PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE
When set high, the ICONCAT bit configures the incoming section of the TUPP
to operate in AU4 mode. When the ICONCAT bit is set low, the incoming
section operates in AU3 mode (or equivalently, STS-1 mode).
When set high, the ITMFEN bit enables the TUPP to use the ITMF input
signal to locate tributary multiframe boundaries. The H4 bytes in the incoming
data stream are ignored. When ITMFEN is set low, the H4 bytes are used to
locate the boundaries, and the ITMF signal is ignored.
The ITMFH4 bit selects the location of the ITMF in the tributary multiframe.
When ITMFH4 is set high, ITMF is pulsed high to mark the H4 byte which
indicates that the next AU3/4 or STS-1 frame is the first frame of the tributary
multiframe. When ITMFH4 is set low, ITMF marks the V1 byte of the first
tributary. ITMFH4 is ignored if ITMF is disabled by setting the ITMFEN bit low.
The IOP bit controls the expected parity on the incoming parity signal IPAR.
When IOP is set high, the parity of the parity signal set, together with IPAR is
