Connectible Terminals

The OpenCom 100 ports already offer a large number of possibilities for con-
necting terminals. By installing additional interface cards (in an OpenCom 130 /
150) the number of ports can be increased as required.
One of the many possible configurations is shown in the following diagram.

Example of port assignment of the OpenCom 130 with terminals

3.12.1 Internal/External S

All S ports can be operated externally, i.e. on an ISDN network termination unit.
0
The S 2 port of an OpenCom 130 and an OpenCom 131 can also be connected
0
internally. S ports on interface cards (available for an OpenCom 130 and
0
OpenCom 150) can also be switched external/internal. It is not possible to use
both assignments simultaneously.
Up to eight devices per bus (ISDN telephones, ISDN fax machines, ISDN base sta-
tions, ISDN cordless telephones, ISDN adapters for the PC among others) can be
connected to the internal S
these devices can be supplied by the bus; if more devices are used, they then
require their own power supplies. The internal S
point calls as per the DSS1 protocol (Euro-ISDN).
