Threshold Value-ES

Range:

1 to 255

 

 

Default:

10

 

 

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 Error Seconds, which have:

 

• one or more path code violations

 

• one or more out-of-frame defects

 

• one or more controlled slip events

 

• a detected alarm indication signal defect

 

For D4 and E1-CRC links, the presence of bipolar violations also

 

triggers an errored second.

 

 

Threshold Value-BES

 

 

Range:

1 to 255

 

 

Default:

10

 

 

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 Bursty Errored Seconds, which have:

 

• fewer than 320 and more than 1 path coding violation error

 

events

 

• no severely errored frame defects

 

• no detected incoming alarm indication signal defects

 

Controlled slips are not included; BES is not incremented during

 

an unavailable second.
