FUNCTIONAL TIMING  
13.1 DS3 Line Side Interface Timing  
All functional timing diagrams assume that polarity control is not being applied to  
input and output data and clock lines (i.e. polarity control bits in the TEMAP  
registers are set to their default states).

RPOS

RNEG  
The Receive Bipolar DS3 Stream diagram (Figure 37) shows the operation of the  
TEMAP while processing a B3ZS encoded DS3 stream on inputs RPOS and  
RNEG. It is assumed that the first bipolar violation (on RNEG) illustrated  
corresponds to a valid B3ZS signature. A line code violation is declared upon  
detection of three consecutive zeros in the incoming stream, or upon detection of  
a bipolar violation which is not part of a valid B3ZS signature.

The Receive Unipolar DS3 Stream diagram (Figure 38) shows the complete DS3  
receive signal on the RDAT input. Line code violation indications, detected by an  
upstream B3ZS 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.
