29.6.6.1 Running a Performance Block Test
For bidirectional PM block tests, FMCs are monitored at the receive side and generated at
the transmit side. The following setup is required to run a bidirectional PM block test on an
active VCC:
1. Assign one of the available 64 performance monitoring tables by writing to both
RCT[PMT] and TCT[PMT] and initializing the one chosen. See Section 29.10.3,
ÒOAM Performance Monitoring Tables.Ó
2. For PM F5 segment termination set RCT[SEGF]; for PM F5 end-to-end termination
set RCT[ENDF].
3. Finally, set the channelÕs RCT[PM] and TCT[PM] and the receive raw cellÕs
RCT[PM].
For unidirectional PM block tests:
¥ For PM block monitoring only, set only the RCT Þelds above.
¥ For PM block generation only, set only the TCT Þelds above.
To run a block test on a VPC, assign all the VCCs of the tested VPC to the same
performance monitoring table. ConÞgure RCT[PMT] and TCT[PMT] to specify the
performance monitoring table associated with each F4 channel.
29.6.6.2 PM Block Monitoring
PM block monitoring is done by the receiver. After initialization (see Section 29.6.6.1),
whenever a cell is received for a VCC or VPC, the TRCC counters are incremented and the
