Power Failure Installation
Power Failure
In the event of a power failure, all the contents in the memory (program and user data) are saved without
change. The internal clock continues to run for 24 hours. If the power failure lasts longer than 24 hours, the
time and date are reset to the factory setting when power is switched on again. When the first external out-
going call is made, the time and date are set to the current value as given by the exchange. With the
T-Comfort 930 DSL Version 2, date and time generally will be adjusted after the first outgoing connection.
On the multi-terminal access, the T-Comfort 930 DSL Version 1 include an emergency service. In the event of
a power failure, the external S
0
1 port is switched over to the S
0
2 port so that you can still use a connected tel-
ephone to make a call.
Emergency operation on a system access is not possible.
