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

an external bell or a busy signal indicator. There are three alterna-
tives using this function:

•
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.
