15.5.4 DS3-12 and DS3N-12 Card Performance Monitoring Parameters
15.5.3.1 DS-1 Facility Data Link Performance Monitoring
Facility Data Link (FDL) performance monitoring enables an ONS 15454 DS1N -14 card to calculate and
report DS-1 error rate performance measured at both the near-end and far-end of the FDL. The far-end
information is reported as received on the FDL in a performance report message (PRM) from an
intelligent channel service unit (CSU).
To monitor DS-1 FDL PM values, the DS-1 must be set to use ESF format and the FDL must be
connected to an intelligent CSU. For procedures for provisioning ESF on the DS1N-14 card, refer to the
Cisco ONS 15454 Procedure Guide.
The monitored DS-1 FDL PM parameters are CV-PFE, ES-PFE, ESA-PFE, ESB-PFE, SES-PFE,
SEFS-PFE, CSS-PFE, UAS-PFE, FC-PFE, and ES-LFE. See Table 15-3 on page 15-5 for detailed
information and definitions of specific FDL DS1 PM parameters.
15.5.4 DS3-12 and DS3N-12 Card Performance Monitoring Parameters
Figure 15-8 shows the signal types that support near-end and far-end PMs. Figure 15-9 shows where
overhead bytes detected on the ASICs produce PM parameters for the DS3 -12 and DS3N-12 cards.
