Threshold Value UAS

Range:

1 to 255

 

 

 

Default:

1

 

 

 

Description:

Specifies the number of errors that must occur within a fixed

 

15- minute window before an alarm is declared. This is based on

 

the threshold value for Unavailable Seconds. The DS1 interface is

 

unavailable from the onset of 10 contiguous SESs or any condition

 

leading to a failure;

 

• once unavailable and if no failure is present, the DS1 interface

 

becomes available at the onset of 10 contiguous seconds with

 

no SESs

 

• once unavailable and if a failure is present, the DS1 interface

 

becomes available at the onset of 10 contiguous seconds with

 

no SESs if the failure clearing time is less than or equal to 10

 

seconds

 

• once unavailable and if a failure is present, the DS1 interface

 

becomes available at

 

the onset of 10 contiguous seconds with no SESs if the

 

 

failure clearing time is more than 10 seconds

 

or the onset period leading to the successful clearing

 

 

condition, whichever occurs later
