90 Glossary
Listed below are denitions of words and terms
used in the 90si User’s and Reference Guides.
Asynchronous
Async for short, Asynchronous refers to the
way in which data is passed between the 90si
and the attached Secure Phone. Specically,
no physical "clock" signal is generated by the
Secure Phone. Instead, the timing data is em-
bedded in the data and must be decoded by the
90si and the far end secure fax.
Broadcast
A signaling option in the Mil-Std-188-161
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) “stan-
dard” Group III fax machine or computer-
based fax device.
Conguration
For the purposes of this document, Congura-
tion refers to the various ways in which the
90si can be connected together with the fax,
secure telephone and outside phone line to
provide differing sets of secure and non-secure
fax and voice functions. See also, Secure Only,
1-Line Dual-Mode and 2-Line Dual-Mode.
Data Port (see also Red Data Port)
The term Data Port refers to the RS-232 serial
interface on the crypto device to which the
90si's "STE" cable connects. It is also referred
to as a Red Data Port.
Dual Mode
A 90si conguration which allows the local fax
machine to communicate with both secure and
commercial fax machines.
ECC
The KSV-21 ECC (Enhanced Crypto Card)
used in the STE, contains the SCIP crypto-
graphic engine.
FEC (Forward Error Correction)
An option available in the Mil-Std-188-161
mode that can decrease errors in fax transmis-
sion 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-188-161
mode in which the transmitting fax device
looks for acknowledgements during a fax trans-
mission.
KSV-21
The KSV-21 Enhanced Crypto Card contains
the cryptographic engine for the STE. The
KSV-21 does not support synchronous modes
with the STE connected to the PSTN.
KOV-14
The KOV-14 Fortezza Plus Crypto Card is out
of production, replaced by the KSV-21 and will
no longer function after 31 DEC 2009. When
installed in a STE, the KOV-14 allowed the
STE to communicate with the installed base of
STU-III's.
LED
An acronym for Light Emitting Diode, this is
the type of indicator lights used on the 90si.
Mil-Std-188-161
The SECDEF-mandated military standard pro-
tocol for digital data transmission between fax
devices. Mil-Std-188-161 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-Line Dual-Mode Conguration
This conguration allows the attached fax to
function as BOTH a secure fax AND a non-
secure fax. An operator must be present to
receive an unclassied fax.
One-Touch Key
A feature on a fax machine that allows desig-
nated 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
