Concurrent Operation of 4 Functions
The DTMF signal generator, DTMF signal detector, call progress tone generator, and call
progress tone detector can operate concurrently.
When both the DTMF signal generator and call progress tone generator operate concurrently, the
DTMF signal sometimes cannot be detected if the receive level of the DTMF signal is less than
-36 dBm.
