When set to true, resets the SmartCard Reader and the associated SmartCard.

When read, this parameter returns false, regardless of the actual value.

• Status transition from Disabled to Enabled
• Reset set to true.
• An internal reset of the SmartCard Reader (including a reboot of the device). Unknown Time value indicates that this SmartCard Reader has never been reset, which can only happen if it has never been enabled.

Counter incremented once each time decryption cannot be carried out. This counter relates to the smart card reader, not to the smart card itself, i.e. it is reset when the Reset parameter is used and not when a Smart Card is inserted or removed.

Active Notification requests for this parameter MAY be denied.

Counter incremented once each time the key is not available to decrypt it. This is a subset of the more general DecryptionFailedCounter within the same object and thus will always be less than that parameter.

To ensure the use of the proper test parameters (the writable parameters in this object), the test parameters MUST be set either prior to or at the same time as (in the same SetParameterValues) setting the DiagnosticsState to Requested. When requested, the CPE SHOULD wait until after completion of the communication session with the ACS before starting the diagnostic. When the test is completed, the value of this parameter MUST be either Complete (if the test completed successfully), or one of the Error values listed above. If the value of this parameter is anything other than Complete, the values of the results parameters for this test are indeterminate. When the diagnostic initiated by the ACS is completed (successfully or not), the CPE MUST establish a new connection to the ACS to allow the ACS to view the results, indicating the Event code “8 DIAGNOSTICS COMPLETE” in the Inform message. After the diagnostic is complete, the value of all result parameters (all read-only parameters in this object) MUST be retained by the CPE until either this diagnostic is run again, or the CPE reboots. After a reboot, if the CPE has not retained the result parameters from the most recent test, it MUST set the value of this parameter to None. Modifying any of the writable parameters in this object except for this one MUST result in the value of this parameter being set to None. While the test is in progress, modifying any of the writable parameters in this object except for this one MUST result in the test being terminated and the value of this parameter being set to None. While the test is in progress, setting this parameter to Requested (and possibly modifying other writable parameters in this object) MUST result in the test being terminated and then restarted using the current values of the test parameters.

• Trigger (Collection is enabled and the ACS SHOULD now fetch the collected data) The Trigger value is only used for triggering the ACS to fetch the collected data and can only be used when FetchSamples is in the range [1:ReportSamples]. The transition from Enabled to Trigger to Enabled MUST be instantaneous and so will result in only a single value change for notification purposes.

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

TimeReference has been set to a time other than the Unknown Time and the current sample interval started part of the way through a scheduled sample interval.

ForceSample has been used to force statistics for the current sample to be calculated and updated in the data model.

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 {{param: non-existent .PeriodicStatistics.SampleSet.{i}.SampleInterval}}, for several reasons, including:

Any of the reasons for which {{param: non-existent .PeriodicStatistics.SampleSet.{i}.SampleSeconds}} values might be less than {{param: non-existent .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.

• 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
