HDB3 Signature Pattern

The Receive Bipolar E3 Stream diagram (Figure 35) shows the operation of the

TEMAP-84 while processing an HDB3-encoded E3 stream on inputs RPOS[x]

and RNEG[x]. It is assumed that the first bipolar violation (on RNEG[x])

illustrated corresponds to a valid HDB3 signature. A line code violation is

declared upon detection of four consecutive zeros in the incoming stream, or

upon detection of a bipolar violation which is not part of a valid HDB3 signature.

LCV INDICATION

The Receive Unipolar E3 Stream diagram (Figure 36) shows the unipolar E3

receive signal on the RDATI[x] input. Line code violation indications, detected by

an upstream HDB3 decoder, are indicated on input RLCV. RLCV is sampled

each bit period. The PMON Line Code Violation Event Counter is incremented

each time a logic 1 is sampled on RLCV.
