A jack assembly is disclosed including a mount having a plurality of electrical contact members disposed in a predetermined array and a plurality of jacks. The jacks are releasably attachable to the mount. Each of the jacks includes a jack body formed of dielectric material. The body has an interior with a plurality of bores extending through the body in communication with the interior. The bores are sized to receive tip-and-ring plugs of known dimensions. A plurality of electrically conductive spring contacts are disposed within the chambers with first ends thereof presenting electrical contact points disposed in a predetermined array. A circuit board is attached to the body and has circuitry which includes a first and second plurality of circuit contact points. The first plurality of circuit contact points is disposed on the circuit hoard to make electrical contact with the electrical contact points of the spring contacts when the circuit hoard is connected to the body. The second plurality of circuit contact points are disposed to make electrical contact with the plurality of exposed electrical contact members of the mount when the jack is attached to the mount.
