A package for communication equipment has a housing fitted with a locking mechanism and electrical/communication power supply and distribution, and includes UP, DOWN, RIGHT, LEFT faces for assembly with other housings. The locking mechanism includes a rotatable axle penetrating the housing and having a first end located outside of the housing and a second end located inside of the housing. A camming hook having a distal end is mounted on the rotatable axle inside the housing to rotate with the axle and locks into position when rotated in a first direction, to bring a movable electrical contact to make resilient electrical contact with a stationary live contact. When the rotatable axle is rotated in a direction opposite to the first direction, the mechanism becomes unlocked and breaks the electrical connection at the movable electrical contact.
