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 ar e stored in the temporary volatile RAM of the VF-1.

3.If no tones are detected within 15 seconds, a “B usy Tone” is sent to the host fax device.

4.Only a “Hang Up” from the host fax device will r eset 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.
