This chapter explains how to connect the LANCOM Business-VoIP-Router to
the telephone network and how to connect terminal equipment to the
LANCOM Business-VoIP-Router.
The connections described relate to the operation of the LANCOM Business-
VoIP-Router as a "stand-alone" PBX. The devices can be connected in
different manners, and information about these options can be found in the
appropriate user manual and/or in the LCOS reference manual.
LANCOM Business-VoIP-Routers feature an ISDN interface and a number of
LAN connectors, making them suitable for a simple SIP telephone
infrastructure.

LANCOM 1723 VoIP and LANCOM 1823 VoIP

The VoIP routers LANCOM 1723 VoIP and LANCOM 1823 VoIP feature two
ISDN interfaces, two LAN interfaces, two connectors for analog terminal
devices and the option to connect an analog line to the exchange. This range
of options is capable of supporting a sophisticated telephony infrastructure.
To operate in this mode, the DIP switches on the underside of the

LANCOM 1723 VoIP and LANCOM 1823 VoIP devices must be in the
following positions: DIP switches 1 to 8 in the up position, DIP
switches 9 and 10 down. This is the ex-factory setting. Check the
position of the DIP switches and set them correctly if necessary.
Before altering the DIP switch settings, remove all cables from their
sockets and switch the device off.
Remove the see-through cover over the DIP switch.
We suggest that you use a screwdriver to set the DIP switch to the
desired position.
Replace the see-through cover and reconnect the cables as described
for your model in the user manual and as described in the following
sections.
