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 pressing

, then following the selection mode rules.
