display on the system telephone connected to the slave system.

Notes

Observe the following when operating a cascaded PBX system:

z All U

, S

and a/b ports of the slave system can be used with

appropriate telephones. All features of system telephones on

ports are available without restriction.

z The S

ports of the slave system can also be used for trunk

lines or for PBX networking (see PBX Networking starting on

page 77).

z It is not possible to operate a DECT base station on one of the

ports of the slave system.

z The COM, actor/sensor and –if present– LAN2 ports of the

slave system cannot be used.

z 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.

z The slave system cannot be addressed directly through a LAN.

For configuration, always use the Web console of the master

system.

z A memory card installed in the slave system (Forum Voice)

cannot be used.
