Figure 15-7 shows where overhead bytes detected on the ASICs produce performance monitoring
parameters for the STM-1 and STM1 SH 1310-8 cards.
Figure 15-7 PM Read Points on the STM-1 and STM1 SH 1310-8 Cards
The PM parameters for the STM-1 and STM1 SH 1310-8 cards are described in Table 15-23 on
page 15-22 through Table 15-27 on page 15-24.

Table 15-23 Regenerator Section PM Parameters for the Near-End STM-1 and STM1 SH 1310-8 Cards
Parameter Definition
RS-EB Regenerator Section Errored Block (RS-EB) indicates that one or more
bits are in error within a block.
RS-BBE Regenerator Section Background Block Error (RS-BBE) is an errored
block not occurring as part of an SES.
RS-ES Regenerator Section Errored Second (RS-ES) is a one-second period with
one or more errored blocks or at least one defect.
RS-SES Regenerator Section Severely Errored Second (RS-SES) is a one-second
period which contains 30 percent or more errored blocks or at least one
defect. SES is a subset of ES.
