Router(config-if)# pos delay triggers line ms

Specifies a delay for setting the line protocol to down when a line-level trigger alarm is received.

Router(config-if)# pos delay triggers path ms

Specifies that path-level alarms should act as triggers and specifies a delay for setting the line protocol to down when a path-level trigger alarm is received.

Router(config-if)# pos framing {sonet | sdh}

Specifies the POS framing type.

Router(config-if)# pos scramble-atm

Enables SONET payload scrambling.

Router(config-if)# pos threshold {b1-tca | b2-tca | b3-tca | sd-ber | sf-ber} rate
