TW7000 Options
Remote-Control Capability
A variety of remote-control capabilities are offered. An extended front
panel control can be used as a: controller for short-distance
operation. Full-function remote control is available using either the
ISDN protocol (medium distances) or FSK tones (unlimited distances)
over any voice-grade 2- or 4-wire line. The TW7000 is also capable
of full computer control utilizing a variety of interface standards.
Dual ALE Capability Options
In addition to the widely used and cost-effective TRANSCALL
system, the TW7000 also offers a full FED-STD-1045 compatible
system which provides advanced features such as high-speed
scanning, sounding, link-quality analysis, and send/receive orderwire
message capability. Both of these ALE options provide selective
calling as well as "best-available-channel" selection.
DSP Voice Enhancement
The optional plug-in Digital Signal Processor (DSP) Voice
Enhancement option makes it possible to tailor the TW7000's
features and performance characteristics to a wide variety of
specialized applications.
High-Speed Data Option
The optional high-speed data option permits reliable transmission of
high-speed data, Group III FAX or video images, even under
uncertain HF propagation conditions. This option has been designed
to the U.S. MIL-STD-188-11 OA serial-tone protocol and provides up
to 4800 bps data-transfer rates (or 2400 bps with full-error
correction). When used in conjunction with the ALE option and the
TW9200 "DATACOM" Message Terminal, this integrated system
provides a cost effective, fast and reliable solution to long-distance
data communications requirements.
Encryption Option
These options provide either high-level digital encryption of both
voice and low speed data communications or medium level voice
scrambling.
