4 Switch Interface Administration Digital Interfaces

3Enter 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.

4Enter 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.

5Enter 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.

6Enter the desired post-wink delay, in multiples of 10 between 10 and 2550 milliseconds in the Post-Wink Delay: field. The default is 80.

7Enter the number of digits between 0 and 16 that the interface waits for when receiving an incoming call in the Max. Digits in Called Number: field. The default is 4.
