When equipped with VLNC2, VLNC35, and VLNC50/52/55 circuit packs, the line/port state provisioning feature is provided on Alcatel-Lucent 1850 TSS-5 NEs. This feature can help suppress alarm reporting and performance monitoring by supporting multiple states for high-speed OCn/STMn lines and electrical ports.
The following states are supported:
In the AUTO state, the line/port waits for the presence of a good signal (not LOS), and the line/port is not monitored/alarmed.
When a good signal (not LOS) is detected, the line/port automatically transitions from the AUTO state to the IS state, and the line/port is monitored/alarmed.
In the NMON state, the line/port is not monitored/alarmed and the line/port will not automatically transition to the IS state when a good signal (not LOS) is detected.
The user can submit commands to manually change a line/port from IS or AUTO to NMON, and from NMON to AUTO. A user cannot manually change from AUTO or NMON to IS.
