Press Release GL Begins Development of a Nation wide Digital (T1) Line Monitoring, Test, & Diagnostic System for the United States Postal Service

Gaithersburg, Maryland, USA - Februray 28th, 2006 - GL Communications Inc., a leading provider of test and measurement solutions for TDM, VoIP, and Wireless networks, announced today the start of a nationwide deployment of a Digital (T1) Line Monitoring, Test, and Diagnostic System for the United States Postal Service (USPS).

GL's solution for USPS features an instant overall view of the health of the entire network with the ability to successively drill down to individual T1 lines. Maintenance engineers can securely access the network view from literally "anywhere" that Internet access is available. They can also monitor, diagnose, and troubleshoot any T1 line remotely with simple to use scripts. The system can also monitor USPS's "Ethernet" traffic at all USPS hub locations.

Vijay Kulkarni, CEO of GL Communications Inc., explained "USPS's large network required us to clearly present clarity at different network levels. Our solution has a "rolled up view" of the entire T1 network. This view shows problems immediately but permits a detailed revelation down to individual T1 lines if desired. Our T1 probes are also capable of analyzing the content of the T1 lines, if USPS should need to in the future."

Other features of the T1 Line Monitoring, Test, and Diagnostic System include fail-safe operation during power disruptions or element failure, a central database for historical performance data, USB controlled passive / intrusive T1 switches, T1 probes for monitoring and intrusive testing, TCP/IP communication to a central collection station, and a secured database and Web server accessible via the Web. Any authorized PC with an Internet browser can access the Web server to obtain status of USPS's network or perform diagnostics on T1 lines - all remotely.
