Supporting synchronization status messages on building integrated timing supply synchronization supply unit remote shelves

Abstract

Systems and methods are described for supporting synchronization status messages (SSM) on building integrated timing system synchronization supply unit (BITS-SSU) remote shelves. A method includes providing a composite clock reference to a remote synchronization supply unit from a master synchronization supply unit; providing a synchronization status message to the remote synchronization supply unit; relaying the composite clock reference from the remote synchronization supply unit; and relaying the synchronization status message from the remote synchronization supply unit. An apparatus includes: a master synchronization supply unit; and a remote synchronization supply unit coupled to the master synchronization supply unit, the remote synchronization supply unit including a composite clock reference input to receive a composite clock reference from the master synchronization supply unit, a composite clock output to relay the composite clock reference, a synchronization status message input to receive a synchronization status message, and a synchronization status message output to relay the synchronization status message.
