Note: Changes to the configuration while initialising the
slave system may trigger error reports referring to the ongo-
ing initialisation.
You can see that the initialisation has been completed from the display on the
system telephone connected to the slave system.
11.3.1 Notes
Observe the following when operating a cascaded PBX system:
■ All U
pn
, S
0
and a/b ports of the slave system can be used with appropriate tele-
phones. All features of system telephones on U
pn
ports are available without
restriction.
■ The S
0
ports of the slave system can also be used for trunk lines or for PBX net-
working (see PBX Networking starting on page 153).
■ It is not possible to operate a DECT base station on one of the U
pn
ports of the
slave system.
■ The COM, actor/sensor and LAN ports of the slave system cannot be used. The
LAN ports on the add-on module of slave system can be used without
restriction.
■ The two communications systems must have a direct Ethernet connection or
be connected via a hub in order to exchange data. They cannot be connected
through a router.
■ The OpenCom 150 is equipped with the PCM2 port in order to realize cas-
cading of a third PBX with a future release. Use one of the two LAN0 ports, to
connect the OpenCom 150 to the Local Area Network.
■ The slave system cannot be addressed directly through a LAN. For configu-
ration, always use the Web console of the master system.
■ A memory card installed in the slave system (OpenVoice, OpenAttendant)
cannot be used.
■ To operate the slave system again normally, you must reset it to its factory set-
tings (refer to
Resetting the System Data starting on page 87).
