Motorola T3 Power Broadband manual Line Quality

System Administration

Line Quality

T3 includes Forward Error Correction in the VDSL frames. Bit errors that are not corrected are counted and reported as a Line Quality measurement. Bit errors are averaged over 1 second of time. An SNMP trap will be sent to the SNMP trap recipient when the threshold is crossed. The line quality status will change in the webUI and the Command Line Interface. There are two thresholds that will be set:

Maximum threshold – the line quality status will change to Fair when the errors increase beyond the maximum threshold

Minimum threshold – the line quality status will change to Good when the errors decrease below the minimum threshold

To set the line quality threshold, use the following command:

interface dsl thresholds min-threshold <0.5 to 50> max-threshold <0.5 to 50>

Line quality threshold can also be set from the webUI using the Interface DSL menu

By default, the thresholds are set to:

min-threshold	1.7 bit errors/second
max-threshold	2 bit errors/second
