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 digits. 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 interconnect
call while operating in the conventional mode but will also func
-
tion in trunked mode if a dial tone is directly accessible. Tele
-
phone numbers and other number sequences for overdialing can
be stored in the phone list when programming the radio. These
numbers are accessed by pressing
m
, then following the
selection mode rules.
The following steps are required to dial these numbers:
1.
Follow the procedure in Sending A Telephone Interconnect
Call (Trunked Mode Only) to establish a connection to the
telephone system or consult the system administrator for
the procedure to access a dial tone on the trunked or
conventional system.
