Introduction IMI 66-037
The system programming is electronically protected during an
AC
power failure by a battery-like device called a "super-cap".
The
stored program data will remain in memory for a minimum of 30
hours after AC power fails or is disconnected.
The system must
be powered continuously for at least 30 minutes prior to the
power failure or disconnection for memory preservation to occtir.
m_s.y $_a~ Field Station :(@pt.ion)

There is an optionally available 8-line telephone station
equipped with 14 visual indicators adjacent to the memory keys.
-This station provides all of the available features in addition
to a Busy Lamp Field (BLF) display.
The visual indicators of
this station display the status of the Direct Station Selection
(DSS) intercom stations provided by the system at the key
locations.
Call Announce With Handsfree Answerback
-..'-t -'G~--'.G--- -'i'-- --;-i'-'e-~.ei

The internal speaker at each station provides call-announce
capability over the intercom link.
A handsfree response to a
call-announce call can be made. This response is transmitted by
the microphone built into the handset.
Call Transfer
'- i - - 'A - - - i - 'i -
Call transfer allows incoming calls to be transferred from one
station to another,
via the intercom link, in one of two ways.
If both stations have access to the incoming line, a common line
pickup transfer can be effected.
If the other station does not
have access to the incoming line, transfer can still take place
using the system transfer feature.
Some transfer considerations
are as follows: If a transfer is attempted when there is no call
on hold, the station being transferred to will receive the
intercom dial tone, and the transferring station will he dropped
from the intercom line. If a transfer is attempted and the
station being transferred to does not answer the intercom call,
the transferring station will reconnect to the call.
Common Audi,ble and Auxiliary St.ation Interface
-.i---- ----I-- -c-k mm."-'-'--'- -w-'-s--..
.- '~.;.- _ _ " _ ^i'
Contact points are available which provide dry relay contact
closures whenever an incoming line rings and whenever station 17
rings.
The contact closures track the ringing pattern and can be
used to control an external signalling device.
When certain
station ports are programmed to function as
PA
ports, these
contact closures become enable contacts.
They close when the PA
port is called and can be used to enable an external PA system.
