Performance-Monitoring Data Storage and
Reports 9
The FT-2000 OC-48 Lightwave System provides current quarter-hour and current
day registers for all accumulated performance parameters. There is also 1
previous day register and 32 previous quarter-hour registers (8 hours).
The FT-2000 OC-48 Lightwave System can initialize the current quarter-hour
and/or current day registers through the CIT locally or remotely at any time, as
well as retrieve and report the contents of any parameter storage register at any
time. When performance-monitoring data is retrieved, any previous day or
quarter-hour register with all zero data is not reported. The current day and
quarter-hour registers are always reported, even when they contain all zero data.
For more information, refer to the PERFORMANCE-Initialize-PM,
PERFORMANCE-Retrieve-PM-Line, PERFORMANCE-Retrieve-PM-Optics,
PERFORMANCE-Retrieve-PM-Section,
PERFORMANCE-Retrieve-PM-STS1, PERFORMANCE-Retrieve-PM-EC1,and
PERFORMANCE-Retrieve-PM-T3 inputs in Section 11, "Craft Interface Terminal
Usage."
A single start time can be provisioned for measuring all the current day
performance-monitoring parameters. The start time can be provisioned to start at
any hour. The performance-monitoring parameters will reset and begin daily at the
provisioned start time. For more information about provisioning the
performance-monitoring start time, refer to Volume I, Section 8, "Administration
and Provisioning."
Performance Monitoring During Failed
Conditions 9
When a trouble condition is detected, the FT-2000 OC-48 Lightwave System
stops accumulating affected performance parameters per Telcordia requirements.
All unaffected performance parameters continue to be accumulated during the
trouble condition.
The coding violations (CV) and errored seconds (ES) counts are accumulated
until a severely errored second (SES) is counted. When a severely errored
second (SES) is counted, the coding violations (CV) count is inhibited. The
errored seconds (ES) and severely errored seconds (SES) counts continue to be
accumulated until an unavailable second (UAS) is counted. When an unavailable
second (UAS) is counted, the coding violations (CV), errored seconds (ES), and
severely errored seconds (SES) counts are inhibited.
The unavailable seconds (UAS) and protection switch count (PSC-L) parameter
counts are not inhibited.
