GL Announces Satellite Channel Test, Simulation, and Measurement Products at Satellite 2008!

Gaithersburg, Maryland, USA (SANEPR.com) February 21, 2008 -- GL Communications Inc., announced today its Satellite Channel Test, Simulation and Measurement products at Satellite 2008, a leading conference and exhibition for the satellite communications community. Speaking to the media, Mr. Vijay Kulkarni, CEO of GL Communications Inc. said, “GL offers test tools to analyze and simulate satellite channels across various interfaces. These include Analog 2-Wire, Analog 4-Wire, Ethernet, T1, E1, IP, T3, E3, OC-3 / STM-1, and OC-12 / STM-4”. He added, “The applications include: Testing GSM backhaul over satellite, BER testing across all satellite gateway interfaces, Satellite delay and error simulation, Voice quality testing, Round-trip and one way delay measurement, Echo simulation and echo cancellation testing”.

Mr. Kulkarni, specifically mentioning about GL Communications presence in the event said, “GL Communications Inc is located at Booth #734 at the Washington Convention Centre, Washington DC with their Satellite Channel Test, Simulation, and Measurement products and services on display. And told this would help the conference delegates to appreciate the latest in Satellite Testing Solutions”.

About GL Communications Inc.

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards and solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (HDLC, ISDN, SS7, CAS, GSM, GPRS, CDMA), and with capacities up to thousands of channels.

GL’s VoIP products generate / analyze thousands of calls simultaneously with traffic types such as voice files, digits, tones, noise, and fax using G.711, G.729, AMR, EVRC, and GSM codecs. Additional features include visual analysis, real-time listening, recording, and voice quality assessment using ITU algorithms PAMS, PSQM, and PESQ.

GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and CDMA 2000 networks. Connections can be made to any wireless phone with automated call control, GPS, mapping software, and real-time signal measurements.

GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160. Network Surveillance and Monitoring products include Probes for TDM, VoIP, ATM, and Wireless networks.
