Card Networks Certifying CFN III Appendix F: Dialout Communications
An on light is shown in lowercase letters. Figure 32-2 shows how the modem looks when the
site first reboots and before the network handler task initializes the modem.

When the CFN3 application initializes the modem, the SD (Send Data) and RD (Read Data)
lights should flicker. These indicate when data is being sent or received by the site.
After the modem is initialized, the lights should look as in Figure 32-3 . Every few seconds, the
RD and SD lights should flicker. If this is not happening, the network software may not have
been initialized and the network handler is stopped until this step is done. Refer to the specific
Debit/Credit manual for setup information for your router.
If the AA (Auto-Answer) light is on, the modem has not been initialized for network
communications. Also, check the port setup. The host modem might be connected to the
remote CFN port.

When the network software is set up and running, the RD and SD lights flicker every few
seconds. When an authorization is attempted, if the speaker is on you should hear tones
indicating the modem has been given a number to dial. The OH (Off-Hook) light should go on
(
Figure 32-4 ).

If a good connection is made, the CD (Carrier Detect) light will go on.
Most networks have a setup time called Carrier Wait Timeout. If this is set too short, the site
will hang up before carrier is detected, which should take less than 20 seconds. Twenty
seconds is the default setting. If the CD light as shown in
Figure 32-5 does not come on, set
this parameter to a larger value and try it again. The modem may be slow in matching the
carrier signal with the host on the other end. If you listen to the modem, you will hear a digital
tone; when the tone shifts, the modem is attempting to sync up with the host. If a carrier signal
is detected by both, the light goes on.
New modems with 14400 and 28000 baud speeds may take several seconds as they “down
shift,” trying to match the host modems which typically run at 1200 and 2400 baud. This is
why GASBOY recommends a Hayes 2400 baud modem, even a used one. The connections
will be faster.
