Module installation
The modules have already been taken into account for the PABX system. If a module is installed prior to initial commissioning, the numbers
are automatically assigned to the connections.
Various modules can be used for the PABX systems. You should first make a backup copy of all pabx data and then reset the system to default
state (code »999«). Switch the system off, then mount the modules. Restart the system.
Disconnect the PABX from all analog, door terminal and ISDN connections. Attention! You may be electrostatically
charged. To ensure that you have no electrostatic charge, touch a conducting object connected to»ground« (e. g. wa-
ter pipe) before you open the PABX system.
Please observe that only one module can be inserted into each available PABX slot:
Slot 2 = Module elmeg M 1 POTS or module elmeg M 2 a/b.
Slot 1 = Module elmeg M 4 DSP (only elmeg T444).
