The following functions are performed:
• Synchronization on pulse frame and multiframe
• Error indication when synchronization is lost. In this case, AIS is automatically sent to
• Initiating and controlling of resynchronization after reaching the asynchronous state.
• Detection of remote alarm indication from the incoming data stream.
• Separation of service bits and data link bits. This information is stored in status
• Generation of various maskable interrupt statuses of the receiver functions.
