561221051L1-5, Issue 161221051L1-5ASeverely Errored Seconds (SES) AlarmThe locations shown in Figure 4 are monitored forSeverely Errored Seconds and counts are maintainedfor each location. If any of these counts exceed theSES programmed threshold (see Tables 1 and 2) analarm will be generated. This alarm threshold and thealarm type (minor or major) can be programmed bysetting switches S1 and S2 (Figure 2) to theappropriate positions according to Tables 1 and 2.The alarm thresholds are for the 15-minute registersonly, and the 15-minute SES counts are zeroed at each15-minute boundary. The SES alarm threshold andalarm type can also be configured in the Craftinterface Options Setup screen (see Figure 11).Unavailable Seconds (UAS) AlarmThe locations shown in Figure 4 are monitored forunavailable seconds. Seconds and counts aremaintained for each location. If any of these countsexceed the UAS programmed threshold (see Tables 1and 2), an alarm will be generated. This alarmthreshold and the alarm type (major or critical) can beprogrammed by setting switches S1 or S2 (Figure 2)to the appropriate positions according to Tables 1 and2. The alarm thresholds are for the 15-minuteregisters only, and the 15-minute UAS errored secondcounts are zeroed at each 15-minute boundary. TheUAS alarm threshold and alarm type can also beconfigured in the Craft interface Options Setup screen(see Figure 11). Note that HDSL2 two wire units onlyhave Loop 1.HFAC Alarm OutputsIf an HFAC is present in the shelf, alarm outputs areavailable on the backplane wirewrap pinscorresponding to the HFAC slot (see Figure 5).These outputs are dry contact relay connections andprovide normally open, normally closed and commonconnection points for alarm monitoring equipment.Alarm connection points corresponding to criticalmajor, and minor alarms (both visible and audible) areprovided. These alarms are generated by the HFAC asa result of processed data collected from the HTU-Cs /H2TU-Cs.Alarm outputs presented on these pins areprogrammable and can be provisioned in the HFACOptions Setup screen (see Options Setup screen), orusing the HFAC dip switch settings (see Tables 1, 2,and 3). Alarm severity can be provisioned for alarmsFigure 4.
