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 unveiled its Automatic Voice Enhancement Device Compliance Testing Solutions Per G.160 and G.169.
“The Auto VED Test Software is a feature rich application that uses GL Communications' T1 E1 Analyzer products to perform Automated Voice Enhancement Device testing in accordance with G.160 and G.169 ITU test requirements,” said Vijay Kulkarni, CEO of GL Communications, in a statement.
Kulkarni said that there are two methods of testing voice enhancement devices, and these are: file based approach, and real-time approach.
He said that the file-based approach method transmits files to Sin and Rin of the VED and captures responses at Sout and Rout.
Kulkarni said that with this method, the Sin is pre-created from the Rin signal. This method assumes that Rout is identical to Rin.
This, he noted, works perfectly for TDM-based Line Voice Enhancement Devices. This could also be used to test VEDs within Gateways in VoIP or VoATM environments as long as the delay between gateways is constant and Rout=Rin is valid.
“When testing VEDs within Gateways, a configuration of back-to-back Gateways is necessary to access the TDM side of each Gateway (News - Alert). The Real-Time Approach method creates Sin in real-time from the Rout. It is applicable to TDM, VoiP, and VoATM Networks. Windows Client Server (WCS) Software is used to perform real-time functions,” said Kulkarni.
TMCnet in November reported that GL Communications has announced the availability of its T1 E1 Voice Call Management utility software that provides complete call records for each captured file.
Earlier in the same month, GL Communications had launched an advanced CPE (Customer Premises Equipment) based VoIP monitoring reporting and diagnostic appliance called PacketProbe.
