PSS -INTERFACES
General
The passenger service system (PSS) uses an ARINC 629 interface and an in-flight entertainment (IFE) system ARINC 628 head-end interface to get data from other systems. An intersystem (I/S) bus connects the three cabin zones. Other buses connect the other PSS components.
The passenger interface for PSS is through an IFE system ARINC 628 zone interface.
The diagram shows zone 1 interfaces. The other zones are the same.
ARINC 629
The passenger address/cabin interphone (PA/CI) controller connects to the left systems ARINC 629 bus. The cabin system management unit (CSMU) connects to the right systems ARINC 629 bus. The PA/CI and CSMU get data from these systems to control the passenger information signs:
