GL Launches Version 5.20 of T1 E1 Analyzer Products and Software

GL Communications, a company that provides targeted PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, recently announced the expansion of its T1 E1 Analyzer product line and software.

 

This announcement has added significant value to T1 E1 testing needs of customers.

 

The T1 (or T-1) carrier is the most commonly used digital transmission service in the United States, Canada, and Japan. It consists of 24 separate channels using pulse code modulation (PCM) signals with time-division multiplexing (TDM) at an overall rate of 1.544 million bits per second (Mbps). E1 is the European specification for the data transmission of 32 DS0 data streams.

 

GL Communications’ (News - Alert) T1 E1 Analysis suite of products provides comprehensive analysis and emulation capabilities for voiceband analysis and signaling protocol analysis.

 

In the latest version, the company’s GSM real-time and offline protocol analyzer supports decoding of proprietary 'Mobis' Interface (Motorola (News - Alert) equivalent of the GSM A-bis interface). This includes messages between BSC (Base Site Controller) - BTS (Base Transceiver Station) and BSC (Base Site Controller) - PCU (Packet Controller Unit).

 

Additionally, in the TRAU Protocol Analyzer & TRAU Traffic Playback, the Physical Link layer parameters in Statistics has been changed to include Device 3, Start/End Subchannels, Start/End Timeslots, Timestamp, Errors Code, Total sub channels and Timeslots per sub channel used.

 

GL’s SS7 Protocol Analyzer is also enhanced to support decoding of INAP CS2 (Capability Set 2) as per INAP CS2: ITU recommendation Q.1228, and INAP CS2 (ETSI (News - Alert)): EN 301 140-1 Specification.

 

Apart from this, enhancements added to the Window Client Server Application allow the Acoustic Echo Path Simulation using Dynamic DSP Operations. The application has also been enhanced with Scripted DSP commands that provide the ability to specify a sequence of digital signal processing steps to be performed on incoming and/or outgoing timeslots.

 

The WCS DSP Operation module also allows real-time as well as offline testing using DSP commands to perform functions such as Amplification/Attenuation, Delay, Filter, File Tx/Rx, Logical Operations etc.

 

GL Communications Inc. offers a complete line of T1/E1/T3/OC-3 Test Solutions. The company’s Ultra T1/E1/T3/OC-3 cards are used as the hardware platform for their PC-Based and Laptop-Based testing equipment.
