Use the Line > SDH subtab to provision the TXP and MXP the payload line parameters. The payload type shown on subtab names depends on the payload data type provisioned on the PPM (plugable port module) tab.

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.

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

  • 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.

Service State

An autonomously generated state that gives the overall condition of the port. Service states appear in the format: Administrative State-Operational State, Status Attribute. Port service states include:

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

  • 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.

  • 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.

SF BER

Signal failure bit error rate. (This field cannot be changed.)

SD BER

Sets the signal degrade bit error rate.

AINS Soak

Automatic In-Service soak time. The duration of time that must pass with an uninterrupted signal before the traffic/termination transitions to the unlocked-enabled service state.

Type

The signal type, either SDH or SONET.

ALS Mode

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.

Provides Sync

(TXP_MR_10E only.) If checked, the card is provisioned as a network element (NE) timing reference.

SyncMsgIn

(TXP_MR_10E only.) Enables synchronization status messages (S1 byte), which allow the node to choose the best timing source.

Send DoNotUse

(TXP_MR_10E only.) When checked, sends a DUS (do not use) message on the S1 byte.

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.

Help

Displays context-sensitive help.
