DTMF Overdial / Conventional Mode Telephone
Interconnect
Once the radio has established a connection to the
public telephone system, it may be necessary to "over-
dial" more digits to access banking services, answering
machines, credit card calls or other types of systems that
require DTMF (Dual-Tone Multi-Frequency) access dig-
its.
Overdial operation can also be used to initiate a
telephone interconnect call via DTMF signalling if a dial
tone has already been accessed on the system. This is
the method that is used for making a telephone intercon-
nect call while operating in the conventional mode but
will also function in trunked mode if a dial tone is directly
accessible.
Telephone numbers and other number sequences for
overdialing can be stored in the phone list when program-
ming the radio. These numbers are accessed by press-
ing
M
, then following the selection mode rules.
In half-duplex mode, only one person may talk at
a time. The radio PTT button needs to be pressed
in order to communicate to the individual called
and released for the individual called to be heard.
