11. DTMF DIALING BY RADIOS
11.1. MANUAL DTMF DIALING
Most radios will digitally dial a phone number with EDACS signaling. Some radios do not have a numeric keypad, but
do possess a DTMF microphone. The radio can be programmed with the DISA number which can be sent for interconnect
access. This number will result in dial tone returned to the radio, after which the radio will send DTMF tones using the
DTMF microphone.
• The number the radio sends initially will be the DISA number.
• The MD110 will return dial tone, then accept DTMF digits from the radio.
• This may result in unrestricted calling, except in the case where another PBX toll restricts the call.
11.2. RADIO TRANSFERRED DTMF DIALING
The procedure for manual DTMF dialing applies except if the radio is equipped with a keypad, radio digits may be
entered via the keypad followed by PTT to send the digits rather than using the DTMF microphone. In this case, the radio
must be programmed for DTMF pulse width and interdigit delay for the MD110 to correctly interpret the digits as specified in
the LBI-39000 DTMF radio programming section.
