With POLQA, EXFO enhances support for VoLTE quality assessment metrics, allowing service providers to gain increased confidence when transitioning to VoLTE

QUEBEC CITY — EXFO Inc. (NASDAQ: EXFO, TSX: EXF) today announced the addition of Perceptual Objective Listening Quality Assessment (POLQA) to its market-leading BrixCall product line. POLQA is the newest voice quality measurement technique standardized in P.863 by the ITU-T.

With Voice-over-LTE (VoLTE) entering commercial deployment phase, service providers are looking forward to capitalize on premium services such as high-definition (HD) voice. The high-definition market is extremely demanding and service providers need to assure at all times that high fidelity impairment-free voice is actually being delivered. POLQA allows for true customer experience analysis of HD voice services.

POLQA provides superior measurement of common voice and HD voice quality impairments such as loss of fidelity, speech clipping, unacceptable noise levels, transcoding errors, excess latency and echo. POLQA support will be added to EXFO's market leading BrixCall product line. BrixCall is an advanced active testing and live call signaling and media analysis application providing comprehensive visibility into the performance of VoIP, VoLTE, IMS rich-media and video call traffic.

"By leveraging POLQA to validate end-to-end call quality, service providers are assured that their new HD voice services are delivering the enhanced quality that's expected," said Claudio Mazzuca, Vice-President of EXFO's Systems and Service Assurance Division. "The introduction of POLQA-in addition to our recently announced availability of VoLTE/IMS monitoring and troubleshooting functionalities such as live VoLTE traffic generation and the direct performance monitoring of critical IMS core elements-asserts EXFO's leadership in VoLTE testing and service assurance, and gives our BrixCall product line a further edge for present and near-future network deployments."
