GateWay Fax Systems 90SI manual Secure Only Configuration Recommended, Dual Mode Considerations

GateWay Fax Systems, inc. Model 90si Secure Fax Gateway User's Guide

2.3.1Secure Only Configuration (Recommended)

This factory default configuration allows the attached COTS fax to function only as a secure fax. If you wish to process Public or Uncalssified documents as well; see Section 2.3.2 "Dual-Mode Considerations."

If your 90si is factory fresh, it is already pre-set to operate in this mode. If it has been in another location or you are unsure of the current setting, set the Configuration to (01) Secure Only. See Section 2.4, Setting Your Cho- sen Configuration for instructions on how to do this.

2.3.2Dual Mode Considerations

We define Daul-Mode as any 90si configuration that allows the COTS fax to directly access an outside line, around the Secure Telephone, thus enabling the transmission and reception of unclassified faxes. The differienta- tion between sending a document using the Secure Phone's Secure Data Mode (a secure fax) and sending that same document to a non-secure fax is procedural. Therefore, if your 90si is configured for Dual-Mode, an un- trained operator could compromise a document. It is for this reason that the 90si is factory set to the Secure Only mode.

If untrained (regarding the 90si) people have access to your secure fax location, use the Secure Only Configura- tion and have the users go elsewhere for unclassified faxes. If, on the other hand, a limited number of people have access to the 90si, and they can all be trained on safe 90si operation, then one of the Dual-Mode configurations may be approprite for the location.

If you wish to use your 90si system for both secure and non-secure (unclassified) fax documents choose one of the the following dual-mode configurations.
