the MIKE-ON LED, and a single 1/2-second tone
burst is heard at both stations.
(2) After hearing the tone burst, the calling
party can voice-signal the HF AI station.
The HFAI station may answer without going
off-hook via the mike in the adjunct.
(3) If the HF AI station does not want local
conversation or noise to be heard, the
MIC-OFF button must be depressed, during
which time the LED will turn off.

return to HF AI by releasing the MIC-OFF button.
The following conditions apply to HFAI calls:
5.05
(a) If an HFAI station is called on a dial
conference call, it must go off-hook within
16 seconds of the first called station going off-hook
to prevent the possibility of a conference call
being broadcast at an unattended HF AI station.
After 16 seconds the alerting tone will time out
but the lamp at the HFAI station will continue
to flash. The HF AI station can enter the
conference while the lamp is flashing but only
using the handset.
(b) A station in HFAI cannot be ·added as the
third party in call add-on. The station can
be called and can converse while in HFAI but
to be added on, must go to handset operation
before the calling station operates the switchhook
a second time to return to the original connection.
Failure to go to handset will cause the HF AI
station to be dropped.
(c) Calls cannot be transferred to a station in
the HFAI mode without going off-hook before
the transfer.
will be dropped.
(d) HFAI stations can be placed on station hold
but not consultation hold. This prevents an
HF AI station being connected to a CO/PBX line
for transmission reasons.
(e) Two HFAI stations called on a dial conference
call will not be able to communicate with
each other and must go to their handsets.
(f) Calls cannot be orignated in HF AI.
