aLTE / 4G antennas
Connect the two supplied cellular
antennas to the connectors located
at the device‘s sides.
bVDSL / ADSL interface*
Use the supplied DSL cable for the
IP-based line to connect the VDSL
interface and the provider’s telephone
socket. For more information, please
contact your Internet service provider.
*For operation with over POTS devices
please use the DSL cable with the dark
blue plugs.
cEthernet interfaces
Use the cable with the kiwi-colored
connectors to connect one of the
interfaces ETH 1 to ETH 4 to your PC,
an IP telephone or a LAN switch.
dAnalog interfaces
Connect analog terminal devices to
the analog interfaces either directly
via RJ11 or with the help of the
enclosed TAE adapter.
eSerial interface
Conguring the device via the serial interface
requires a serial conguration cable
(available as an accessory).
fISDN interfaces
ISDN 1: Internal (NT) or external (TE) ISDN bus.
This feature is controlled by LCOS.
ISDN 2: Internal (NT) ISDN bus.
A 100-Ohm resistor for line termination is
switchable in LCOS.
gPower
When connecting the cable to the device, turn
the bayonet connector 90° clockwise until it
clicks into place.
Use only the supplied power adapter.
hSIM card slot (bottom side of the device)
Release the SIM-card holder and lever it
upwards. Slide the SIM card into the guide slot
of the SIM-card holder. Press the holder down
