OPTION UNIT
It is possible to install an option unit in the phone. The option unit, which is built into the
foot console, provides the phone with a gigabit Ethernet interface and an extra bell and
busy signal.
Gigabit Ethernet
The option unit offers a gigabit Ethernet interface module, the purpose of which
is to pass on gigabit traffic to the PC connected to the IP terminal. The phone
itself does not require the gigabit speed.
Extra bell and busy signal
The option unit offers an interface for auxiliary equipment, such as an external
bell or a busy signal indicator. There are three alternatives using this function:
•
Busy Signal. The busy signal is activated in off-hook mode. Can be used
to control a Do-not-disturb lamp at the door.
•
Extra Bell. The extra bell is activated parallel to the ring signal.
•
Combined Bell/Busy. A combined busy signal and extra bell. Steady
active in off-hook mode, and flashing when the phone rings. Can be used
for lamp indication in an office landscape, for example.
INSTALLING AN OPTION UNIT
To install the option unit, do the following:
1.
Log off the phone and disconnect the power from the phone to avoid electrostatic
discharges, ESD.
2.
Connect the ribbon cable to the phone, making sure the cable does not get stuck.
3.
Attach the option unit at the arrows on the back of the phone. Press until you hear
a click sound.
Dial the number you want to call. When
someone answers, you need to pick up
the handset for the called person to be
able to hear you.
Replace the handset.
