GateWay Fax Systems, inc.
2 .3 .7 1-Line Dual-Mode with an A/B Switch
This configuration is for use when the Commercial Fax will function as Either a Non-Secure Fax or a Secure Fax
but not both without an operator actuating the A/B Switch. Use this for "Nite-Mode" operation when you want to
receive unclassified faxes automatically when you are away.
For an Automatic Single-Line configuration see Section 2.3.6,
Set the Configuration to (03) 2-Line Dual-Mode. See Section 2.4, Setting Your Chosen Configuration, for in-
structions on how to do this.
A/B Switch Operation:
A: Unclassified Fax Mode – With the switch in the "A" position, incoming calls will ring the fax. The Secure
Telephone is disconnected and will not get dial-tone.
B: Secure Fax Mode – With the switch in the "B" position, incoming calls will ring the Secure Telephone. The
fax is disconnected and will not get dial-tone.

Setting Your Chosen Configuration
If you are using the Secure Only Configuration and your 90si is new from the factory, you need not set the config-
uration. If on the other hand your 90si is not factory new or you have chosen one of the Dual-Mode configurations
you will need to tell the 90si what configuration you will be using. This is done using DTMF tones from the FAX
dial pad while in the Default Settings mode. The configuration options and code numbers are shown below:
