Interfaces and Connectible Terminals PCM Port
PCM Port
The PCM port on the MC+1-3 central
control module is used to cascade
two PBXs.
Cascaded PBXs must be connected
by means of a twisted-pair cable
with RJ45 plugs. This cable transmits
voice data as well as administration
data between the PBXs.
All eight pins of the cable must be
wired 1:1. Connect the cable to the
PCM port of the MC+1-3 central con-
trol module of each of the two PBXs.
The shielded CAT-5 cable must not
be longer than 50 centimetres.
For further information, refer to PBX
Cascading starting on page 98.
LAN Port
The LAN port (Ethernet interface) on
the MC+1-3 central control module
allows the integration of the
OpenCom 510 into a company LAN
(Local Area Network) with the use of
a 10-Mbit hub or switch. In such a
configuration, the OpenCom 510
can, for example, act as an IP router
for establishing Internet connec-
tions.
The Ethernet interface supports
transmission rates of 10 Mbits/s and
100 Mbits/s in half duplex or full du-
plex mode. The transmission rate
and mode are selected automatically
(Auto Sensing function).
A LAN cable (twisted-pair in accord-
ance with 10BaseT or 100BaseTX)
must not be longer than 100 m. Safe
operation with 100 Mbits/s requires
the use of category 5 cables and
sockets. Use a shielded Ethernet
cable (STP cable, Shielded Twisted
Pair cable).
DSL
External DSL modems can be con-
nected via the LAN port. This re-
quires the use of an external switch
or hub which connects the output of
the DSL modem (NTBBA) to the LAN
port of the OpenCom 510. The router
will then convert the PPPoE protocol
to the TCP/IP protocol of the LAN.
The DSL modem is connected by
means of a crossed twisted-pair ca-
ble. Alternatively, you can use a
switchable port on the hub, which is
usually marked with an “X”.
