3 Enter Yes to enable or No to disable in the DTMF Muting: field, or press
F2 (Choices) to select from a menu. Yes is the default.
Enter Yes to use dual-tone multifrequency (DTMF) muting to reduce false
DTMF recognitions. Such false recognitions sometimes result from the
network echoing back sounds that the voice system falsely recognizes as
touchtones.
Enter No when the interface is used for bridging; DTMF needs to pass
through without muting.
4 Enter the cable distance in feet between the Channel Service Unit (CSU)
and the voice system in the
CSU Distance: field, or press F2 (Choices)
to select from a menu. Valid values are 0–133, 134–266, 267–399,
400–533, and 534–666. The default is 0–133. If there is no CSU, the
value entered in this field should be the cable distance between the voice
system and the equipment to which it is connected.
5 Enter the desired wink time in multiples of 10 between 10 and 2550
milliseconds in the
Wink Time: field. The default is 230. This specifies the
length of the wink returned to the calling end on incoming calls.
6 Enter the desired post-wink delay, in multiples of 10 between 10 and
2550 milliseconds in the
Post-Wink Delay: field. The default is 80.
7 Enter the number of digits between 0 and 16 that the interface waits for
when receiving an incoming call in the
