Telephone-to-Tone-Only Pager Calls
The caller first gains access to the Model 748 (see “Call Setup (Telco)” earlier in this section). A
valid user number or ANI has been entered, the Model 748 has keyed the transmitter, any required
selective calling sequence (paging tones) will now be sent, the caller will hear one ring while the
paging tones are being sent. The caller will next hear a series of tones imitating the pagers alert
tones. The call is then disconnected automatically.
Telephone-to-Tone-and-Voice Pager Calls
The caller first gains access to the Model 748 (see “Call Setup (Telco)” earlier in this section). A
valid user number or ANI has been entered, the Model 748 has keyed the transmitter, any required
selective calling sequence (paging tones) will now be sent, the caller will hear one ring while the
paging tones are being sent. The Model 748 will then send the “speak your message at the beep”
voice prompt (prompt #6) followed by a “go ahead” prompt to the caller. Once the prompt is heard,
the caller may begin speaking, and the message is transmitted over the air. The message may be up
to the
Pager talk time in length or until VOX detection drops for three seconds. When the talk time
has expired, the Model 748 sends two “stop” beeps to the caller and disconnects the call.
Application note:
If a selective calling sequence is not required (no paging tones programmed), a single ring on the channel will be sent
instead.
