SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
These registers report the number of remote error indications (REI) detected in
TU #3 in TUG2 #1 to TUG2 #7 in the previous accumulation interval. These
registers contain invaild data in TU3 mode. When the corresponding TUG2
tributary group is configured to TU2 (VT6) or VT3 mode, the associated registers
in this set contain invalid data.
REI[10:0]:
The REI[10:0] bits report the number of tributary path remote error indications
that have been detected since the last time the REI registers were polled. The
REI registers are polled by writing to the Input Signal Activity Monitor,
Accumulate Trigger register. The write access transfers the internally
accumulated error count to the REI registers within 10 µs and resets the
internal counter simultaneously to begin a new cycle of error accumulation.
