The outgoing tributary V5 byte (OTV5) signal
marks the various tributary V5 bytes.
In outgoing byte interface mode (OBMODE set
high), OTV5 is set high to mark each tributary
V5 byte on the OD[7:0] bus. When the outgoing
tributary is a TU3, OTV5 marks the J1 byte of
the TU3. In floating mode, OTV5 contains valid
data only for bytes in the VC3 or VC4 virtual
container(s), or the STS-1 synchronous payload
envelopes. Its contents should be ignored for
bytes in the transport overhead. In locked
mode, OTV5 is set low for transport overhead
bytes. OTV5 is updated on the rising edge of
SCLK.
In outgoing nibble interface mode (OBMODE set
low), OTV5 is set high to mark each tributary V5
byte on the OD[3:0] bus. When the outgoing
tributary is a TU3, OTV5 marks the J1 byte of
the TU3. In floating mode, OTV5 contains valid
data only for bytes in the VC3 or VC4 virtual
container(s), or the STS-1 synchronous payload
envelopes. Its contents should be ignored for
bytes in the transport overhead. In locked
mode, OTV5 is set low for transport overhead
bytes. OTV5 is updated on the rising edge of
NSCLK.
