If there is a danger of lightning strikes,

Note
Once the station line connected between a station and
the exchange is short-circuited or a ground fault occurs
on the cable, power cannot be supplied to the station
even when the short or ground fault is removed.
To restore the situation, be sure to disconnect the cable
connector at the station or exchange, and then connect it
again after several seconds.
