Tone / Pulse / Inter-digit Duration Selection

Depending on the outside plant environment, type of Central Office, and customer's specialized dialing requirements,
the DTMF "on" time (Tone) and Pulse Dialing – Pulse Time and Pulse Dialing – Inter-Digit Time for manually dialed or
system automatically dialed digits may be modified. Typically, no modification is required however, in some
installation environments where outside plant equipment is becoming antiquated or line conditions are poor, tone
duration and/or inter-digit duration timing may be increased to offset these poor conditions.

Conditions
a) A longer tone duration or inter-digit duration time will cause a slower output of manual or automatic system-
dialed numbers.
b) A longer DTMF "on" time and/or inter-digit tone time can be used to ensure more reliable interaction with
remote voice mail and similar remote DTMF dial pad actuated devices.
c) At default DTMF duration is set to 70 milliseconds.
Default Setting
Call Handling – Dialing Ratio – Break Time = 60 ms (Range is: 60/67.)
Call Handling – Dialing Ratio –Inter-Digit Time = 800 ms (Range is: 400-800ms.)
Call Handling – Dialing Ratio –Tone Time = 70ms (Range is 70/90/120 ms.)
