OCONCAT
This register configures the TUPP-PLUS functionality that are related to the
outgoing data stream.
OCONCAT:
When set high, the OCONCAT bit configures the outgoing section of the
TUPP-PLUS to operate in AU4 mode. When the OCONCAT bit is set low, the
outgoing section operates in AU3 mode (or equivalently, STS-1 mode).
OJ1EN:
The OJ1EN bit selects the operation of the outgoing data stream to be in
floating or locked mode. When OJ1EN is set high, TUPP-PLUS output bus to
operate in floating mode where the OC1J1 signal marks the first C1 byte and
the J1 bytes in the outgoing data stream, OD[7:0]. The OPL input is used to
distinguish between bytes in the transport overhead and the payload
envelope, and consequently C1 and J1. Only one J1 byte, and one VC or
concatenated SPE, are expected to be marked when configured for AU4
mode (OCONCAT set high). Outputs LC1J1V1 and LPL are held low in
floating mode.
When the OJ1EN bit is low, the TUPP-PLUS output bus operates in locked
mode where the OC1J1 signal marks the first C1 byte only in the outgoing
data stream, OD[7:0]. In this mode, the OPL input must be logic zero for the
C1 byte. The TUPP-PLUS defaults to fixed output timing where the J1 bytes
