Tone Detection Bandwidth:
When two lines are connected to each other (the line-line connection) or external
call diversion facility or Automatic Dialer is activated on the system, the system can
be set to detect the tones on the lines at the time of hanging up of talking parties or
of the tones on the lines to active automatic dialer.
The lower and the upper frequency limits of the tones to be detected can be
programmed by this code. These limits are also used for tone detection in Auto
Dialer facility.
8 7 7 6 4 0 5 L H
Parameters:
L
: 01 - 29
The index for the lower frequency limit. (It defines the
lower frequency that the system can detect when the tone
detection is made through the line-line connection,
automatic dialer or external call diversion)
H
: 02 - 30
The index for the upper frequency limit. (It defines the
upper frequency that the system can detect when the tone
detection is made through the line-line connection,
automatic dialer or external call diversion)
Default Values:
L=7, H=10
Notes:
1. Dialing 8776 4 05 * sets the indexes as their default values.
2. The value of H must be bigger than the value of L.
