SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
interrupt is generated when the accepted path signal label changes. Interrupts
due to change of PSL are masked when COPSLE is set low.
PSLME:
The PSLME bit enables the tributary path signal label mismatch interrupt for
tributary TU #4 in the corresponding TUG2. When PSLME is set high, an
interrupt is generated when the accepted path signal label changes from
mismatching the provisioned PSL to matching the provisioned value, or vice
versa. Interrupts due to PSL mismatch status change are masked when
PSLME is set low.
PSLUE:
The PSLUE bit enables the tributary path signal label unstable interrupt for
tributary TU #4 in the corresponding TUG2. When PSLUE is set high, an
interrupt is generated when the received path signal label becomes unstable
or returns to stable. Interrupts due to PSL unstable status change are masked
when PSLUE is set low.
BLKBIP:
The BLKBIP bit controls the accumulation of tributary BIP-2 errors for the
tributary TU #4 in the corresponding TUG2. When BLKBIP is set high, BIP-2
errors are counted on a block basis; the BIP error count is incremented by
one when one or both of the BIP-2 bits are in error. When BLKBIP is set low,
the BIP error count is incremented once for each BIP-2 bit that is in error.
CONFIG[1:0]:
The CONFIG[1:0] bits specify the tributary configuration of the corresponding
TUG2. The configuration specified by the CONFIG[1:0] bits are selected as
follows:
