The Hold key status light indicates whether your Optiset terminal's
own call leg is on hold and selected.
This is achieved by the
switching system returning a Hold Acknowledge to the terminal for
the selected call.
When you want to retrieve a held call, press the line call associated
with the held call, or select the Retrieve menu option. This will
cause your Optiset terminal to send a retrieve request to the
central-office switching system. When the Retrieve Acknowledge
message is returned to your terminal by the swilching system, the
Hold status light will turn off, indicating that the call is no longer on
hold.
If
your Optiset terminal is in Preview mode rather than Line Hold
mode, you can select and review all held calls using the line keys.
After previewing a held call. press the Connect or Hold key, go off­
hook. or select the Retrieve menu option to send a retrieve request
to the central-office switching system. The selected held call will be
retrieved after the Retrieve Acknowledge message has been sent
to your terminal by the switching system. The Hold status light will
be turned off to indicate that the call is no longer on hold. All other
held calls will remain on hold.
If
the switching system should reject your retrieve request. the call
will remain on hold. You may attempt to retrieve the call later.
Intercom
Intercom is a combined local/switch-based feature that is operates
only on an Optiset terminal used as a CACH EKTS phone. The
feature requires an Intercom feature key to have been programmed
on your terminal.
The Intercom key will operate in one of two ways. If it has been
programmed with an intercom number associated with another
terminal in the intercom group, you can press the Intercom key to
automatically ring that terminal.
If
the Intercom key has not been
programmed with an intercom number, you will receive dial tone
when you press it. You can then dial the intercom number (up to 2
digits) of the terminal you want to call.

The status light associated with the Intercom key will alert you to
incoming intercom calls and will indicate the status of intercom
calls.
Line Status/Speed Dial
If
your Optiset terminal operates as a CACH EKTS phone. the
Speed Dial feature keys can be programmed so that the associated
status lights represent some other function. One example of this is
the Line Status/Speed Dial key, which functions as a normal Speed
Dial key when you press it, while the associated status light
represents activity on a programmed call appearance.
When you press the Line Status/Speed Dial key. the Optiset
terminal places a call on an idle prime line appearance. However,
unlike a normal Speed Dial key, pressing this key will not turn on
the associated status light.
The status light associated with the Line Status/Speed Dial key
lights whenever there is any activity on the line CACH 10 or
ON.
However, the only cadence is steady on, regardless of the activity
(dialing, ringing, connnected, or held) on the line.
Make Busy
Make Busy Is a switch-based feature that prevents incoming calls
from being presented to your Optiset terminal. If your terminal has
been subscribed to this feature, the Make bUSy? menu option will
be available through the idle menu display. Simply press the tI'
dialog key to activate the feature. Thereafter, the idle menu display
will present the Cancel make busy? option. Press the tI' dialog key
with this option displayed to cancel the Make Busy feature.
Mute
Mute is a local feature that blocks the outgoing speech circuits in
the Optiset terminal.
In the speaker mode, Mute blocks the
microphone; In the handset or headset mode, Mute blocks the
mouthpiece. The feature is activated by pressing the Mute feature
key. When Mute is active, the status light next to the Mute key is
lighted.
