Line


The Line subtab allows you to provision the STM-N card line parameters.

Item

Description

Port

The card port number.

Port Name

Allows you to enter a port name.

Admin State

The port administration state. Choosing an administrative state from the drop-down list and clicking Apply changes the port's service state unless network conditions prevent the change. Admin states include:

  • unlocked: Puts the port in-service. The port service state changes to unlocked-enabled.

  • locked,disabled: Removes the port from service and disables it. The port service state changes to locked-enabled,disabled.

  • locked,maintenance: Removes the port from service for maintenance. The port service state changes to locked-enabled,maintenance.

  • unlocked,automaticInService: Puts the port in automatic in-service. The port service state changes to unlocked-disabled,automaticInService.

Service State

An autonomously generated state that gives the overall condition of the port. Service states appear in the format: Primary State-Primary State Qualifier, Secondary State. Port service states include:

  • unlocked-enabled: The port is fully operational and performing as provisioned.

  • locked-enabled,disabled: The port is out-of-service and unable to carry traffic.

  • locked-enabled,maintenance: The port is out-of-service for maintenance. Alarm reporting is suppressed, but traffic is carried and loopbacks are allowed.

  • unlocked-disabled,automaticInService: The port is out-of-service, but traffic is carried. Alarm reporting is suppressed. The ONS node monitors the ports for an error-free signal. After an error-free signal is detected, the port stays in unlocked-disabled,automaticInService state for the duration of the soak period. After the soak period ends, the port service state changes to unlocked-enabled.

SF BER

Sets the signal failure bit error rate.

SD BER

Sets the signal degrade bit error rate.

MS-SPRing Ext. Byte

Allows you to change the extension byte to K3, Z2, E2, or F1.

Provides Sync

If checked, the card is provisioned as an NE timing reference.

Sync Msg In

Enables synchronization status messages (S1 byte), which allow the node to choose the best timing source.

Admin SSM In

If the node does not receive an SSM signal, it defaults to STU (synchronization traceability unknown). Admin SSM allows you to override the STU value with one of the following: G811, STU, G812T, G812L, SETS, and DUS. The Admin SSM is a list of all SSM levels. You cannot select Admin SSM In if Sync Message In is enabled on the STM-N card.

Send <FF> DoNotUse

When checked, sends a DUS (do not use) message that allows the S1 byte to be set with 0xFF.

Send Do Not Use

When checked, sends a DUS (do not use) message on the S1 byte.

Type

Allows you to provision the STM-N cards for SDH or SONET.

PJVC4Mon#

Allows you to set the VC4 that will be used for monitoring pointer justification. If set to zero, no VC4 is used.

AINS Soak

Auto-in service soak. The determination of duration left before the traffic/termination transitions to unlocked-enabled service state.

ALS Mode

(STM-64 cards only.) Allows you to provision the automatic laser shutdown:

  • Disable: ALS is off; the laser is not automatically shut down when traffic outages (LOS) occur.

  • Auto Restart: ALS is on; the laser automatically shuts down when traffic outages (LOS) occur. It automatically restarts when the conditions that caused the outage are resolved.

  • Manual Restart: ALS is on; the laser automatically shuts down when traffic outages (LOS) occur. However, the laser must be manually restarted when conditions that caused the outage are resolved.

  • Manual Restart for Test: Manually restarts the laser for testing.

Apply

Applies changes made to the fields in the tab.

Reset

Cancels any changes to the tab and returns the fields to their last-saved settings.
