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. |

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:
|
Line status | Read only | Specifies the line status of the ATM Port. One or more of the following values may be set:
|
Deactivation mode | Change | Specifies how child objects should be deactivated when deactivating this object. Values:
|
Alarm state | Read only | Specifies whether any alarms are currently raised for this object. Values:
|
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:
|
Actual status | Read only | Specifies the current status of the port. Values:
|
