DTMF Telephone Interconnect

DTMF Telephone Interconnect

Dual Tone Multiple Frequency (DTMF) tones are encoded by the radio to dial into (access) the landline telephone network and return (deaccess) to conven- tional radio operation.

Once the telephone network has been accessed, phone numbers can be dialled either manually or from memory. The keypad provides support for DTMF digits 0 to 9, and the characters A, B, C, D, ∗ and #.

NOTE

The radio is capable of storing a maximum of 9 pre- programmed phone numbers (up to 12 digits each).
