4.0 If There's a problem

4.1 How Will You Know

The 90si Front Panel LED's
If the 90si encounters a problem during fax communication, the red "FAULT" LED on the front panel will illu-
minate. If this occurs, there is no need to reset the unit. The indicator will extinguish automatically.
Indicators On Your Fax Machine
Additional error indications may be displayed by your fax machine. These will usually be in the form of an
audible alarm (a "beep") or visual indicator (a light or alpha-numeric display). Consult your fax machine user's
manual for explanations of alarm conditions and how to restore normal operation.

4.2 Troubleshooting Tips

There are a number of places from which a problem could orriginate, including the COTS fax settings, the 90si
settings and wiring and the settings and wiring of the local cryptographic device. We will address common issues
below:
Fax Auto-Answer
Insure that the fax is set to automatically answer, as a fax, on the fewest # of rings possible (3 rings max). The
way this is indicated will vary by machine -- some have an "auto answer" button and/or light that should be illu-
minated; others might say "fax" in the display (not "fax/tel or TAD, etc.) and usually have a button called "answer
mode" (or something like that) that when depressed, cycles the machine through "fax", "manual", "tel/fax" and
"TAD". If you are unsure of this setting for your machine, call or email us and we will help you figure it out.
90si Configuration
The 90si comes from the factory set to the Secure Only configuration. This is the simplest and safest configura-
tion. Insure that your 90si is wired in the way demanded by the configuration your 90si is set for.
Secure Data Mode
Your STE (or other crypto device) needs to be set for Async 9600 (for most applications). Please insure that this is
the case. If it is not set properly for the default or one-time protocol you are using, the secure fax transaction will
fail.
Interconnect Cables
Insure that all of the cables that connecte to the COTS fax, 90si and Secure Telepnone are seated properly. It
might be a good idea to remove each of them, one at a time, and re-seat the connectors.
Make a Copy
This is an easy test that exercises much of the electronics and all of the mechanicals of the fax machine. If it does
not make a copy properly, then the problem is in the fax itself.
Place a Call on the STE or Secure Phone
Do you get a dial-tone and can you call and talk with another STE or Secure Phone in Secure Voice mode? Can
you transition the call into the Secure Data mode?
