A selectable compatibility jack has at least a partially hollow housing member or jack frame and a plurality of spring contact members or leads extending from the rear portion thereof to the connector end. The housing has a front face with an opening therein configured to receive a plug. A circuit member, such as a printed wiring board is mounted and affixed within the housing and has circuit components on a surface thereof. Actuator means responds to the insertion of a low performance plug into the jack to cause the leads to contact certain ones of the circuit elements, such as capacitance pads, to alter the crosstalk and transmission loss characteristics of the jack. Clearance means within the jack prevent the actuator means from being actuated when a high performance plug is inserted in the jack.
