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

performance meter registers in the RSOP, RLOP, RPOP, SPTB, RXCP, TXCP

and TXFP blocks.

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 operate normally in

the transmit direction. When PDLE is logic zero, the S/UNI-622-MAX

operates normally in both directions.
