To provide an acceptable service to your carrier customers you must pass an answer supervision signal back toward their switch at the appropriate time. Technology Our Answer Supervision Generator will listen to the calls as they progress using digital signal processors to analyze the audible call progress events. At the point when it determines that a call has been answered a positive answer supervision signal is sent back towards the originating switch. The system can be configured to recognize the ring back, busy and congestion tones of any country's national telephone network. It also recognizes speech and fax tones.
Answer is declared based on a complex algorithm involving tone, voice and cadence detection.
See our white paper for more details. Configuration Typically global service providers will use channel banks to bridge the analog local lines to the digital equipment used to compress the traffic before putting it on an international leased line or the Internet. The Answer Supervision Generator is designed to operate on the digital lines interconnecting the compression equipment to the channel banks. For each channel bank the system must be equipped with two spans, one in and one out. The system can be built in T1 or E1 configurations supporting up to 8 channel banks per chassis.
