A LAN line (twisted-pair line in accordance with 10BaseT or 100BaseTX) can be up
to 100 m long. Secure operation with 100 Mbit/s requires the use of category 5
lines and line sockets. Use a shielded Ethernet cable (STP cable, Shielded Twisted
Pair cable).
3.10.6 DSL Port
External DSL modems can be connected via the LAN port. In the case of the
OpenCom 100, the output of the DSL modem (NTBBA) is led to the LAN port of the
OpenCom 100 via an external switch or hub. The router subsequently converts the
PPPoE protocol to the TCP/IP protocol of the LAN.
Connecting the OpenCom 100 to the network via ISDN and DSL
Connection of the DSL modem is via a crossover twisted-pair line. You can also use
a switchable port on the hub, which is usually indicated by an “X”.
Note:
If an expansion module is installed in an
OpenCom 130
, you can also use the unused LAN2 port to
activate the DSL modem. Due to the “auto-crossover” func-
tion, you do not require a cross-wired line with a LAN port of
the expansion module. If you are operating this
OpenCom 130 as a slave system in a cascaded PBX, the LAN0
port on the expansion module of the slave system can be
used instead (see
PBX Cascading
starting on page 122).
