The Receive Unipolar J2 Stream diagram (Figure 36) shows the unipolar J2 receive signal on the
RDATI input. LCV indications, detected by an upstream B8ZS decoder, are indicated on input
RLCV. RLCV is sampled each bit period. The PMON LCV Event Counter is incremented each
time a logic one is sampled on RLCV.

The generic receive stream diagram (Figure 37) illustrates how ROHM is used to mark the
location of the transmission system overhead bits in the RDATI stream. RDATI and ROHM are
both sampled on the rising edge of RCLK.
