Default Value:
P=0 (Tone Detection is activated on the line)
Notes:
1. If P is dialled as “0”, the system checks the tone on the lines to see if one of the
parties hang up. If the CO disconnect tone is received, the lines are dropped.
2. If P is dialed as “1”, the tone on the line is not detected even if both sides hang
up the phones; the line is dropped after 3 minutes.
