- An errored second occurs when either (1) the CRC does not match
the calculated CRC or (2) when the line is linked up but lacking synchronization. Whether 1 error up to 81
errors occur within a second, it will still be 1 errored second.

- A severely errored second is defined for one iDSL line
as a second containing more than 82 CRC errors. The SES counter will not be incremented when the box
is incrementing the

- Unavailable seconds is an indication of the amount of
time that an iDSL port is activated but not available for data transmission. 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 if
the 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.

Clicking on the
/ %
link displays the
/ %
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
/ %
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, and
UAS have occurred in the 15 minute intervals. The maximum number of intervals is 96 which is one 24-hour
time period. (15minutes* 96 = 24hours). The
/ %
page always records the last 24 hours error performance
of 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 Information
The
& &
is the same as the
! &
shown on the main page, it allows users to enter
an ID to represent the iDSL port.
