90si Reference Guide
1.0 Configuring your STU-III for the 90si
The most common cause of 90si operational problems are attributed to not having the STU-III's
Secure Data port configured for "Synchronous" operation. The following sections provide step-
by-step instructions for configuring various secure telephones for "Synchronous" operation as
well as setting "speed" and "duplex" to provide optimum performance with the 90si. The "Press"
column indicates which button on the secure telephone should be pressed. The "Display" column
indicates what the responding display will show. The first line indicates the state of the secure
telephone before proceeding.

2.0 90si Status LED's
There are two LED's located on the front panel of the 90si. The following three sections explain
what the various LED states indicate.
2.1 Power-up
Note: Before applying power to the 90si, make sure that all cables are securely connected and that
your commercial fax device is in Auto-Receive (Fax) mode and answers on 1 or 2 rings.
There are a series of LED indications during the 90si power-up sequence. Before power is
supplied to the unit, both LED's will be extinguished. When power is initially applied, the green
"POWER" LED will flash intermittently indicating that a self-test is in progress. Once self-test is
successfully completed, the green "POWER" LED will illuminate. The 90si is now in the "ready"
state.
2.2 Communication Errors
If an error occurs during a reception or transmission of a fax, the red "FAULT" LED will
illuminate. This indicates that a communications error has occurred. The unit will still operate.
The red "FAULT" LED will go out after 90 seconds or once a new transmission begins.
2.3 System Errors
Flashing green and red LED's indicate that the 90si has detected an internal failure during self-test
at power up, or during normal operation of the unit. If this occurs, press the white "RESET"
button located on the right side of the unit. This will restart the 90si and should return it to the
"ready" state (green "POWER" LED on, red "FAULT" LED off). If it does not, depress the
"RESET" button a second time. If this is ineffective, unplug the unit from the wall, wait a
moment, and plug it back in.
2.4 Contact GFS Customer Service
If all of these steps fail to return the unit to a "ready" state, contact Gateway Fax Systems'

90si Reference Guide
3.0 Glossary of Secure Facsimile Terms
Listed below are definitions of words and terms used in the 90si User's and Reference Guides.
Broadcast: A signaling option in the Mil-Std-161 mode in which the transmitting device does
not look for any acknowledgements during a fax transmission.
Commercial Fax Device: A Commercial-Off-The-Shelf (COTS) "standard" Group III fax
machine or computer-based fax device.
Dual Mode: A 90si configuration which allows the local fax machine to communicate with both
secure and commercial fax machines.
FEC: (Forward Error Correction) An option available in the Mil-Std-161 mode that can decrease
errors in fax transmission over noisy communication lines. Note that STU's provide "clean"
communication lines therefore eliminating the need for FEC.
Handshake: A signaling option in the Mil-Std-161 mode in which the transmitting fax device
looks for acknowledgements during a fax transmission.
Mil-Std-161: The SECDEF-mandated military standard protocol for digital data transmission
between fax devices. Mil-Std-161 is compatible with NATO's STANAG 5000 protocols.
Off-Hook: The state created on a telephone line when a telephone handset is picked up.
One-Touch Key: A feature on a fax machine that allows designated buttons to be programmed
to go "Off-Hook" and automatically dial a telephone number. In the case of the 90si, we
recommend that you program one of your fax's one-touch keys to dial a "1" and designate it the
"Secure Start" key.
Public Fax: A document that does not contain sensitive or secret information and, therefore,
need not be transmitted in a secure manner.
Ricoh / Compatibility: A set of digital protocols for communication between secure fax devices.
These protocols allow the 90si to be backwards compatible with older secure fax machines.
SDD: Secure Data Device. An SDD is a data only version of secure telephone.
Secure Data Mode: A STU-III's secure data mode encrypts confidential or classified
information to be transmitted and received over standard telephone lines. It is this mode that
secure faxes are transmitted using.
Secure Fax: A secure fax is a document that contains confidential or classified information that
must be transmitted in a secure manner.
Secure Fax Device: A specially manufactured fax device that includes the interface and protocols
necessary to communicate over secure telephones such as the STU-III.
STE: Secure Telephone Equipment. New secure telephone for use by the US Government.
STU-IIB: Secure Telephone Unit Generation Two Version B. NATO version of STU-III.

STU-III: Secure Telephone Unit Generation Three.
STU-IIIA: Secure Telephone Unit Generation Three Version A. US Secure telephone that can
connect with a STU-IIB.
