GL Communications (News - Alert) Inc., a major player in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, has enhanced software tool, GLInsight, which helps in post processing of fax and modem calls.

“GLInsight is a state-of-the-art system that provides promptly processed information and analysis of data collected on IP and PSTN networks. Decoded results are analyzed on a per-network basis,” said Robert Bichefsky, senior manager for product development of the company, in a statement.

“Alternatively, data from two networks can be combined to provide additional insight into the networks’ behavior. It has a Windows-based user-friendly GUI which supplies the developer with varied and valuable information. Results files and transmitted graphics, signal level, and signal quality are just a few of the diagnostic tools provided,” said Bichefsky.

GL Insight, he said, enables the decoding and analysis of pre-recorded modem and fax transmissions. The transmission signals can be recorded from PSTN or IP media. It is a unique system used by developers of modem and fax technology, often in interoperability labs.

Bichefsky said that GL Insight can be used during the development and deployment phases of the products that support fax and modem transmission.

“It receives the recorded modem or fax transmissions in one of the two ways: As raw signal files (PCM files) – in either mono or stereo format, As IP capture files - created by capturing devices or by software,” said Bichefsky.

GLInsight demodulates the raw transmissions and presents the decoded data in an easy-to-understand format. It produces extensive log files with all relevant debugging information for easy event tracing, which in turn provides insight to potential sources of problems, Bichefsky said.

TMCnet in February reported that GL Communications has unveiled its software for Echo Performance Testing and Verification.
