An aircraft cabin management system including a) a communication interface system; b) a seat interface system; c) at least one Cabin Distribution Unit (CDU); and, d) a communication network. The communication interface system includes an integrated Cabin Server Unit (CSU) providing the combined functionality of aircraft communications, networking, and computational resources; and, an Information Maintenance Portal (IMP) providing maintenance access for the users of the aircraft cabin management system and the users of avionics equipment. The seat interface system includes a number of Modular Seat Interface Units (MSIUs), each MSIU providing device input/output connections for a defined portion of the interior of the aircraft cabin. The communication network operatively interconnects the communication interface system; the seat interface system; and the at least one CDU, as well as other equipment installed in the aircraft. The aircraft cabin management system provides an integrated communications and service backbone.
