5. Pseudo Ring Back Tone (PRBT): Fax / Tel Mode
This 400Hz, modulated by 16Hz tone is generated by the Modem and has a 1 sec. On and 2.6 sec.
Off interval. The Off time of Pseudo Ring Back Tone requires at least 4 sec. to detect CNG.

6. CNG Detection
The 1100Hz CNG signal is checked by the integration time of On-time and Off-time. If the On and Off
time of the detected signal is within a specified value, the signal is recognized as CNG. If it is not within
a specified value, the unit will re-start the CNG detection from the beginning.
