Dispatch operation:
Key up and verify dispatch operation of the Model 748 on DCS 023.
Mobile-to-Phone operation:
Key up and send the DTMF sequence “*45”, unkey; the Model 748 will key up and issue the
Steering digit prompt
(default is simulated dial tone). Key up and enter a DTMF “*” or “9” for
phone line access. Hear dial tone back from the Central office. Dial a local phone number. You
should now be in the conversation mode. Key up and send a DTMF “#” for greater than 500 msec.
The Model 748 will send five short disconnect beeps and drop the transmitter.
Mobile-to-Mobile operation:
Key up and send the DTMF sequence “*45”, unkey; the Model 748 will key up and issue the
Steering digit prompt
(default is simulated dial tone). Key up and enter a DTMF “7” for Mobile-to-
Mobile access. The Model 748 will issue the
Overdial prompt
(default is an 925Hz beep tone). Key
up and overdial 01 (001 for Roamer). The Model 748 will now switch sub-audible encode to 100.0
Hz (our interconnect only user from the first example) and send ringing. Key up with 100.0 Hz and
send a DTMF “*” for greater than 500 msec to answer. The Model 748 will now switch to D023 for
encode. You are now in the conversation mode, radio to radio, with the Model 748 doing the proper
tone/code translation. When decoding 100.0 Hz it will encode D023; when decoding D023 it will
encode 100.0Hz. Key up with 100.0 Hz or D023 and send a DTMF “#” for greater than 500 msec.
The Model 748 will send five short disconnect beeps and drop the transmitter.
Phone-to-Mobile operation:
Call into the Model 748, when the line is answered the
Overdial prompt tone
will be issued (default
is an 925 Hz beep tone); overdial 45 (045 for Roamer), the Model 748 will key the transmitter and
start sending ringing tones and encoding D023. Key up and send a DTMF “*” for greater than 500
msec to answer. You should now be in conversation mode. Key up and send a DTMF “#” for greater
than 500 msec. The Model 748 will send five short disconnect beeps and drop the transmitter.
