(3) If station 20 is busy in a conversation,
override tone (128 Hz for 500-ms) will be
heard by the talking parties before the override
station is bridged onto the conversation. The
overriding station does not hear the tone.
(4) If station 20 is in the DND mode, or had
become idle while OVRD is being activated,
station 10 will hear ringback and station 20 will
be rung.
(5) If station 20 was being called, i.e. by station
30 but has not answered, station 30 will
hear the override tone while 10 will enter the
connection and hear ringback. When station 20
answers the three parties will be connected.
REMOTE ANSWER
4.22
Remote Answer (REAN) permits one station
to answer any incoming calls intended for
another station while the call is in the ringing
state. Calls cannot be remotely answered under
the following conditions:
•
A call to a station that has answered
•
Calls to a nonstation code such as paging
access or CO/PBX line access unless CO/PBX
call is in the ringing or hold state.
•
A call-forwarded call where the call has
been answered by the alternate station.
Call intercepts attempted under the above will be
routed to error tone.
4.23
REAN is accomplished as follows:
(1) If station 20 is in the ringing state and
station 10 wishes to answer the call, station
10 dials 07; and after the second dial tone is
received, dials 20-the code of the station to be
answered.
(2) If the feature is properly activated, station
10 will be immediately connected to the
calling party. At station 20, the intercom lamp
will flash the same as for a regular call and
station 20 can enter the call at any time. No
audible signal is received at station 20.
(3) The REAN feature is on a one-call basis,
that is, only the one incoming call in progress
ISS 1 , SECTION 5 1 8-4 1 1 - 1 00
will be intercepted, therefore, the feature does
not have to be canceled.

OPERATION-OPTIONAL FEATURES
FOUR LINKS
5.01
The basic 6B KTS is furnished as a two-link
system. To add the third and fourth link,
a second 487A KTU must be separately ordered
and installed in J5.
TOUCH-TONE SETS
5.02
TOUCH-TONE sets require the addition of
a 489A KTU to the system installed in Jl.
With the 489A KTU installed, the system will
recognize either rotary or TOUCH-TONE signals.
HANDS-FREE ANSWER ON INTERCOM
5.03
This feature requires the addition of a 2A
transmitter-receiver adjunct at each station
desiring the feature. HF AI permits a calling station
to voice-signal an HFAI-equipped station and also
allows the HF AI station to answer without going
off-hook.
In addition to equipping the desired
stations with an adjunct, the continuous ring option
(option A) must be installed on the 484A KTUs
involved and the single spurt audible ringback
option (option C) installed on the 486A KTU (service
circuit). If HFAI is removed from a station, the
484A KTU should be changed back to the interrupted
ring option (option B).
Note:
If any station in the system has
HF AI, all stations will have single spurt audible
alerting tone since option C is on a system
basis. In addition, the station associated on
the station circuit KTU with the HFAI station
will have continuous ring. For example, if
station 20 has HF AI, station 21 will have
continuous alerting tone.
The 2A transmitter-receiver is connected to the
station as shown in Fig. 6. Additional information
on the 2A transmitter-receiver can be found in
Section 518-010-115.
5.04
Stations with HF AI operate as follows:
(1) When an HFAI station is dialed, the microphone
in the adjunct is turned on as indicated by
