PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE
When set high, the OCONCAT bit configures the outgoing section of the
TUPP to operate in AU4 mode. When the OCONCAT bit is set low, the
outgoing section operates in AU3 mode (or equivalently, STS-1 mode).
When set high, the OJ1EN bit enables the TUPP 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, DOUT[7:0]. The OSPE 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).
When the OJ1EN bit is low, the TUPP output bus operates in locked mode
where the OC1J1 signal marks the first C1 byte only in the outgoing data
stream, DOUT[7:0]. In this mode, the OSPE input must be logic zero for the
C1 byte. The TUPP defaults to fixed output timing where the J1 bytes of the
STS-1, AU3 or AU4 synchronous payload envelopes are assumed to
immediately follow the C1 bytes.
