Abstract
A line switching apparatus for switching from a telecommunication line to a backup line in the event of occurrence of a fault on the telecommunication line includes a memory storing time zone information for monitoring the state of the telecommunication line, so that, when occurrence of a fault is detected during this monitoring time zone, the line switching apparatus switches from the faulty telecommunication line to a backup line, while when the time is outside the monitoring time zone, the state of the telecommunication line is not monitored so as to prevent unnecessary switching from the telecommunication line to the backup line.
