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.

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

MCSN

Monitoring cell sequence number. The sequence number of the performance monitoring 
cell (modulo 256).

Yes

Yes

TUC

0+1

Total user cell 0+1 count. Counts all user cells (modulo 65,536) sent before the FMC was 
inserted.

Yes

Yes

TUC

0

Total user cell 0 count. Counts CLP = 0 user cells (modulo 65,536) sent before the FMC 
was inserted.

Yes

Yes

TSTP

Time stamp. Used to indicate when the cell was inserted.

Yes

Yes

BEDC

0+1

Block error detection code. Even parity over the payload of the block of user cells sent 
since the last FMC.

No

Yes

TRCC

Total received cell count 0. Counts CLP=0 user cells (modulo 65,536) received before the 
FMC was received.

Yes

No

BLER

Block error result. Counts error parity bits detected by the BEDC of the received FMC.

Yes

No

0+1

Total received cell count 0+1. Counts all user cells (modulo 65,536) received before the 
FMC was received.
