Figure 46 Receive Line Data Link Clock and Data Extraction
The Receive Section Data Link Clock and Data Extraction Timing diagram (Figure 47) shows
the relationship between a RDCC serial data output and its associated RDCLK when configured
for section DCC. In this mode, RDCLK is a 216 kHz, 50% duty cycle clock that is gapped to
produce a 192 kHz nominal rate. RDCC is updated on the falling edge of RDCLK. The D1-D3
bytes shifted out of the S/UNI-8x155 in the frame shown are extracted from the corresponding
transport overhead channels in the previous frame.
