The UAS counter is incre-mented under the following criteria:1.The port must be activated.2.Once the port is activated and a link-up timer has expired, the UAS counter will be incremented ifthe ports loses sync or does not enter synchronization with the far end of the link.3.Once the port gains link status, the 3092 begins looking for ES and SES.4.Upon receiving 10 consecutive SES or a line down indication, the 3092 will begin reporting UAS.The 3092 will not increment ES or SES during the UAS count.5.The UAS count will stop when 10 consecutive seconds without an SES is detected.)LJXUH+LVWRU\RI1HDU(QG3HUIRUPDQ HZLQGRZClicking on the +LVWRU\ link displays the +LVWRU\RI1HDU(QG3HUIRUPDQ H window (see Figure 18), which dis-plays the cumulative statistics for each of the 15-minute intervals. The most recent 15-minute interval is num-bered 1. The maximum of 15-minute intervals is 96.The +LVWRU\ page collects and records the error history of the port. Interval 1 is the history of the most recent,completed 15-minute interval. The length of each interval is 15 minutes. and records how many ES, SES, andUAS have occurred in the 15 minute intervals. The maximum number of intervals is 96 which is one 24-hourtime period. (15minutes* 96 = 24hours). The +LVWRU\ page always records the last 24 hours error performanceof the port. Information older than 24 hours will not be shown and will be erased. In the example page above,only 5 intervals of information are available, so the page will only show 5 intervals.Port Identification InformationThe 3RUW,GHQWLIL DWLRQ,QIRUPDWLRQ is the same as the &LU XLW,' shown on the main page, it allows users to enteran ID to represent the iDSL port.
