Integrator's Reference Manual for Polycom HDX Systems
DTMF Dialing
The Polycom HDX 9000 series systems generate the following tip/ring signal levels:
● Low-frequency tone: -10.2 dBV, -8.0 dBm when AC termination of the line is 600 Ohms
● High-frequency tone: -8.2 dBV, -6.0 dBm when AC termination of the line is 600 Ohms
● The system seizes the line and waits 1.5 seconds. The number is then dialed with a 80 ms tone period
followed by a 80 ms silence period for each digit.
