A jack includes a body having a plurality of electrically conductive spring contacts and a first and second plurality of connection locations, and a plurality of conductive pins secured to the body and projecting from walls of the body. A circuit board is secured to the body and provides circuit paths to make electrical contact between the spring contacts and the connection locations. The jack is usable in a chassis to form a jack and chassis assembly, wherein the chassis has an open front face and an open back face. The open back face permits accessibility to the projecting pins of the jack, such that it may be wire connected. Secured to the chassis is a circuit board having a plurality of sockets. The sockets provide power and ground connections to each jack. Methods of assembling and providing DSX connections include structures as described herein.
