4.1.1 Data Line Security

Description
Once Data Line Security is set on an extension, communication between the extension and the other party is
protected from signals such as Call Waiting, Hold Recall and Executive Busy Override. Extensions which have
devices connected to them such as modems or fax machines may set this feature to maintain secure data
transmission, by blocking tones or other interruptions during communication.

regardless of the originating extension (under contract with the telephone company).

Pulse to Tone Conversion
It is possible for an extension user to temporarily switch from Pulse mode to DTMF mode in order to access
special services such as computer-accessed long distance calling or voice mail services. To switch to
DTMF mode, wait for a preprogrammed time period (Default: 5 seconds) after the CO line is connected,
or press . This feature works only on CO lines set to Pulse mode. DTMF mode cannot be changed to
Pulse mode.
It is possible to select a pulse rate for the CO line port which has been set to Pulse mode. There are two
pulse rates: Low (10 pps) and High (20 pps).
It is possible to assign the minimum duration of the DTMF signal sent to the CO line port which has been
set to DTMF mode.
