1. A terminal adapted to be connected to a local area network which is adapted to provide a remote supply of power to said terminal in the event of a failure of a local supply of power to said terminal, said terminal comprising:
- a local power supply unit (S3) which provides said local supply of power to said terminal;
a coupler (D1) for coupling said terminal to said local area network; and
a detector (RDSD;
RPSD′
) for detecting whether or not said terminal is receiving any remote supply of power provided by said network, wherein said terminal is rebooted if said detector detects that said terminal is no longer receiving any remote supply of power provided by said network, and wherein said local supply of power provided by said local power supply unit is interrupted to reboot said terminal if said detector detects that said terminal is no longer receiving any remote supply of power provided by said network.
