Instruction manual

Features
An outside caller on hold hears Music-on-Hold, if programmed, or silence.
If a call on hold is not picked up within a set length of time, the person who put
the call on hold hears a reminder —
a beep if the person is a telephone user, or
an abbreviated ring if the person is a Direct-Line Console (DLC) or QCC system
operator. This Hold Timer is fixed at 60 seconds for telephone users. It is
programmable for DLC and QCC operators, as described below.
At an MLX display telephone, the message Call On Hold appears briefly on
the display when the user first puts a call on hold. This message reappears
briefly each time the Hold Timer expires.
Five system-wide Hold options can be set through system programming:
■ Hold Disconnect Interval determines how long the system waits before
releasing the trunk when an outside caller on hold on a loop-start trunk
hangs up, This interval can be set to the following values:
— Long (the factory-set default) — 450 ms
— Short — 50 ms
The Hold Disconnect Interval should be programmed to match the local
telephone company’s disconnect timing: long if disconnect is unreliable,
short if disconnect is reliable.
The Hold Disconnect Interval applies to all telephone users and system
operators.
■ DLC Operator Automatic Hold determines what happens when a DLC
operator is on a call and presses another line button, an Auto Dial
button, or a Direct Station Selector (DSS) button. This option can be set
to the following values:
— Enabled — the active call is automatically put on hold. This
prevents accidental disconnection of callers.
— Disabled (the factory-set default) — the active call is
disconnected. This allows the operator to disconnect one call
and answer or dial another by pressing a single button.
The DLC Operator Automatic Hold setting applies only to DLC operators.
■ Operator Hold Timer determines how long a call stays on hold before
the system reminds the DLC or QCC operator that it has not been picked
up. The operator hears a reminder (abbreviated ring) when the timer
expires. This timer can be set to a value of 10 to 255 seconds (the
factory-set default is 60 seconds).
If a call is ringing at the console when the timer expires, the reminder is
delayed for 10 seconds so that the operator will have a chance to hear it.
(If after 10 seconds the call is still ringing or a new call is ringing, the
reminder is delayed for another 10 seconds, and so on.)
The Operator Hold Timer applies only to DLC and QCC operators.
