Excessive Error Rate Threshold

Possible Settings: 10E-4, 10E-5, 10E-6, 10E-7, 10E-8, 10E-9

Default Setting: 10E-4

Sets the error rate threshold that determines when an EER condition is declared. The excessive error rate is determined by the ratio of the number of CRC6 errors to the total number of bits received over a set period of time.

Display Conditions – This option only appears when Line Framing Format is set to ESF.

10E-4– Declares an EER if more than 1,535 CRC6 errors are detected in a 10 second period. Clears when fewer than 1,536 CRC6 errors are detected within the same time period.

10E-5– Declares an EER if more than 921 CRC6 errors are detected in a 60 second period or a 10-4condition occurs. Clears when fewer than 922 CRC6 errors are detected within the same time period.

10E-6– Declares an EER if more than 92 CRC6 errors are detected in a 60 second period or a 10-5or 10-4condition occurs. Clears when fewer than 93 CRC6 errors are detected within the same time period.

10E-7– Declares an EER if more than 9 CRC6 errors are detected in a 60 second period or a 10-6, or 10-5, or 10-4condition occurs. Clears when fewer than 10 CRC6 errors are detected within the same time period.

10E-8– Declares an EER if more than 41 CRC6 errors are detected in three 15 minute intervals or a 10-7, 10-6, 10-5, 10-4condition occurs. Clears when fewer than 42 CRC6 errors are detected within the same time period.

10E-9– Declares an EER if more than 4 CRC6 errors are detected in three 15 minute intervals or a 10-8, 10-7, 10-6, 10-5, or 10-4condition occurs. Clears when fewer than 5 CRC6 errors are detected within the same time period.

Circuit Identifier

Possible Settings: ASCII Text Entry, Clear

Default Setting: blank

Identifies the transmission vendor’s circuit information to facilitate troubleshooting.

ASCII Text Entry – Edit or display circuit identifier information (maximum 255 characters).

Clear – Removes the circuit identifier information.
