29.10.3 OAM Performance Monitoring Tables
The OAM performance monitoring tables include performance monitoring block test
parameters, as shown in Figure 29-37. Each block test needs a 32-byte performance
monitoring table in the dual-port RAM. In the connectionÕs RCT and TCT, the user
allocates an OAM performance table to a VCC or VPC. See Section 29.6.6, ÒPerformance
Monitoring.Ó PMT_BASE in the parameter RAM points to the base address of the tables.
The starting address of each PM table is given by PMT_BASE + RCT/TCT[PMT]
´ 32.
Table 29-28 describes Þelds in the performance monitoring table.
