Tone/Pulse/Inter-Digit Duration Selection

Description
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.
A longer tone duration or inter‐digit duration time will cause a slower output of
manual or automatic system‐dialed numbers.
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.
At default DTMF duration is set to 70 milliseconds.
Default Settings:
Dialing Ratio – Break Time = 60 ms (Range is: 60/67.)
Dialing Ratio –Inter‐Digit Time = 800 ms (Range is: 400‐800ms.)
Dialing Ratio –Tone Time = 70ms (Range is 70/90/120 ms.)
