Press Release: GL Releases Enhanced T1 E1 Analysis Software
Gaithersburg, Maryland, USA - May 10, 2007 - GL Communications Inc. announced today the release of T1 E1 Analysis
Suite Version 4.98 with new products and enhancements. Speaking to the media, Mr. Vijay Kulkarni, CEO of the company said, "The
T1/E1 Analysis Suite of products provide comprehensive analysis and emulation capabilities for voiceband analysis and signaling
protocol analysis. The additions to the T1 E1 Analyzer product suite now include a new product: MLPPP Emulator and Analyzer.
And a series of new applications: Automated Testing of Trau, HDLC, MLPPP, and CAS Simulator".
Mr. Kulkarni further added, "A host of new features and enhancements are also added to the existing applications and are: Trau
Traffic Monitoring feature in Trau PDA, Automated detection and capture of frames in Trau Analyzer, Bulk delay feature in error
insertion for (USB T1 E1 units only), MLPPP decoding capability in PPP analyzer, Automated Continuous Capture with profile loading
capability with file concatenation tool, Digital Audio Editor Tool integrated with Call Capture and Analysis Application (CCA), and
Calling and Called Party Number in ISDN emulator". And he told, "The Enhanced T1E1 Analyzer Product suite would add value to the
T1 E1 testing needs of the customers in general".
New product introduced to T1/E1 Analyzer - 4.98 is:
MLPPP (Multi-Link Point-to-Point Protocol) Emulator and Analyzer
GL's MLPPP Emulator simulates the Point-to-Point (PPP) and Multi-Link Point-to-Point (MLPP) protocols.
MLPPP bundles multiple link-layer channels into a single network-layer channel. Data sent through this channel will be distributed
among all the links. However, in PPP simulation, each link is separate and hence the Link Configuration, Action, Statistics, and
Impairment features can be set differently for each link.
Other new applications included with T1 E1 Analyzer's Windows Client Server are :
Automated Testing of TRAU (Capture/Playback TRAU Traffic using scripts)
The TRAU client-server module supports capture and playback of TRAU traffic using scripts. The functionalities supported in
TRAU client-server application are similar to HDLC Tx/Rx client-server module with additional TRAU broadcasting transmission and
multiple receive features per task.
Automated Testing of HDLC (Capture/Playback, Error Testing, Encode, and Decode HDLC Traffic using scripts)
HDLC Tx/Rx client-server module supports script-based capture/playback of HDLC frames in HDL files located on the server and
on the client. HDLC Encode/Decode client-server module permits encoding & decoding of HDLC streams of various bandwidth (hyper
channel, timeslot, and multiple sub-channel streams per timeslot). HDLC Error Testing client-server module permits transmission of
memory generated sequences of fixed or variable length HDLC frames, GL *.HDL Trace file frames, and various bandwidth streams.
The Channel Associated Signaling (CAS) Simulator is a client-side application that can be used to simulate and analyze any
user-defined CAS protocols by providing signaling bit transitions and forward/backward frequency tones/digits.
In addition to generating/receiving CAS calls, the CAS simulator also processes the receipt of Dialed Number Identification Service
(DNIS) and Automatic Number Identification (ANI) information.
Automated Testing of MLPPP (Error Testing, and Capture/Playback MLPPP/PPP Traffic using scripts)
Automated testing of PPP and MLPPP frames can be accomplished using MLPPP Tx/Rx client-server module. This module allow
users to use script based GL's clients or embed it into the user's test environment. Functionalities supported are sending MLPPP
frames with or without impairments, receiving MLPPP frames, and logging of the events.
Other significant features added to the T1 E1 Analyzer:
Bulk Delay feature in error insertion (For USB T1 E1 Analyzer Units only)
Bulk delay is an added feature in Error insertion application (applicable only to USB Analyzers) that allows users to apply delay
on the entire T1 E1 trunk (full multi-frame) of 1.544Mbps (T1) pipe or 2.048 Mbps (E1) pipe. Delay can be varied from 0 to 169.77mS (T1)
or 127.99mS (E1) with an accuracy of ± 10µs.
PPP analyzer now with MLPPP decoding ability
GL's PPP Analyzer can now be used to capture and decode a host of PPP as well as MLPPP protocols exchanged between the two
nodes over T1 E1 link.
User can obtain detailed analysis of the protocol and can perform various statistics measurements. The stream selection in MLPPP/PPP
analyzer is enhanced with the option of selecting multiple cards to capture the frames simultaneously in a single instance.
Automated Continuous Capture (ACC) with profile loading capability with File Concatenation Tool
The ACC application permits users to capture data (*.ala, *.ula, *.pcm, *.wav, *.ber) as seamless chunks in files of the specified
size, or up to the specified time limit of capture. The chunks of data captured in files can then be concatenated to one single file using
File Concatenation Tool, without missing out any data during the process. The settings during capture can also be saved and loaded
for another instance using T1 E1 analyzer's Save-Load Profile option.
Digital Audio Editor Tools integrated with CCA
The CCA application supports third-party digital audio editing and visualization tools such as Adobe Audition and Goldwave.
These digital audio editing and visualization tools can now be internally called by T1 E1 analyzer to view the captured files in either
stereo or mono modes.
These tools support variety of file formats including *.pcm, A-Law, Mu-Law, *.wav, and others.
Calling/Called party sub-address configuration in ISDN Emulator
The ISDN sub-address parameter is used to identify each device uniquely, when more ISDN devices are using the same line.
This new option in ISDN Emulator permits users to set the calling and called party sub-address on corresponding timeslots.
