Performance Monitoring Data Storage and Reports 9
The DDM-2000 OC-3 Multiplexer provides current quarter-hour and current day
registers for all accumulated performance parameters. Previous day and previous
quarter-hour registers for the preceding 8 hours also are provided for all
accumulated performance parameters.
The DDM-2000 OC-3 Multiplexer has the capability to initialize the current
registers through the CIT locally or remotely at any time, as well as to report the
contents of any register at any time. Refer to the init-pm, rtrv-pm-line,
rtrv-pm-sect, rtrv-pm-sts1, rtrv-pm-t1, rtrv-pm-t3, and rtrv-pm-
tca commands in Section 11, "Commands and Reports."
Performance Monitoring During Failed Conditions 9
When the DDM-2000 OC-3 Multiplexer detects a trouble condition, the system
stops accumulating affected performance parameters. Parameters that continue
to provide useful information are accumulated during the trouble condition.
Performance Parameter Thresholds 9
The DDM-2000 OC-3 Multiplexer provides performance thresholds to alert
maintenance staff of degraded transmission. Whenever the threshold for a
parameter is exceeded, the DDM-2000 OC-3 Multiplexer generates a TCA to alert
the OS to the condition. A summary of all TCAs is available in the PM TCA
summary report. Current quarter-hour and current day thresholds for each
parameter are provisionable, via the CIT, on a per-shelf basis. Therefore, if values
other than the defaults are to be used, only one value needs to be set for each
parameter. Generation of TCAs can be disabled independently for each
performance parameter. Performance data is still collected if thresholding is
disabled. Refer to the rtrv-pmthres-line, rtrv-pmthres-sect, rtrv-
pmthres-sts1, rtrv-pmthres-t3, set-pmthres-line, set-pmthres-
sect, set-pmthres-sts1, set-pmthres-t3, rtrv-pm-tca, rtrv-
pmthres-vt1, rtrv-pmthres-t1, set-pmthres-vt1, and set-pmthres-
t1 commands in Section 11, "Commands and Reports."
