the handset is lifted) or places the outside line on hold (if digits are dialed) and causes
intercom dial tone to return to the IST.
Pressing and releasing the hookswitch is commonly known as flashing the hookswitch or
performing a FLASH. Some ISTs are equipped with a TAP button, Users can press the
TAP button to cause the same effect as performing a FLASH.
The system provides a feature that allows IST users to FLASH an outside line for some
purpose (for example, to access a host system feature). Since flashing the IST hookswitch
while on an outside line accesses the intercom dial tone, users must dial a code to
actually generate the FLASH signal over the outside line.

Intercom Features

Automatic Callback
If a telephone user encounters a busy tone or a ring no-answer after calling an intercom
station, She or he can dial a special code number that will cause the system to
automatically ring both the user's telephone and the one that he or she was calling. This
automatic callback occurs after the busy station becomes idle or after the user at the ring
no-answer station takes some action at it that indicates to the system that it is available to
be answered. No class of service programming is required to enable this feature.
Call Announce With Handsfree Answerback
The internal loudspeaker at each station provides call-announce capability over the
intercom link. A user can make a handsfree response to a call-announce call without
lifting the handset.
The user can use the MUTE button to block all handsfree answerback response. This
arrangement will prevent a station user from monitoring another station site using the
monitoring ability of the voice announce feature. When a user presses the MUTE button,
all handsfree answerback is disabled thus inhibiting any off-site monitoring. The MUTE
light turns on steady to indicate that this feature is active.
Dual Intercom
This feature provides for two separate intercom lines at the same station. One intercom
line is fixed and is accessed with the Intercom button. The other intercom line is
programmable and is accessed by a programmable button selected for that purpose by
class of service programming. Calls are handled on the intercom lines in much the same
manner as outside calls are handled using the line buttons.
Special considerations are as follows:
• Distant party hang-up causes intercom link to drop.
