TIP
TIP:
The TIP bit is set to a logic one when the performance meter registers are being loaded.
Writing to the S/UNI-622-MAX Master Reset and Identity register initiates an accumulation
interval transfer and loads all the performance meter registers in the RSOP, RLOP, RPOP,
RXCP and TXCP.
TIP remains high while the transfer is in progress, and is set to a logic zero when the transfer
is complete. TIP can be polled by a microprocessor to determine when the accumulation
interval transfer is complete.
PCM:
The pointer concatenation mode select (PCM) determines the number of H1/H2 pointer pairs
used to determine loss of pointer concatenation (LOPC) and pointer AIS (AISC). When PCM
is set high, all H1/H2 pointer pairs are processed. When PCM is set low, only four H1/H2
pointer pairs (corresponding to the active STM-4-4c pointers) are processed.
PDLE:
The Parallel Diagnostic Loopback, PDLE bit enables the S/UNI-622-MAX diagnostic loopback
where the S/UNI-622-MAX’s Transmit Section Overhead Processor (TSOP) is directly
connected to its Receive Section Overhead Processor (RSOP). When PDLE is logic one,
loopback is enabled. Under this operating condition, the S/UNI-622-MAX continues to
operates normally in the transmit direction. When PDLE is logic zero, the S/UNI-622-MAX
operates normally in both directions.
DLE:
The Diagnostic Loopback, DLE bit enables the S/UNI-622-MAX diagnostic loopback where
the S/UNI-622-MAX’s Transmit are directly connected to the Receive ATM. When DLE is
logic one, loopback is enabled. Under this operating condition, the S/UNI-622-MAX does not
