Putting the telephone into operation

Note that the NTBA must be connected to the power grid.

The Profiset 30isdn takes the necessary power from this

NTBA.

In order to avoid unauthorized unplugging of the telephone connecting cord from the telephone socket, the plug is protected. Use a small screwdriver or the like to unplug the connector.

Step 3: Entitle the device to operate in restricted powering conditions

The restricted powering switch is located on the under- side of the device. The recessed sliding switch can be moved with a screwdriver.

If the switch points to the symbol A , your telephone is entitled to operate in restricted powering conditions that means that the important telephone functions can still be used.

If you connect more than one unit to your ISDN connection, only one unit can be operated during restricted powering. Mark this unit accordingly!

Step 4: Program the multiple subscriber numbers (MSNs)

We recommend that you enter the MSNs when first putting the telephone into operation, because only then you can use all the functions of your telephone. The MSNs (Multiple Subscriber Numbers) are the call numbers you were assigned for your ISDN connection.

These numbers are entered as follows:
