DTMF Tone Stripping Method
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 of the
message or at the middle of the message.
If the tones recorded page are stripped in
the middle of the message all recorded
information preceding those tones will be
deleted, resetting the message start.

*Strip only tones at
the start of a recorded
page.
Strip any tones in
message and restart
recording message.
DTMF Allotment
Most paging systems
require a limited number
of tones to be recorded
because of zone
controlling equipment. If
the selected number of
tones is exceeded the
OPM-3SM will abort that
particular recording.

# # Abort
This would allow a caller to abort a page being recorded
by pressing the “#” button two times within one second.
The recording will immediately be aborted and the busy
back tone sent to the input. A single “#” sign during the
recording will not have any effect.

Pre-page Tone
A pre-recorded tone can be output prior to message
playback. This is used to alert listeners that a message is
about to be played. This tone will be output before each
message in the playback queue but not before the
repeated plays.

Number of Plays
The number of times which each message plays
during the playback sequence. If multiple messages
were recorded into the queue, each message will
play this number of times.

Record Activation Method
The method with which the
user will enter the record
mode.

*Off Hook(Loop Current) - The
system will record when the
system senses loop current
Audio Sensor - The system will
start recording when the audio
sensor goes active and will
stop when the audio sensor is
inactive for 3 seconds.
DTMF - The system will start
recording when it detects a
valid DTMF tone and will stop
when the audio sensor is
inactive for 3 seconds.
Not in use
NOTE: Record Input activation is always available regardless of switch
settings. A maintained contact closure on
any channel’s record input will
start the recording process on that channel for the duration of the closure.
DTMF Tone 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 the repeat of
a page. 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.
