A network communication device is provided, comprising a control processor for controlling operation of the device, a reset module which is controllable independently of the control processor for performing a reset operation of the device, and a reset control interface for receiving a reset signal, the reset module being responsive to the reset signal for performing the reset operation. A monitor is provided for monitoring the status of the control processor and an interface is adapted to transmit information relating to the monitored status from the device. A second, inactive device is provided to protect the communication device in the event of a control fault which renders the communication device unreachable. The protection device includes a reset interface for transmitting a reset signal to the reset module to enable the communication device to release activity.
