pm stm

To configure the pm parameters of an STM controller, use the pm command in the config mode. To delete the pm parameters of an STM controller, use the no form of this command.

pm [ 15-min | 24-hour] { stm} [ report status | threshold value]

no pm [ 15-min | 24-hour] { stm} [ report status | threshold value]

Syntax Description

Configures the 24 hour time interval for the PM parameters.

stm

Displays the name of the layer.

report

Configures the TCA reporting status of the controller.

report status

threshold

To configure threshold for B3 bit error rate (BER) threshold crossing alert (TCA) on a STMn controller, use the threshold command in the config mode. To delete the threshold for B3 BER TCA from a STMn controller, use the no form of this command.

threshold { b1-tca | b2-tca | sd-ber | sf-ber} value

no threshold { b1-tca | b2-tca | sd-ber | sf-ber} value

Syntax Description

b1-tca

Configures the B1 BER threshold for the TCA on the STMn controller.

b2-tca

Configures the B2 BER threshold for the TCA on the STMn controller.

sd-ber

Configures the signal degrade BER threshold on the STMn controller.

sf-ber

Configures the signal fail BER threshold on the STMn controller.

value

Configures the BER value. The BER value ranges from 3 to 9 and default value is 6 for b1-tca and b2-tca. For sd-ber it ranges from 5 to 9 and default value is 6. BER value for sf-ber ranges from 3 to 5 and default value is 3.

Command Default

TCA threshold : B1=10e-6 B2=10e-6
