May 16, 2008 -- GL Communications Inc. announced today the release of T1 E1 Analyzer Software Version 5.11 with new applications and enhancements. In a statement to the press, Mr. Vijay Kulkarni, CEO of the company said, "Our 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 new applications: SS7 and ISDN Protocol Decode Agents that permit remote real time monitoring and analysis for network wide applications. A very large SS7 and ISDN network can be easily monitored with this protocol decode agents and integrated into existing third party applications."

Mr. Kulkarni added, "There are also significant enhancements introduced to existing applications: Protocol Analyzers, Multi-Class ML-PPP Emulator, ISDN Emulator, and Digital Echo Canceller."

A brief summary of the new applications in the T1E1 Analyzer - 5.11 Release are provided below:

WCS SS7 Protocol Decode Agent

The SS7 Protocol Decode Agent module monitors SS7 links, captures frame header information, decodes multiple SS7 protocol standards, filters user-specified protocol parameters, builds call detail records(CDRs) and streams the decoded fields and/or CDRs to the comma delimited files (CDR.CSV and/or FRAMES.CSV) over TCP/IP to remote site. It can also capture filtered data in real-time using layer filter and field filter keys.

WCS ISDN Protocol Decode Agent

The ISDN Protocol Decode Agent module monitors ISDN links, captures frame header information, decodes multiple ISDN protocol standards, filters user-specified protocol parameters, builds call detail records(CDRs) and streams the decoded fields and/or CDRs to the comma delimited files (CDR.CSV and/or FRAMES.CSV) over TCP/IP to remote site. It can also capture filtered data in real-time using layer filter and field filter keys.

Other significant enhancements were introduced to the following applications:

Protocol Analyzers

Significant enhancements have been introduced to the protocol analyzer product series. User can now add hyper channels with discontinuous (sparse) timeslots. For example, a PPP link on card #1 can have timeslots 1 to 15 and 17 to 31 (#1:1-15, 17-31). Similarly, any number of hyper channels can be build with such various combinations.

The GUI part of the application that helps for protocol configuration now includes feature to edit decode parameters in *.ini file. This feature is now available for SS7, CDMA, CDMA on ATM, PPP, TRAU, and UMTS protocol analyzer decode engines.

With Inverse Multiplexing in ATM (IMA) feature, two or more T1 circuits can be configured to form a high-speed connection of DS3 circuit. ATM cells are transmitted across multiple interfaces in a cyclical fashion, and recombined to form the original stream. The ATM, CDMA on ATM (A3 A7), and UMTS protocol analyzers now support decoding with the IMA option.

Multi-Class MLPPP Emulator

User can add hyper channels with discontinuous (sparse) timeslots. NCP Configuration in PPP simulation allows selecting NCP parameter per link. The NCP status column in PPP view shows NCP layer status per link in PPP simulation. In MLPPP simulation, it shows the status of the entire MLPPP bundle.

Payload Traffic Generation, Reception, and Verification now supported in PPP and MLPPP simulation. Network Traffic is included as a new traffic source type in both PPP simulation and MLPPP simulation. MLPPP Emulator can transmit and receive Ethernet traffic over T1 E1 links by operating either in bridge or router mode.

ISDN Emulator

The emulator now allows the users to set various release causes during simulation. These include rejected, no user response, user busy, congested, and so on for disconnection of the particular call on the channel. At the termination end, after the call is terminated, the cause for disconnecting the call gets displayed in the Last Cause field.

Digital Echo Canceller (DEC)

The Digital Echo Canceller is a four-port software that supports bidirectional voice traffic between the two ends of a connection is now supported with logging option that allows to save file in *.CSV format as well as *.txt format.
