Use the code “55xx,” where xx is a number from 01 to 99 to get durations
from 100mS to 9900mS.
Note: Since each DTMF character is followed by a DTMF gap, be sure to add
the DTMF gap duration to the DTMF pause duration if you want an accurate
idea of the time between two DTMF pages.
Pauses are additive. A long pause may be created by placing a series of
pauses together within the DTMF page.
DTMF Custom Changes (Duration • Gap • Pause)
The following table shows DTMF Custom Changes affecting duration, gap, and
pause. it is generally related to preceding sections.
DTMF Custom Changes (Duration Gap

Control Character 9950
DTMF Custom Change Code Data Digit
custom DTMF duration change (10990mS) 50xx 0199 x 10mS
custom DTMF duration change (1009900mS) 51xx 0199 x 100mS
custom DTMF gap change (10990mS) 52xx 0199 x 10mS
custom DTMF gap change (1009900mS) 53xx 0199 x 100mS
custom DTMF pause (10990mS) 54xx 0199 x 10mS
custom DTMF pause (1009900mS) 55xx 0199 x 100mS
to ignore each custom DTMF change code enter 00 for xx in any of
above codes
DTMF-Related Notes
The DTMF decoder is turned OFF during DTMF pages to prevent the page
from being acted on by the controller. Since the DTMF encoder is shared
between the DTMF paging function and the DTMF autopatch function, there
may be a delay in paging while a number is dialed (or vice versa).
