LAN Port

The LAN port (OpenCom 120: LAN 1
port) enables the integration of the
OpenCom 100 in an existing in-
house LAN by means of a 10-Mbit
hub.
The LAN cable must not exceed
100 m in length.
The second LAN port of the
OpenCom 120 is intended only for
networking two OpenCom 120/120
or 110/120 systems.

Hub
With the OpenCom 100, the output
of the DSL modem (NTBBA) is led to
the LAN port of the OpenCom 100
(LAN 1 in the case of the OpenCom
120) via a switch or hub. The router
subsequently converts the PPPoE
protocol to the TCP/IP protocol of
the LAN.
The connection of the DSL modem
is via a crossover twisted pair cable.
If so desired, you can also use a
switchable port on the hub, which is
usually indicated by an "X."

PCM Port

The PCM port is used to connect two
OpenCom 120 systems, or an Open-
Com 110 with an OpenCom 120
system by means of a special trans-
mission method called Pulse Code
Modulation. The RJ-45 cable used
must not exceed 4 m in length.

Sync Port

Net
The twin-wire Sync port is used
when the OpenCom 100 functions
as a sub-system for a main system,
which is a DECT system.
