Figure 54
LDDATA[7:0]
Figure 55 shows the function of the various telecom DROP bus signals in AU4
mode. Data on LDDATA [7:0] is sampled on the rising edge of LREFCLK. The
bytes forming the VC4 virtual container are identified by the setting the LDPL
signal high. The LDC1J1V1 signal pulses high, while LDPL is set low, to mark
the single C1 byte in every frame of the AU4 transport envelope. The LDC1J1V1
signal is set high again with LDPL high to mark the J1 byte of the VC4. The bytes
forming the various tributary synchronous payload envelopes are identified by
the LDTPL signal being set high. The LDV5 signal pulses high to mark the V5
bytes of each outgoing tributaries.
