Basic Operation of Store and Forward Mode
1. When the host fax device comes off hook, it is connected to an artificial line within the VF-1
and the dial tone is provided to the host fax device.
2. Any “Touch Tones” sent by the host fax device are stored in the temporary volatile RAM of the
VF-1.
3. If no tones are detected within 15 seconds, a “Busy Tone” is sent to the host fax device.
4. Only a “Hang Up” from the host fax device will reset the VF-1 out of this mode.
5. If at least one tone is detected and there has not been any additional tones for 3 seconds, then
the VF-1 seizes the phone line and dials the phone number string that has been pre-programmed
via #00.
6. After this stored pre-programmed number string is sent, the VF-1 monitors the phone line for
“Call Progress” if dip switch 3 is ON.
7. If dip switch 3 is OFF, after the stored pre-programmed number string is sent, the VF-1 waits
the time out period in programming mode position #40.
8. After this sequence of events, the VF-1 dials the stored phone number string that the host fax
device had originally dialed.
9. The last step is that the VF-1 allows the connection to the receiving fax device phone line.
10. From this point forward, the sequence is the same as the Straight Thru Mode.
NOTE: In either mode, the transmitting/receiving phone line will be restricted (relay contact opens in
the VF-1 for the phone line) if an attempt is made to transmit more pages than the amount of money
entered into escrow of the vending access controller (Raptor 2 or other vending control device) within
5 seconds of the last paid page sent.
