DTMF Level
You must identify the individual lines that you do not want users to
access when they dial toll-restricted numbers. Do this by first
assigning the lines to toll groups and then assigning those toll groups
to the restricted number. There are 32 toll groups available for line
assignment. Assign one, several, or all lines to any desired toll group
or combination of toll groups as needed. See section 11 for complete
toll restriction programming details.
Adjust the audio level of the DTMF signals to a low (-5 db), medium
(0 db), or high (+3 db) setting. Certain sites may require a higher db
level to overcome line conditions that could interfere with reliable
dialing such as a long loop distance to the central office.
