DTMF Stripping

DTMF tones recorded at the beginning of an audio message are typically used for zone control purposes.

A repeated page should not have the zone control tones on the front end of the second page because the

zone controller is already routed, therefore these tones will be stripped on any repeats of a page. Only DTMF

tones at the beginning of the page would be handled in this fashion. Any DTMF tones recorded in the

middle of the message would be recorded and played back in the typical manner.

DTMF Control

This setting determines how and where the DTMF tones coming from audio input, during a recording, are

processed. Tones can be stripped only at the beginning or in the middle of the message. If the tones are

stripped in the middle of the message, all recorded information preceding those tones will be deleted.

4 DTMF Control

UP At Start - Strip only tones preceding audio message (factory setting)

DN Anywhere - Strip any tones in message, and restart recording message

DTMF Allotment

This prevents unauthorized users from playing touch tones over the paging system. Most paging systems

require a limited number of tones to be recorded because of zone controlling equipment, but if a certain

number of tones is exceeded, the DFT120 will abort that particular recording. The number of tones which

the DFT120 can be programmed to cut off after is two, three, four, or unlimited.

Message Abort

This would allow the caller to abort a page directly. Should they not like the page they are recording, they

can press the “#” button two times within one second and the recording will immediately be aborted and the

busy back tone sent to the input. They can then call back and record another page. A single “#” sign during

the recording will not have any effect.

Configuration switch 9 activates or disables the Pre-Page Tone. If Pre-Page Tone is active, the tone is sent

to both the Override input as well as the output. Played before recorded message play back and during live

override announcement (heard in both speakers and on TEL line).
