1. A communication system assembled on an aircraft, the system comprising:
- an intrabus detachably coupled mounted within the aircraft, the intrabus comprising communication lines and power lines;
at least one intrabus interface panel that provides access to the intrabus;
a plurality of line replaceable equipment racks (LRERs), each LRER being preassembled prior to being loaded onto the aircraft and comprising electronic equipment affixed within the LRER and at least one rack interface panel that provides access to the electronic equipment; and
a plurality of cables that couple the at least one rack interface panel of each LRER to the at least one bus interface panel;
wherein the intrabus comprises a first intrabus having a first level of security and a first intrabus interface panel, and a second intrabus having a second level of security and a second intrabus interface panel, wherein a security level of each LRER of the plurality of LRERs is assigned based on a coupling of the rack interface panel of a given LRER of the plurality of LRERs to one of the first intrabus interface panel and the second intrabus interface panel, wherein the first and second security levels are different security levels.
