T1 E1 Voice Call Management Utility

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 T1 E1 Voice Call Management utility software that provides complete call records for each captured file.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, " Managing recorded voice calls is essential especially when recording for extended periods of time. It is as well easy to manipulate the recorded voice calls by filtering the calls choosing either called or calling number, length of call etc. GL's Call Management Utility, is an application coupled with the GL's T1 E1 Call Capture and Analysis, that provides all the necessary management tools to perform function of recording voice calls. Call records are on the spur of the moment generated, indexed, and displayed once a voice recording over T1 or E1 lines is completed by the CCA."

He added, "Recorded calls can be furthermore filtered or played back or analyzed as required. All relevant information associated with each recorded call is included just as, timestamp, timeslot, length of call, and size of file. The user may configure a different filter for each monitoring instance, hence providing added flexibility. The user has the option to display all Active Calls or a user-defined filtered list of all Completed Calls."

Mr. Kulkarni furthermore added, "Audio playback of completed and captured calls is easily accomplished with the CMU. A captured call can instantly be played to the PC speakers, either the East direction, or the West direction, or both directions simultaneously. The user may as well display the captured call to a waveform viewer for furthermore analysis."

The product line as well 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 product line complements all of GL's products. Using ITU-standard algorithms, GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks are all available. GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE (Long Term Evolution, latest standard in the mobile network technology) networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

The broadest range of simulation

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 just 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.

Wide variety of communications facilities

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 nearly any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.
