maintenance
Modem connection
Your supplier can perform remote maintenance on the cordless system by a
modem connection.
The modem can be connected to the radio exchange with the Modem shell
adapter (RNTNB 102 109) and the PC (RS232) cable. The Modem shell
adapter connects with a 9 pins connector to the RS232 cable. At the other side
it has a 25 pins connector, to which a modem can be connected (see figure 6).

With CSM you can initialise the modem on the side of the cordless system for
remote maintenance of the cordless system.

In case of troubles with the modem, see the accompanying documentation.
