Degraded

 

A Degraded Minute is calculated by collecting all of the available seconds,

 

 

 

Minutes

 

subtracting any SESs and sorting the result in 60 second groups

 

 

 

 

 

A Degraded Minute is a 60 second group in which the cumulative errors

 

 

 

 

 

during the 60-second interval exceed 1x10-6

 

 

 

 

 

T1-ESF or E1-CRC4 modes

Description

 

 

 

 

 

 

 

Valid Intervals

 

Number of 15-minute intervals stored in the system since power-up

 

 

 

 

 

 

 

Time Since

 

Elapsed time since the beginning of the current interval

 

 

 

 

(interval 0). This is displayed only when the current interval is monitored.

 

 

 

 

 

 

 

Interval Number

 

Number of the interval to be displayed

 

 

 

 

Interval number 0 (zero) is the current interval. The current interval display is

 

 

 

 

continuously updated. The elapsed time since the beginning of the interval is

 

 

 

 

displayed.

 

 

 

 

 

 

 

Start Time

 

Time and date when the monitored interval started

 

 

 

 

Displayed only when viewing previous intervals.

 

 

 

 

 

 

 

Prev

 

Displays the previous interval

 

 

 

 

From the first interval (current interval = 0) Prev is not visible.

 

 

 

 

 

 

 

Next

 

Displays the next interval

 

 

 

 

The number of valid intervals is displayed. From the last valid interval Next is not

 

 

 

 

visible.
