ATM Port

The ATM Port object describes a port (physical interface) on an ATM communications card.

You can enable the port using the Enable button if it is disabled, and activate it using the Activate button.

Each ATM Port object is a child of an Adaptor object with adaptor type PB1000 ATM Card.

In the EMS System Explorer, the name shown for each ATM Port indicates

For example, 'ATM Port (Shelf A, Slot 1, Port 1)'.


The deactivation mode for an ATM Port is always Normal, and so there is no Deactivation mode option. Quiesce mode deactivation is available on the associated Fault Tolerant ATM Port.

Parameter

Access

Description
Min VPI Change Inactive The lowest VPI value that can be assigned to circuits using this port. When configuring a DSLAM to access this port, each circuit used by the DSLAM must have a VPI value in the range specified by Min VPI and Number of bits for VPI. Range: 0 - 255. The default is 0.
Number of bits for VPI Change Inactive The number of bits available for encoding VPI values on this port. Range: 0 - 8. The default is 2.
Min VCI Change Inactive The lowest VCI value that can be assigned to circuits using this port. When configuring a DSLAM to access this port, each circuit used by the DSLAM must have a VCI value in the range specified by Min VCI and Number of bits for VCI. Range: 64 - 65535. The default is 64.
Number of bits for VCI Change Inactive The number of bits available for encoding VCI values on this port. Range: 0 - 16. The default is 8.
Min AAL2 Circuit ID Change Inactive The lowest AAL2 Circuit ID value available on this port for audio data (not the LES/EOC channel). Range: 16 - 127. The default is 16.
Number of bits for AAL2 Circuits Change Inactive The number of bits available for encoding AAL2 Circuit IDs on this port. Range: 0 - 8. The default is 3.
LES/EOC channel required Change Inactive Specifies whether the LES/EOC channel is required on this ATM Port. Values:
  • True
  • False (default)
Line status Read only Specifies the line status of the ATM Port. One or more of the following values may be set:
  • Sonet LOS
    Loss of signal (signal amplitude has dropped below prescribed limits for a period of time).
  • Sonet LOF
    Loss of frame (OOF state persisting for a period of time).
  • Sonet LOP
    Loss of pointer (consecutive occurrences of conditions that are deemed to cause the value of the pointer to be unknown).
  • AIS
    Alarm indication signal (a remote fault is affecting data that would otherwise be received at this port).
  • RDI
    Remote defect indication (a remote fault is affecting data being transmitted from this port).
  • Path AIS
    Alarm indication signal, but specific to a more remote failure in an optical network.
  • Path RDI
    Remote defect indication, but specific to a more remote failure in an optical network.
Deactivation mode Change Specifies how child objects should be deactivated when deactivating this object. Values:
  • Normal (default)
    Shut down child objects normally before deactivating the object.
  • Quiesce
    Wait for existing child objects to become inactive before deactivating the object, but do not allow any new child objects to be activated.
  • Abort
    Deactivate the object and all its child objects immediately. (This may result in errors at remote systems.)
Alarm state Read only Specifies whether any alarms are currently raised for this object. Values:
  • Clear
    No alarms are currently raised.
  • Attention Required
    Attention Required - the object is not operating normally, and needs operator intervention.
  • Attend To Dependent
    Attention Required elsewhere - another object on which this object depends is not operating normally.
Alarm log correlator Read only Identifier of the log message for the event that caused the last Attention Required alarm state for this object. This field is reset when the Attention Required alarm events field is reset to zero.
Attention Required alarm events Read only / Reset Number of times (since the alarm count was reset) that this object's alarm state has gone to Attention Required.
Alarm state changed timestamp Read only The time (UTC) at which the Alarm state last changed.
Alarm events reset timestamp Read only The time (UTC) at which the Attention Required alarm events was last reset to zero.
Requested status Read only Specifies whether an administrator has attempted to activate the port. Values:
  • Active
    The object has been activated.
  • Inactive
    The object has not been activated or has been deactivated.
  • Disabled
    The object has been disabled.
Actual status Read only Specifies the current status of the port. Values:
  • Active
    The object is active.
  • Going Active
    Activation is in progress.
  • Going Inactive
    Deactivation is in progress.
  • Inactive
    The object is inactive.
  • Disabled
    The object has been disabled.
  • Activation Failed
    The object is inactive because an activation attempt has failed.
  • Failed
    The object was active but has failed.
  • Quiescing
    The object is preparing for normal deactivation. It is operating normally but will not accept any new users.
  • Waiting For Parent
    The object cannot be used because its parent object is not yet active.
  • Parent Failed
    The object cannot be used because its parent object has failed.
