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.
