    摘要: The invention provides a network protector (10) which comprises node connecting means (14) for connecting the network protector to a node (24) in an electronic network and hub connecting means (16) for connecting the network protector to a hub (22) in the electronic network. The network protector also includes a non-earthed surge protection circuit (28) for allowing electronic communication between the node connecting means and the hub connecting means. The surge protection circuit includes circuit breaking means (40, 42, 48, 50) for disrupting electronic communication between the node connecting means and the hub connecting means in response to electrical surges exceeding a specified value.

    摘要: The present invention provides a telecommunications system indicator and protector (10) for indicating the working status of a telecommunications line (16) and of equipment (12, 14) which can be connected to the telecommunications line. The telecommunications system indicator includes connecting means whereby the telecommunications system indicator can be connected to the telecommunications line and the equipment respectively, a line testing circuit (Block B) and an equipment testing circuit (Block A). The telecommunications system indicator further also includes a switch (18) which is movable between a first position wherein the telecommunications line is connected to the line testing circuit and a second position wherein the telecommunications line is connected to the equipment testing circuit as well as an indicator for indicating whether the telecommunications line is in working order when the switch is located in the first position, and whether the equipment is in working order when the switch is located in the second position.
