, fractional, and sub channel BER patterns with a variety of standard static and pseudorandom data patterns such as QRSS, All Zeros/ Ones, CSU and NIU Loop-Up/Loop, and user defined patterns”.
Mr. Vadalia further added, “The Bit Error Rate Testing can be performed simultaneously in real-time or off-line mode on multiple cards along with a consolidated result view in tabular / graphical formats. The Tx and Rx settings can be independently controlled or set as coupled”.
New Features and Enhancements
• Non-contiguous timeslot and sub-channel selection (Fractional BERT within a timeslot);
• Testing on multiple cards simultaneously with a consolidated result view;
• Independent settings for Transmit and Receive configurations (timeslot and sub-channel selection);
• User defined patterns of size up to 32 bits;
• Enhanced error insertion capability;
• Real-time and offline graph view of events;
• Sophisticated logging feature using XML format.
About GL Communications, Inc.
Founded in 1986, GL Communications, Inc. (gl.com) is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, 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, OC-3, STM-1, analog four-wire, and analog two-wire interface cards and solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (HDLC, ISDN, SS7, CAS, GSM, GPRS, CDMA), and with capacities up to thousands of channels.
GL’s VoIP products generate / analyze thousands of calls simultaneously with traffic types such as voice files, digits, tones, noise, and fax using G.711, G.729, AMR, EVRC, and GSM codecs. Additional features include visual analysis, real-time listening, recording, and voice quality assessment using ITU algorithms PAMS, PSQM, and PESQ.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and CDMA 2000 networks. Connections can be made to any wireless phone with automated call control, GPS, mapping software, and real-time signal measurements.
GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160.
GL’s Network Surveillance and Monitoring products include Probes for TDM, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
