Claim 1
Independent Claim
174 words
A network interface device for terminating network wiring at a subscriber's premises and for connecting the subscriber's wiring to the network wiring, comprising: a set of terminals to which subscriber wiring may be connected; a test jack to which a device known to be operational may be connected; a switch in electrical connection with network wiring, the test jack, and the set of terminals, the switch placing the network wiring in electrical communication with the test jack but not the set of terminals when the switch is in a first position and with the set of terminals but not the test jack when the switch is in a second position; a first door, not covering the set of terminals, which covers the test jack when the first door is closed and which does not cover the test jack when the first door is open; and, activation means for causing the switch to be in its first position when the first door is open and in its second position when the first door is closed.
