1612-03: DP Interdigit Timer
Use this timer to set the duration of the Dial Pulse Interdigit signal (i.e., relay open time between
each digit). Set this timer for compatibility with the connected telco or PBX/Centrex. Keep in mind that
there are three components of a Dial Pulse digit: Make interval, Break interval and Interdigit interval. An
improper setting may cause misdialing.
