X-TEL Launches Voice Quality MOS Tool Based on ITU Standard PESQ

LOMBARD, IL. – November 9, 2004 – X-TEL Communications, Inc., a leading provider of engineering test systems and services for the wireless industry, announced the release of XQi, X TEL’s voice quality evaluation tool based on the International Telecommunications Union (ITU) specification P.862 PESQ. Perceived Evaluation of Speech Quality (PESQ) is the latest approved specification for evaluating the quality of voice over wireless phone calls. PESQ is a true international standard unlike other proprietary voice quality measurements that compare themselves to the PESQ accuracy. All X-TEL Xi systems can be upgraded to include these voice quality metrics. The unique X-TEL platform gives wireless operators the ability to test voice quality every day side by side with traditional metrics such as RSSI, Ec/Io, RxQual, BLER, etc. XQi fully supports single and multiple phone configurations for testing GSM and UMTS networks.

"Subscribers evaluate the wireless operators every day based on the quality of voice calls. Hence, voice quality should be measured on every test call, not just on a quarterly basis during system benchmarking exercises. XQi is the first tool that enables operators to test each and every day with their existing drive test systems," said James Richie, CEO, X-TEL Communications, Inc. XQi's portable configuration enables each field engineer to receive immediate feedback on perceived network quality while they optimize network performance. Automatic reports may be easily distributed to others within the organization via HTML. "XQi allows the operators to view the network from their subscribers' perspective on a daily basis," says Richie.
