SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
matched identifier. Interrupts due to TIM status change are masked when
TIME is set low.
TIMV:
The TIMV bit indicates the trail trace identifier mismatch status of tributary
TU #2 in the corresponding TUG2.
LEN16:
The path trace message length bit (LEN16) selects the length of the path
trace message to be 16 bytes or 64 bytes for tributary TU #2 in the
corresponding TUG2. When LEN16 is set high, the message length is set to
16 bytes. When LEN16 is set low, the message length is set to 64 bytes.
NOSYNC:
The path trace message synchronization disable bit (NOSYNC) disables the
synchronized writing of the path trace message into the trace buffer based on
the contents of the message for tributary TU #2 in the corresponding TUG2.
When LEN16 is set high and NOSYNC is set low, the receive path trace
message byte with its most significant bit set to logic one will be written to the
first location in the buffer. When LEN16 is set low, and NOSYNC is also set
low, the byte after the carriage return/linefeed (CR/LF) sequence will be
written to the first location in the buffer. When NOSYNC is set high,
synchronization is disabled, and the path trace message buffer behaves as a
circular buffer.
CONFIG[1:0]:
The CONFIG[1:0] bits specify the tributary configuration of the corresponding
tributary group TUG2. The configuration specified by the CONFIG[1:0] bits
are selected as follows:
