You can enter any number between 201 and 250.
Ensure that you do not enter the same address as

The default is 250.
(5) Specify the setting for the Inactivity Timeout function.
The Inactivity Timeout function is a modem function
that automatically disconnects telephone lines when
there has been no communication on a connected
line for a set period during error notification.
If power to the MN Converter is turned off due to a
power failure or any other cause while a telephone
line is connected for error notification, the
telephone line remains connected unless this function
is enabled.
This function can be used to release connected lines
in this situation.
The S-register setting used with the Inactivity Timeout function differs depending on the modem model.
Read the modem's instruction manual carefully to ensure that you use the correct setting.

Caution:

If you do not use the Inactivity Timeout function, or if the modem settings are not specified correctly,
Mitsubishi Electric accepts no liability whatsoever for any faults or damage arising from the continued
connection of telephone lines.
Before use, always check that the Inactivity Timeout function is working correctly.
NOTE:
*The Inactivity Timeout function setting differs according to the modem model.
(The S-register number and the units and setting range for inactivity timeout differ.)
Read the modem's instruction manual carefully (AT commands) to ensure that you use the
correct settings.
*If the Maintenance Tool is used to remotely connect to the MN Converter via a telephone line while
the Inactivity Timeout function is being used, the Inactivity Timeout function may disconnect the
telephone line when the Maintenance Tool is not being used.
If you use the Maintenance Tool to remotely connect to the MN Converter via a telephone line, consider
carefully whether to use the Inactivity Timeout function and the length of timeout delay when specifying
the settings.
*When changed this setting, the setting of “Notification contact TEL” is cleared.
