Connection of Handset /Headset
It is possible to connect a handset or headset to the terminals “EP+, EP–, EM+, EM–” (see connection
diagram
page 29
).
The way the audio output (internal loudspeaker and/or loudspeaker handset/headset) and the audio
feed-in (internal microphone or microphone handset/headset) is carried out at the SIP station, is
defined by means of configuration via the web interface
see page 46

Connection Direct Dialling Buttons
Attention:
For connection of the power supply, the notes and technical data on
page 6
have to be observed!
Note:
If both power supply types (i.e. PoE and supply via “PWR1,PWR2”) are active at the same time, then the
following has to be considered:
In case of a breakdown of the power supply via “PWR1,PWR2”, and the consequentially take over of
PoE, a reboot of the station is initiated.
In case of a breakdown of PoE, and the consequentially switch-over to power supply via
“PWR1,PWR2”, the operation of the station will not be interrupted – provided that the 2nd ethernet
link (“IP downlink” see connection diagram on
page 31
)
is connected to the respective LAN network.
