Press Release: GL Announces Enhanced Call Capture and Analysis Software for T1 E1
Gaithersburg, Maryland, USA - June 22, 2009 - GL Communications Inc., announced today the release of Enhanced
Call Capture and Analysis for T1 E1 software and hardware that allows triggered recording of calls, either automatically or manually
directly from T1, E1, or Analog lines. Briefing the news to the press Mr. Vijay Kulkarni, President of GL said, "The Enhanced Call Capture and Analysis (CCA)
application can initiate triggered recording of calls, either automatically or manually directly from T1 E1 Analog lines. The application uses any of three platforms:
HD PCI Ultra T1 E1 Cards, or GL's USB Portable T1 E1 Analyzer Units, or Universal T1 E1 Analyzer Cards. Any of these platforms can interface non-intrusively
with T1 E1 Analog lines. Automatic call capturing can be triggered from either direction of transmission, east or west".
Mr. Kulkarni further added, "The application provides auto capturing support. After capture, captured calls can be played back and analyzed in time and
spectral modes using a commercial sound card, built-in high fidelity speakers, and audio viewing software such as Adobe Audition or Goldwave. CCA software
works in conjunction with the CMU (Call Management Utility), to automatically identify captured calls and calls being captured. Users can listen to calls that
are in progress. The CMU is especially helpful when a large number of calls are captured such as over a weekend or on many trunks".
Some of the Important features:
- Automatic or manual initiation of call recording
- Real-time display of signaling bits for all channels in both directions
- 'Scan' or 'Channel' mode for call initiation detection and capture
- User specified record time
- Automatic termination of recording, or Manual termination
- PCM data captured to two synchronized disk files (east and west directions) for post processing
- Call recording for post analysis
- Analysis of single/dual tones, DTMF and MF digit analysis (frequency, power, duration)
- Analysis of call quality (speech levels, noise levels, echo return loss, speech clipping, impulse noise, and other impairments)
- Call activity, call density, and call volume analysis

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,
GL's TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, 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, etc.), 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, video, tones, noise, and fax
using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. Additional features include visual analysis, real-time listening, and recording. The
product line also includes a Software Ethernet Testing capability that checks frame transport and throughput parameters of Ethernet and IP networks.
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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless,
and Landline) are all available.
GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS 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 compliance testing per G.168 and G.160
across TDM, IP, VoIP and Wireless networks. GL's wirelss 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 intelligence. Centralized or distributed access, efficient transport and database
loading allow compatibility with 3rd party and standards based monitoring systems.
