During a power failure, the carbon agent headset on the M2216ACD-2 will
fail and the electret supervisor's jack can be used as an agent jack. If no
headset was plugged in to the electret jack at this time, the call is dropped, the
agent logged off and must log in again once the electret headset is plugged in.
When power is restored, the carbon jack returns automatically.
Power Supply Board
The power supply option consists of a Power Supply Board which mounts
inside the telephone, coupled with an external wall-mount transformer or
closet power supply which provides power to the Power Supply Board. The
Power Supply Board receives its power through pins 1 and 6 of the line cord.
The Power Supply Board connects to the telephone through a 14 pin bottom
entry connector.
The Power Supply Board comes factory installed with any configuration of
the M2016S and M2216ACD-2. The M2006 and M2008 require the Power
Supply Board with the addition of any option. The M2616 requires the Power
Supply Board with any option except the Display Module.
