The Performance Data screens show the Errored (ES) and Unavailable Seconds (UAS) for both HDSL loops and
each E1 input at 15-minute intervals over a 4-hour time interval. Earlier and later data, in 4-hour time periods on
different span screens, can be accessed by pressing
(Previous) or
(Next) respectively. All Performance Data
counters can be set to zero by pressing
(Clear) from the ELU-319 List 5E and List 6E Span Status screen shown
in
Figure 16 on page 33
and
Figure 17 on page 34
.
Errored and Unavailable seconds are defined in
Table 16
.
.
From each Performance Data screen you can do the following:
•
Press
to view the previous 4-hour data screen.
•
Press
to view the next 4-hour data screen.
•
Press
to
exit.
•
Press
to view the next available span.
Since the ELU-319 is considered the master module, this clears all performance data screens
at both the ELU-319 and the ERU. The RS-232 interface at the ERU does not allow the counters
to be cleared.
