The value MUST be the value of the XMPP.Connection.{i}.JabberID contained in the XMPP.Connection instance referenced by the ConnReqXMPPConnection parameter. If the ConnReqXMPPConnection parameter is empty or the XMPP.Connection instance being reference is disabled, then this value will be empty. If the XMPP.Connection instance being referenced by the ConnReqXMPPConnection parameter is lost (XMPP.Connection.{i}.Status parameter changes from Enabled to some other value), then the value of this parameter MUST remain unchanged until the connection can be reestablished and a new XMPP.Connection.{i}.JabberID can be established.

Active Notification requests for this parameter MAY be denied.

[Alias] A non-volatile handle used to reference this instance. Alias provides a mechanism for an ACS to label this instance for future reference.

If the CPE supports the Alias-based Addressing feature as defined in [Section 3.6.1/TR-069] and described in [Appendix II/TR-069], the following mandatory constraints MUST be enforced:

• Its value MUST NOT be empty.
• Its value MUST start with a letter.
• If its value is not assigned by the ACS, it MUST start with a “cpe-” prefix.
• The CPE MUST NOT change the parameter value.

The Agent MUST choose an initial value that doesn’t conflict with any existing entries.

Active Notification requests for this parameter MAY be denied.

Controls how this parameter’s value is sampled. Enumeration of:

• Current (Sampled value is current value)
• Change (Sampled value is change in value since start of sample interval) Parameters of non-numeric types can only support Current. The value of the SampleMode MUST be ignored for such parameters.

Controls how this parameter’s statistic is calculated from the sampled value(s). Enumeration of:

• Latest (Statistic is sampled value at end of sample interval)
• Minimum (Statistic is minimum sampled value during sample interval)
• Maximum (Statistic is maximum sampled value during sample interval)
• Average (Statistic is average (mean) sampled value during sample interval) Parameters of non-numeric types can only support Latest. The value of the CalculationMode MUST be ignored for such parameters. SampleMode MUST be applied before CalculationMode, i.e. the inputs to the calculation will have already accounted for SampleMode.

Comma-separated list of unsigned integers. Each entry indicates the number of seconds during which data was collected for this parameter during the sample interval. Individual SampleSeconds values can be less than PeriodicStatistics.SampleSet.{i}.SampleInterval, for several reasons, including:

Any of the reasons for which PeriodicStatistics.SampleSet.{i}.SampleSeconds values might be less than PeriodicStatistics.SampleSet.{i}.SampleInterval.

The parameter doesn’t exist, or was created or deleted during a sample interval.

Active Notification requests for this parameter MAY be denied.

Comma-separated list of unsigned integers (up to 1). Each entry is 0 if the sampled value is believed to be valid, or 1 if an event that might affect the validity of the sampled value occurred during the sample interval. For example, if the parameter value were to be reset during the sample interval then it would be appropriate to set SuspectData to 1.

Active Notification requests for this parameter MAY be denied.

Comma-separated list of strings. Each entry indicates the value of the referenced parameter, as determined by SampleMode, during the sample interval. The statistics values in this comma-separated lists MUST be in time order, with the oldest one first and the most recent one last. If the SampleMode parameter is not present, or is inappropriate for the referenced parameter, the statistics values MUST be collected in Current mode.

Active Notification requests for this parameter MAY be denied.

• “in range” : current value is greater than LowThreshold and less than HighThreshold.
• “out of range” : current value is less than or equal to LowThreshold, or greater than or equal to HighThreshold.
• “out of range (low)” : current value is less than or equal to LowThreshold.
• “out of range (high)” : current value is greater than or equal to HighThreshold. Note that, if LowThreshold and HighThreshold are both the same, the threshold/failure mechanism is disabled, so the value of this parameter will not increment. This parameter can be incremented at any time during a sample interval, and might be incremented more than once during a single sample interval. For this reason, the CPE SHOULD place a locally specified limit on the frequency at which it will notify the ACS of such changes, as described in [Section 3.2.1/TR-069a2]. Parameters of non-numeric types cannot support the threshold/failure mechanism. The value of this parameter MUST be ignored for such parameters.

The status of the announcement service.

Enumeration of:

• Disabled
• Enabled
• Error (MAY be used by the CPE to indicate a locally defined error condition, OPTIONAL)

[Alias] A non-volatile handle used to reference this instance. Alias provides a mechanism for an ACS to label this instance for future reference.

Active Notification requests for this parameter MAY be denied.

The status of this group table entry.

Enumeration of:

• Disabled
• Enabled
• Error (MAY be used by the CPE to indicate a locally defined error condition, e.g. unable to parse received announcements, OPTIONAL)

The status of the query service.

Enumeration of:

• Disabled
• Enabled
• Error (MAY be used by the CPE to indicate a locally defined error condition, e.g. unable to contact query response server, OPTIONAL)

Indicates the status of this ExecEnv.

Enumeration of:

• Up
• Error (OPTIONAL)
• Disabled

1. All Deployment Units that were installed after the last “0 BOOTSTRAP” Inform event MUST be removed
2. All persistent storage, configuration files, and log files that were associated with the removed Deployment Units MUST be removed
3. Any Deployment Unit that is still installed against the Execution Environment MUST be restored to the version present when the last “0 BOOTSTRAP” Inform event was issued
4. Any Deployment Unit that was present when the last “0 BOOTSTRAP” Inform event was issued, but was subsequently uninstalled and is now not present, MUST be installed with the version that was present when the last “0 BOOTSTRAP” Inform event was issued
5. The Execution Environment MUST be restored to the version and configuration present when the last “0 BOOTSTRAP” Inform event was issued
6. The Execution Environment MUST be restarted after all other restoration requirements have been met

Active Notification requests for this parameter MAY be denied.

The amount of disk space measured in kilobytes currently available to this ExecEnv. This value changes as the ExecutionUnit instances associated with this ExecEnv consumes disk space. A value of -1 MUST be used for ExecEnv instances where this parameter is not applicable.

Active Notification requests for this parameter MAY be denied.

The amount of physical RAM measured in kilobytes currently available to this ExecEnv. This value changes as the ExecutionUnit instances associated with this ExecEnv are started/stopped and consume the physical RAM. A value of -1 MUST be used for ExecEnv instances where this parameter is not applicable.

Active Notification requests for this parameter MAY be denied.

Comma-separated list of strings. Each list item MUST be the Path Name of a row in the ExecutionUnit. table. If the referenced object is deleted, the corresponding item MUST be removed from the list. Represents the ExecutionUnit instances currently running on this ExecEnv. This parameter only contains ExecutionUnit instances that currently have a ExecutionUnit.{i}.Status of Active.

Active Notification requests for this parameter MAY be denied.

Indicates the status of this DeploymentUnit.

Enumeration of:

• Installing (This instance is in the process of being Installed and SHOULD transition to the Installed state)
• Installed (This instance has been successfully Installed. The Resolved flag SHOULD also be referenced for dependency resolution)
• Updating (This instance is in the process of being Updated and SHOULD transition to the Installed state)
• Uninstalling (This instance is in the process of being Uninstalled and SHOULD transition to the Uninstalled state)
• Uninstalled (This instance has been successfully Uninstalled. This status will typically not be seen within a DeploymentUnit instance)
