Primary Secure Fax
For the purposes of this document, a Primary
Secure Fax is any secure fax system employing
the 90si Secure Fax Gateway
Primary Non-Secure Fax
For the purposes of this document, a Primary
Non-Secure Fax is a COTS fax connested to
a 90si based system that can automoatically
answer incoming non-secure fax call, just like
all the other unclassified faxes you are familiar
with.
Protocol
Generally, a protocol is a set of standard rules
used to send data over a communications
channel. Specifically, secure faxes employ a
number of protocols including Mil-Std-188-
161 / STANAG 5000, SCIP Async and some
older secure fax protocols referred to Modified
Group 3.
PSTN
An acronym for Public Switched Telephone
Network, it refers to the commercial telephone
systems that carry the vast majority of non-mo-
bile telephone calls worldwide.
Public Fax
A document that does not contain sensitive or
secret information and, therefore, need not be
transmitted in a secure manner.
Red Data Port
The term Red Data Port refers to the RS-232
serial interface on the crypto device to which
the 90si's "STE" cable connects. It is also re-
ferred to simply as Data Port.
Ricoh / Compatibility Protocols
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. Also referred to as
Modified Group 3.
RS-232
Recommended Standard 232 is an industry
standard for the electrical interface between
communications equipment (such as the STE)
and communications terminals (such as the
90si).
SCCP
An acronym for Skinny Call Control Protocol
which specifies how an IP telephone instrument
connects to and operates with a Cisco Systems
VoIP call router.
SCIP
Secure Communications Interoperability Pro-
tocol (SCIP) is a new US, Allied and NATO
cryptographic architecture that is employed i
new Secure Telephones such as the STE/ECC.
SCIP Asynchronous Protocol
Commonly called the Async protocol, this rela-
tively unused secure fax protocol has become
the defacto standard due to the switch from
KOV-14 crypto cards to the new KSV-21.
SDD (Secure Data Device)
An SDD is a data only version of secure tele-
phone.
Secondary Fax
Secure Data Mode
A STU-III or STE’s secure data mode encrypts
confidential or classified information to be
transmitted and received over standard tele-
phone lines. It is this mode that secure faxes
are transmitted using.
Secure Fax
A secure fax is a document that contains con-
fidential or classified information that must be
transmitted in a secure manner. This term is
alternately used to describe the equipment used
to transmit and receive classified documents.
See Secure Fax Device below.
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.
Secure Only Configuration
This simplest of the 90si configurations allows
the attached fax to function as a secure fax and
only as a secure fax.
