The software has the ability to simulate an actual acoustic echo path with acoustic filter types, Echo path delays and losses; and features filter, attenuate, and delay to simulate a real acoustic environment.
The Acoustic Echo Compliance Test Software per G.167 and P.340 standards also conducts real-time as well as off-line analysis with tabular Pass/Fail results; simulate acoustic echo for Analog (Mobile Phone), digital (Gateway (News - Alert)), and Packet (VoIP IP Phone) applications; and conducts auto analysis of the response according to G.167 (03/1993) & P.340 (05/2000) requirements.
GL Communications defines acoustic echo as a common phenomenon that is encountered in many types of phone calls. Acoustic echo occurs when speaker output is fed back to the microphone input and this disturbs the far end speaker as they hear their own voice but delayed.
“GL's Automated Acoustic Echo Cancellation (AEC) Compliance Test Software is a feature rich application used to perform acoustic echo cancellation testing in accordance with ITU-T Specifications, G.167 and P.340,” said Robert Bichefsky senior manager of Product Development of the company.
By leveraging GL Communications' T1 E1 Analyzer products and the customers’ AEC hardware or software, the new software successfully performs Acoustic Echo Canceller testing.
“Automated AEC Test Software performs a full analysis (with detailed displays) that results in a "Pass" or "Fail”. Automated AEC testing concepts are implemented within the software for various End to End Applications (Mobile, TDM, and VoIP) scenarios,” added Bichefsky.
GL Communications was in news in August 2012 for unveiling its enhanced PacketScanWeb, a centralized IP and VoIP switch network monitoring system.
