Abstract
Abstract Disclosed is a network interface unit which includes customer bridges and an array of circuits such as maintenance termination units (MTUs). The MTUs are provided on printed circuit boards, each including a male and female connector. Each board is inserted in between posts in the unit housing so that the female connectors plug into a mother board at the bottom. Jack wires are plugged into the male connectors and extend to the customer bridge portion of the unit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
118 words
Apparatus for connection to a telecommunications network comprising: a housing; a printed circuit mother board mounted within the housing and adapted for connection to the telecommunications network; an array of printed circuit boards mounted essentially perpendicular to said mother board, each circuit board including first and second electrical connectors; a third electrical connector coupled to the second connector on the board, said third connector including a wire pair extending therefrom and coupled to one of an array of jacks mounted in the housing; and a fourth connector on the mother board to which the first connector is coupled, the third and fourth connectors being capable of electrically coupling together when the circuit board is removed from the housing.
Claim 2
Dependent Claim
