IST-2
The IST-2 is a 50-line-button desk/wall-mounted telephone instrument that serves as the user interface to Raytheon
digital switching systems. The IST-2 provides the user with a consolidated secure/non-secure communications
device allowing access to all of the switch resources from a single instrument. This eliminates the need
for the user to have to remember particular operational nuances of a communications device.
The IST-2 telephone instrument connects to a switch via a twisted, shielded pair of wires and communicates
digital voice and data. In addition to voice and data, the phone is able to activate functions of the switch, and the
switch is able to control visual and audible functions on the phone. After manual call setup and activation, the
data port will support up to 57600-baud full-duplex serial data communication (some switch limitations apply).
The IST-2 supports line-key (button) expansion with the connection of up to two 80-key Line Expansion (LE-80) devices. Switch configurations may limit the number of LE-80 Line Key Expansion Units that may be connected
to each IST-2.
The Integrated Services Telephone (IST-2) main instrument is a top-mounted user interface keyboard, display,
and handset. The handset is connected to the main instrument with a coiled cord. In addition to the handset, the
unit contains an internal speaker and microphone to allow hands-free voice communication when authorized.
The IST-2 has two line-interface ports to allow simultaneous connections to both a secure and a non-secure
switching system. The unit has an auxiliary audio port for the connection of an additional audio device (handset,
headset, recorder, etc.) and an auxiliary data port for the communication of serial data. The IST-2 also has a
PCMCIA port to allow for future feature enhancements.
