5.1.11
According to the input jitter defined by PUB62411 the FALC56 generates the output jitter,
which is specified in

5.1.12
The following functions are performed:
• Synchronization on pulse frame and multiframe
• Error indication when synchronization is lost. In this case, AIS is sent to the system
• Initiating and controlling of resynchronization after reaching the asynchronous state.
• Detection of remote alarm (yellow alarm) indication from the incoming data stream.
• Separation of service bits and data link bits. This information is stored in special status
• Detection of framed or unframed in-band loop-up/-down code
• Generation of various maskable interrupt statuses of the receiver functions.
• Generation of control signals to synchronize the CRC checker, and the receive elastic
If programmed and applicable to the selected multiframe format, CRC checking of the
incoming data stream is done by generating check bits for a CRC multiframe according
to the CRC6 procedure (refer to ITU-T G.704). These bits are compared with those
check bits that are received during the next CRC multiframe. If there is at least one
mismatch, the CRC error counter (16 bit) is incremented.
5.1.13
The received bit stream is stored in the receive elastic buffer. The memory is organized
as a two-frame elastic buffer with a maximum size of 2
buffer is configured independently for the receive and transmit direction. Programming
of the receive buffer size is done by SIC1.RBS1/0:
