Root data model version, e.g. 2.4. For a vendor-defined root data model, this is the standard Broadband Forum model on which the vendor-defined model is based. Possible patterns:

• 2.\d+

Comma-separated list of strings. Each list item is a device category (e.g. “AV_TV” and “AV_Recorder”), or the value is an empty string if no such element is provided by the device.

Note: It is assumed that this list might be used for HTIP (Home-network Topology Identifying Protocol) [JJ-300.00] and [G.9973]. Standard HTIP device categories are defined in [JJ-300.01]. In this case, the maximum length of the list is 127 and of each item is 31, and any non-HTIP device categories SHOULD NOT conflict with standard HTIP device categories.

Organizationally unique identifier of the device manufacturer. Represented as a six hexadecimal-digit value using all upper-case letters and including any leading zeros. Possible patterns:

• [0-9A-F]{6}

The value MUST be a valid OUI as defined in [OUI].

This value MUST remain fixed over the lifetime of the device, including across firmware updates.

Any change would indicate that it’s a new device and would therefore require a BOOTSTRAP Inform.

The model number of the device (human readable string), or an empty string if no model number is provided by the device.

Note: It is assumed that this string might be used for HTIP (Home-network Topology Identifying Protocol) [JJ-300.00] and [G.9973]. In this case, the maximum length of the string is 31.

Identifier of the class of product for which the serial number applies. That is, for a given manufacturer, this parameter is used to identify the product or class of product over which the SerialNumber parameter is unique.

This value MUST remain fixed over the lifetime of the device, including across firmware updates.

Identifier of the particular device that is unique for the indicated class of product and manufacturer.

This value MUST remain fixed over the lifetime of the device, including across firmware updates.

A string identifying the software version currently installed in the CPE (i.e. version of the overall CPE firmware).

To allow version comparisons, this element SHOULD be in the form of dot-delimited integers, where each successive integer represents a more minor category of variation. For example, 3.0.21 where the components mean: Major.Minor.Build.

A full path reference to the row in the FirmwareImage table of the firmware image that is to be loaded the next time the device boots.

This parameter value cannot be empty and must point to a valid and enabled FirmwareImage object where the (FirmwareImage.{i}.Available parameter is set to ‘true’). Out of the factory, this parameter should be set to point to the firmware image the CPE will attempt to boot when first powered on.

The firmware image instance referenced by this parameter must also have an Available parameter value of ‘true’. Attempting to set this parameter to point to a non-enabled firmware image MUST result in the CPE responding with a CWMP fault (9007).

In situations where the CPE cannot boot the firmware image specified by this parameter and manages to boot a different firmware image, the CPE MUST NOT modify this value to point to the alternate firmware image that is currently active.

Date and time in UTC that the CPE first both successfully established an IP-layer network connection and acquired an absolute time reference using NTP or equivalent over that network connection. The CPE MAY reset this date after a factory reset.

If NTP or equivalent is not available, this parameter, if present, SHOULD be set to the Unknown Time value.

Enables and disables the CPE’s support for CWMP.

false means that CWMP support in the CPE is disabled, in which case the device MUST NOT send any Inform messages to the ACS or accept any Connection Request notifications from the ACS.

true means that CWMP support on the CPE is enabled.

The subscriber can re-enable the CPE’s CWMP support either by performing a factory reset or by using a LAN-side protocol to change the value of this parameter back to true.

The factory default value MUST be true.

The [URL] for the CPE to connect to the ACS using the CPE WAN Management Protocol.

This parameter MUST be in the form of a valid HTTP or HTTPS URL.

The host portion of this URL is used by the CPE for validating the ACS certificate when using SSL or TLS.

Note that on a factory reset of the CPE, the value of this parameter might be reset to its factory value. If an ACS modifies the value of this parameter, it SHOULD be prepared to accommodate the situation that the original value is restored as the result of a factory reset.

Username used to authenticate the CPE when making a connection to the ACS using the CPE WAN Management Protocol.

This username is used only for HTTP-based authentication of the CPE.

Note that on a factory reset of the CPE, the value of this parameter might be reset to its factory value. If an ACS modifies the value of this parameter, it SHOULD be prepared to accommodate the situation that the original value is restored as the result of a factory reset.

Password used to authenticate the CPE when making a connection to the ACS using the CPE WAN Management Protocol.

This password is used only for HTTP-based authentication of the CPE.

Note that on a factory reset of the CPE, the value of this parameter might be reset to its factory value. If an ACS modifies the value of this parameter, it SHOULD be prepared to accommodate the situation that the original value is restored as the result of a factory reset.

When read, this parameter returns an empty string, regardless of the actual value.

An absolute date and time in UTC at which time the CPE will perform a reboot.

If a CWMP session is in progress at the specified time, the CPE MUST wait until the session has ended before performing the reboot.

If the value specifies a date and time that has already passed (i.e., a past date and time), no reboot will be performed.

The number of seconds from the time the CWMP session in which this parameter value is set is ended until the CPE performs a reboot.

Whenever the CPE reboots, this value MUST be reset by the CPE to -1.

An absolute time reference in UTC to determine when the CPE will initiate the periodic Inform method calls. Each Inform call MUST occur at this reference time plus or minus an integer multiple of the PeriodicInformInterval.

PeriodicInformTime is used only to set the phase of the periodic Informs. The actual value of PeriodicInformTime can be arbitrarily far into the past or future.

For example, if PeriodicInformInterval is 86400 (a day) and if PeriodicInformTime is set to UTC midnight on some day (in the past, present, or future) then periodic Informs will occur every day at UTC midnight. These MUST begin on the very next midnight, even if PeriodicInformTime refers to a day in the future.

The Unknown Time value defined in [Section 3.2/TR-106] indicates that no particular time reference is specified. That is, the CPE MAY locally choose the time reference, and needs only to adhere to the specified PeriodicInformInterval.

If absolute time is not available to the CPE, its periodic Inform behavior MUST be the same as if the PeriodicInformTime parameter was set to the Unknown Time value.

ParameterKey provides the ACS a reliable and extensible means to track changes made by the ACS. The value of ParameterKey MUST be equal to the value of the ParameterKey argument from the most recent successful SetParameterValues, AddObject, or DeleteObject method call from the ACS.

The CPE MUST set ParameterKey to the value specified in the corresponding method arguments if and only if the method completes successfully and no fault response is generated. If a method call does not complete successfully (implying that the changes requested in the method did not take effect), the value of ParameterKey MUST NOT be modified.

The CPE MUST only modify the value of ParameterKey as a result of SetParameterValues, AddObject, DeleteObject, or due to a factory reset. On factory reset, the value of ParameterKey MUST be set to an empty string.

The HTTP [URL] for an ACS to make a Connection Request notification to the CPE.

In the form:

• http://host:port/path

The host portion of the URL MAY be the IP address for the management interface of the CPE in lieu of a host name.

Note: If the host portion of the URL is a literal IPv6 address then it MUST be enclosed in square brackets (see [Section 3.2.2/RFC3986]).

Password used to authenticate an ACS making a Connection Request to the CPE.

When read, this parameter returns an empty string, regardless of the actual value.

Indicates whether or not the ACS will manage upgrades for the CPE. If true, the CPE SHOULD NOT use other means other than the ACS to seek out available upgrades. If false, the CPE MAY use other means for this purpose.

Note that an autonomous upgrade (reported via an “10 AUTONOMOUS TRANSFER COMPLETE” Inform Event code) SHOULD be regarded as a managed upgrade if it is performed according to ACS-specified policy.

Present only for a CPE that supports the Kicked RPC method.

LAN-accessible [URL] from which the CPE can be kicked to initiate the Kicked RPC method call. MUST be an absolute URL including a host name or IP address as would be used on the LAN side of the CPE.

Present only for a CPE that provides a LAN-side web page to show progress during a file download.

LAN-accessible [URL] to which a web-server associated with the ACS MAY redirect a user’s browser on initiation of a file download to observer the status of the download.

This parameter is used to control throttling of active notifications sent by the CPE to the ACS. It defines the minimum number of seconds that the CPE MUST wait since the end of the last session with the ACS before establishing a new session for the purpose of delivering an active notification.

In other words, if CPE needs to establish a new session with the ACS for the sole purpose of delivering an active notification, it MUST delay establishing such a session as needed to ensure that the minimum time since the last session completion has been met.

The time is counted since the last successfully completed session, regardless of whether or not it was used for active notifications or other purposes. However, if connection to the ACS is established for purposes other than just delivering active notifications, including for the purpose of retrying a failed session, such connection MUST NOT be delayed based on this parameter value, and the pending active notifications MUST be communicated during that connection.

The time of the last session completion does not need to be tracked across reboots.

Configures the first session retry wait interval, in seconds, as specified in [Section 3.2.1.1/TR-069].

A value of 5 corresponds to the default behavior that is described in [TR-069].

The device MUST use a random value between CWMPRetryMinimumWaitInterval and (CWMPRetryMinimumWaitInterval * CWMPRetryIntervalMultiplier / 1000) as the first retry wait interval. Other values in the retry pattern MUST be calculated using this value as a starting point.

Configures the retry interval multiplier as specified in [Section 3.2.1.1/TR-069].

This value is expressed in units of 0.001. Hence the values of the multiplier range between 1.000 and 65.535.

A value of 2000 corresponds to the default behavior that is described in [TR-069].

The device MUST use a random value between CWMPRetryMinimumWaitInterval and (CWMPRetryMinimumWaitInterval * CWMPRetryIntervalMultiplier / 1000) as the first retry wait interval. Other values in the retry pattern MUST be calculated using this value as a starting point.

Enables or disables HTTP connection request handling on the CPE.

If HTTP connection request handling is disabled (HTTPConnectionRequestEnable is set to false), ConnectionRequestURL MUST be set to an empty string and the CPE MUST close the port used by the HTTP connection request server.

The factory default value MUST be true.

Address and port to which an ACS MAY send a UDP Connection Request to the CPE (see [Annex G/TR-069]).

This parameter is represented in the form of an Authority element as defined in [RFC3986]. The value MUST be in one of the following two forms:

• host:port
• host
• When STUNEnable is true, the host and port portions of this parameter MUST represent the public address and port corresponding to the NAT binding through which the ACS can send UDP Connection Request messages (once this information is learned by the CPE through the use of STUN).
• When STUNEnable is false, the host and port portions of the URL MUST represent the local IP address and port on which the CPE is listening for UDP Connection Request messages.

The second form of this parameter MAY be used only if the port value is equal to 80.

Note: If the host portion of the URL is a literal IPv6 address then it MUST be enclosed in square brackets (see [Section 3.2.2/RFC3986]).

Host name or IP address of the STUN server for the CPE to send Binding Requests if STUN is enabled via STUNEnable.

If is an empty string and STUNEnable is true, the CPE MUST use the address of the ACS extracted from the host portion of the ACS URL.

Port number of the STUN server for the CPE to send Binding Requests if STUN is enabled via STUNEnable.

By default, this SHOULD be the equal to the default STUN port, 3478.

If is not an empty string, the value of the STUN USERNAME attribute to be used in Binding Requests (only if message integrity has been requested by the STUN server).

If is an empty string, the CPE MUST NOT send STUN Binding Requests with message integrity.

The value of the STUN Password to be used in computing the MESSAGE-INTEGRITY attribute to be used in Binding Requests (only if message integrity has been requested by the STUN server).

When read, this parameter returns an empty string, regardless of the actual value.

If STUN Is enabled, the maximum period, in seconds, that STUN Binding Requests MUST be sent by the CPE for the purpose of maintaining the binding in the Gateway. This applies specifically to Binding Requests sent from the UDP Connection Request address and port.

A value of -1 indicates that no maximum period is specified.

When STUN is enabled, this parameter indicates whether or not the CPE has detected address and/or port mapping in use.

A true value indicates that the received MAPPED-ADDRESS in the most recent Binding Response differs from the CPE’s source address and port.

When STUNEnable is false, this value MUST be false.

Indicates whether or not the Alias-Based Addressing Mechanism is supported.

A true value indicates that the CPE supports the Alias-Based Addressing Mechanism, as defined in [Section 3.6.1/TR-069] and described in [Appendix II/TR-069].

Instance identification mode as defined in [Section 3.6.1/TR-069]. When AliasBasedAddressing is true, InstanceMode is used by the ACS to control whether the CPE will use Instance Numbers or Instance Aliases in returned Path Names. Enumeration of:

• InstanceNumber
• InstanceAlias

This parameter is REQUIRED for any CPE supporting Alias-Based Addressing.

The factory default value MUST be InstanceNumber.

Enable or disable the Auto-Create Instance Mechanism. When AliasBasedAddressing is true, AutoCreateInstances indicates whether or not the CPE will automatically create instances while processing a SetParameterValues RPC (as defined in [A.3.2.1/TR-069]).

*A true value indicates that the CPE will perform auto-creation of instances when the Alias-Based Addressing Mechanism is used in SetParameterValues RPC.

*A false value indicates that the CPE will not create new object instances. Instead, it will reject the setting of parameters in unrecognized instances and respond with a fault code.

This parameter is REQUIRED for any CPE supporting Alias-Based Addressing.

The factory default value MUST be false.

Comma-separated list of strings. The connection request methods supported by this Device.ManagementServer.. Each list item is an enumeration of:

• HTTP (The connection request method as specified in [Section 3.2.2 ACS Connection Initiation/TR-069], REQUIRED)
• STUN (The connection request method as specified in [Annex G Connection Request via NAT Gateway/TR-069], OPTIONAL)
• XMPP (The connection request method as specified in [Annex K XMPP Connection Request/TR-069], OPTIONAL)

When an XMPP Connection Request is sent to a CPE the XMPP IQ Stanza will contian a “from” address that contains the Jabber ID of the initiating entity.

This parameter is a Comma-separated list (length ) (up to 32 items) of strings (maximum number of characters per item 256). Each entry represents a Jabber ID, or address, that is allowed to initiate an XMPP Connection Request.

Each Jabber ID is allowed to be either a “Full JID” (containing a local-part, domain-part, and resource-part in the following format: “local-part@domain-part/resource-part”) or a “Bare JID” (containing a local-part and a domain-part in the following format: “local-part@domain-part”). “Full JID” entries require an exact match whereas “Bare JID” entries are a wildcard match and will match any Jabber ID with the same local-part and domain-part independent of the resource-part.

For example, if ConnReqAllowedJabberIDs contained “ACS1@tr069.example.com, ACS2@tr-069.example.com/resource1” then the following incoming “from” addresses would be allowed:

• “ACS1@tr069.example.com/resource1”
• “ACS1@tr069.example.com/resource2”
• “ACS2@tr069.example.com/resource1”

And the following incoming “from” addresses would not be allowed:

• “ACS2@tr069.example.com/resource2”
• “ACS@tr069.example.com/resource”

If this Parameter is an empty string then all Jabber IDs are allowed and an XMPP Connection Request can not be deemed invalid due to the “from” address.

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. If the new XMPP.Connection.{i}.JabberID is identical to the existing value, then the value of this parameter MUST NOT be altered and a VALUE CHANGE event MUST NOT be generated.

Comma-separated list of strings. Indicates the HTTP Compression mechanism(s) supported by this CPE. Requirements for the use of HTTP Compression for CWMP can be found in [Section 3.4.7/TR-069]. Each list item is an enumeration of:

• Compress (As defined in [Section 3.5/RFC2616])
• Deflate (As defined in [Section 3.5/RFC2616])

Vendors can extend the enumerated values with vendor specific extensions, in which case the rules outlined in [Section 3.3/TR-106] MUST be adhered to.

The value MUST be a member of the list reported by the HTTPCompressionSupported parameter, or else be Disabled. The value of this parameter represents the HTTP Compression mechanism to be used by the CPE when communicating with the ACS.

The factory default value MUST be Disabled.

Comma-separated list of strings. Indicates the Lightweight Notification Protocol(s) supported by this CPE. Each list item is an enumeration of:

• UDP (As defined in [Annex M/TR-069])

Comma-separated list of strings. Each list item MUST be a member of the list reported by the LightweightNotificationProtocolsSupported parameter, or else be an empty string. The value of this parameter represents the protocol(s) that will be used by the CPE when sending Lightweight Notifications.

An empty string means that Lightweight Notifications are disabled, despite any SetParameterAttributes that have been configured on various parameters.

The duration in seconds of the interval for which the CPE MUST attempt to deliver any pending Passive Lightweight Notifications.

A value of 0 means that the trigger interval is effectively disabled. In this case pending Passive Lightweight Notifications are only sent when triggered by an Active Lightweight Notification.

An absolute time reference in UTC to determine when the CPE will initiate the Lightweight Notification (in the case that there are pending Passive Lightweight Notifications that need to be delivered). Each Passive Lightweight Notification (that is waiting for the Lightweight Notification Trigger mechanism for delivery) MUST occur at this reference time plus or minus an integer multiple of the LightweightNotificationTriggerInterval. LightweightNotificationTriggerTime is used only to set the phase of the Passive Lightweight Notification. The actual value of LightweightNotificationTriggerTime can be arbitrarily far into the past or future.

For example, if LightweightNotificationTriggerInterval is 86400 (a day) and if LightweightNotificationTriggerTime is set to UTC midnight on some day (in the past, present, or future) then Lightweight Notifications for pending Passive Lightweight Notifications will occur every day at UTC midnight. These MUST begin on the very next midnight, even if LightweightNotificationTriggerTime refers to a day in the future. The Unknown Time value defined in [Section 3.2/TR-106] indicates that no particular time reference is specified. That is, the CPE MAY locally choose the time reference, and needs only to adhere to the specified LightweightNotificationTriggerInterval. If absolute time is not available to the CPE, its Lightweight Notifications behavior MUST be the same as if the LightweightNotificationTriggerTime parameter was set to the Unknown Time value.

Host name or address to be used when sending the UDP Lightweight Notifications.

UDPLightweightNotificationHost is only applicable when LightweightNotificationProtocolsUsed contains the UDP enumeration.

If UDPLightweightNotificationHost is not implemented or is an empty string, and UDP Lightweight Notifications are supported, the destination host MUST be the same as the ACS (as contained in the host portion of the URL).

The port number to be used when sending UDP Lightweight Notifications.

UDPLightweightNotificationPort is only applicable when LightweightNotificationProtocolsUsed contains the UDP enumeration.

If UDPLightweightNotificationPort is not implemented and UDP Lightweight Notifications are supported, the destination port MUST be 7547.

Indicates whether or not instance wildcards are supported.

A true value indicates that the CPE supports instance wildcards for GPV, GPN and GPA RPC calls, as defined in [TR-069].

Organizationally unique identifier of the Device manufacturer as provided to the Gateway by the Device. Represented as a six hexadecimal-digit value using all upper-case letters and including any leading zeros. Possible patterns:

• [0-9A-F]{6}

The value MUST be a valid OUI as defined in [OUI].

Identifier of the class of product for which the Device’s serial number applies as provided to the Gateway by the Device.

If the Device does not provide a Product Class, then this parameter MUST be an empty string.

Comma-separated list (maximum number of characters per item 1024) of strings. Each list item MUST be the Path Name of a row in the Hosts.Host. table. If the referenced object is deleted, the corresponding item MUST be removed from the list. References all the Hosts.Host table entries, whether active or inactive, that correspond to this physical LAN device. There can be multiple such entries if the device has more than one network interface.

For example: Device.Hosts.Host.1,Device.Hosts.Host.5

Indicates the transfer types that MUST be included when the CPE notifies the ACS of AUTONOMOUS TRANSFER COMPLETE events. Transfer types not indicated by this filter MUST NOT be included when the CPE notifies the ACS. Enumeration of:

• Both (Upload and Download)

Note that this includes any backup or restore operations that were not specifically requested by the ACS. A backup is regarded as an Upload and a restore is regarded as a Download.

Indicates the transfer results that MUST be included when the CPE notifies the ACS of AUTONOMOUS TRANSFER COMPLETE events. Transfer results omitted from this list MUST NOT be included when the CPE notifies the ACS.

Note that this includes any backup or restore operations that were not specifically requested by the ACS. A backup is regarded as an Upload and a restore is regarded as a Download. Enumeration of:

• Success (The autonomous file transfer completed successfully; i.e., the FaultCode was zero)
• Failure (The autonomous file transfer did not complete successfully; i.e., the FaultCode was non-zero)
• Both (Success and Failure)

Comma-separated list (maximum number of characters per item 1024) of strings. Indicates the file types that MUST be included when the CPE notifies the ACS of AUTONOMOUS TRANSFER COMPLETE events. File types omitted from this list MUST NOT be included when the CPE notifies the ACS.

Each list item matches one of:

• 1 Firmware Upgrade Image (Download Only)
• 2 Web Content (Download Only)
• 3 Vendor Configuration File (Download or Upload)
• 4 Vendor Log File (Upload Only)
• X [0-9A-F]{6} .* (For Vendor-Specific File Types, could be for either Download or Upload)

Additionally, the following format is defined to allow the unique definition of vendor-specific file types:

• “X <OUI> <Vendor-specific identifier>”

<OUI> is replaced by a 6 hexadecimal-digit OUI (organizationally unique identifier) as defined in [OUI], with all upper-case letters and any leading zeros included. The OUI used for a given vendor-specific file type MUST be one that is assigned to the organization that defined this file type (which is not necessarily the same as the vendor of the CPE or ACS).

Note that an empty string indicates that all file types are excluded from this filter, effectively disabling CPE notification of AUTONOMOUS TRANSFER COMPLETE events to the ACS.

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)

When waking up from a non CR-Aware Standby that lasted more than this parameter’s value (in seconds), the CPE MUST issue a WAKEUP Event.

If the value is -1, the CPE MUST NOT ever issue WAKEUP Events for having been non CR-aware.

The factory default value MUST be -1.

When waking up from a non fully Timer-Aware Standby that made it miss more than this parameter’s value Periodic Contacts, the CPE MUST issue a WAKEUP Event.

If the value is -1, the CPE MUST NOT ever issue WAKEUP Events for exceeding that limit.

The factory default value MUST be -1.

When waking up from a non fully Timer-Aware Standby that made it miss at least one Scheduled Contact, the CPE MUST issue a WAKEUP Event if this parameter is true.

The factory default value MUST be false.

If NetworkAwarenessCapable and this parameter are both true, the CPE MUST NOT go into a non CR-Aware Standby state.

The factory default value MUST be false.

If SelfTimerCapable and this parameter are both true, the CPE MUST NOT go into a standby state that prevents it from honoring Periodic Contacts.

The factory default value MUST be false.

If this parameter is true, the CPE MUST NOT go into a standby state that prevents it from honoring Scheduled Contacts. This means that, whenever the ACS has requested a Scheduled Contact:

*if SelfTimerCapable is true and the CPE chooses to go into Standby before the Scheduled Contact has been honored, it MUST use a Timer-Aware Standby;

*if SelfTimerCapable is false, the CPE MUST NOT go into Standby before the Scheduled Contact has been honored.

[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.

A pattern that describes the Parameter(s) to be included in the Inform’s ParameterList argument. Specifically, patterns with wildcards (an “*” character) in place of Instance Identifiers are allowed; any attempt to set the value otherwise MUST be rejected by the CPE.

If the pattern does not match any existing Parameters at the time that the CPE is creating the Inform RPC, then this InformParameter instance is not included in the Inform’s ParameterList argument.

Comma-separated list of strings. Each entry in this list represents an Event for which this Parameter MUST be included within the ParameterList argument of the Inform RPC.

All Inform Events (see [Section 3.7.1.5/TR-069]), except for “4 VALUE CHANGE”, are allowed as entries in this list. “4 VALUE CHANGE” is not allowed as that would violate requirements contained in [Section A.3.3.1/TR-069].

An empty string means all events except “4 VALUE CHANGE”.

An absolute time reference in UTC to determine when the CPE will initiate the Heartbeat event Inform method calls. Each Inform call MUST occur at this reference time plus or minus an integer multiple of the ReportingInterval.

InitiationTime is used only to set the phase of the Heartbeat event Informs. The actual value of InitiationTime can be arbitrarily far into the past or future.

For example, if ReportingInterval is 60 (one minute) and if InitiationTime is set to UTC midnight on some day (in the past, present, or future) then Heartbeat Informs will occur every minute at the next UTC midnight. These MUST begin on the very next midnight, even if InitiationTime refers to a day in the future.

The Unknown Time value defined in [Section 3.2/TR-106] indicates that no particular time reference is specified. The CPE MUST locally choose a random time reference.

If absolute time is not available to the CPE, its Heartbeat Inform behavior MUST be the same as if the InitiationTime parameter was set to the Unknown Time value.

{{template: non-existent VENDORCONFIGFILE-NAME}}

A string identifying the configuration file version currently used in the CPE.

If the CPE is able to obtain the version of the configuration file from the file itself, then the value of this parameter MUST be set to the obtained value.

Otherwise, the value of this parameter MUST be an empty string.

When true, this parameter indicates that this Device.DeviceInfo.VendorConfigFile.{i}. instance is to be used for backup and restoration purposes.

Note: The backup and restore operations may require the use of multiple Device.DeviceInfo.VendorConfigFile.{i}. instances. In this scenario the mechanism for detemining the order and combination of Device.DeviceInfo.VendorConfigFile.{i}. instances used for backup and restoration purposes is implementation specific.

A string identifying the version of the firmware image represented by this Device.DeviceInfo.FirmwareImage.{i}.. Whenever this firmware image is active (ie, the device has booted this firmware image), the value of the DeviceInfo.SoftwareVersion parameter MUST be the same as the value contained in this parameter.

To allow version comparisons, this element SHOULD be in the form of dot-delimited integers, where each successive integer represents a more minor category of variation. For example, 3.0.21 where the components mean: Major.Minor.Build.

The value of Version is an empty string if Status is anything other than Available, InstallationFailed, or ActivationFailed.

Specifies whether or not this particular firmware image can be used by the Agent. An Agent will only attempt to boot this particular firmware image if this parameter value is set to true.

This value MUST be set to true by the device whenever a new firmware image is installed.

This value cannot be set to false if the firmware image is active or is referenced by the BootFirmwareImage parameter.

Firmware image instances cannot be deleted, so a Controller MAY use this parameter to subsequently mark a particular firmware as being invalid, which will prevent the Agent from attempting to boot it.

Status of the firmware image, as determined by the Agent. Enumeration of:

• NoImage (This Firmware Image instance is empty. This value could happen on an Agent that supports multiple firmware images, but only has a single image installed)
• Active (This Firmware Image instance is the currently active image, added in 2.14)

• Validating (This Firmware Image instance has been downloaded, and is in the process of being validated)
• Available (This Firmware Image instance has been downloaded, validated, and installed, and is ready to be activated)
• DownloadFailed (The Agent has attempted to download this Firmware Image instance, but ultimately failed while retrieving it from the source URL)
• ValidationFailed (The Agent has attempted to validate a Firmware Image downloaded to this instance, but ultimately failed while validating it)
• InstallationFailed (The Agent has attempted to install a Firmware Image downloaded and validated to this instance, but ultimately failed while installing it)
• ActivationFailed (The Agent has attempted to active this Firmware Image instance, but ultimately failed while being activated)

If the Agent is unable to boot into this firmware image, when specified, the Agent can use this parameter to record some information as to why the boot failed.

If the Agent successfully boots into this firmware, the value of this parameter SHOULD be an empty string. When a new firmware image is installed into this object instance, this parameter MUST be cleared.

The length of this string is defined as implementation-specific by the Agent.

[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 URL MUST reference an XML file which describes the appropriate part of the Supported Data Model.

The referenced XML file MUST be compliant with the DT (Device Type) Schema that is described in [Annex B/TR-106], including any additional normative requirements referenced within the Schema.

The XML file referenced by this URL MUST NOT change while the CPE is running, and SHOULD NOT change across a CPE reboot. Note that UUID is a unique key, so the XML file referenced by this URL will never change.

The XML file MAY be located within the CPE. In this scenario the CPE MAY use the value of “localhost” as URL host portion, When the “localhost” value is used, the ACS has the responsibility to substitute the “localhost” value with the host portion of the connection request URL.

Behavior in the event of an invalid URL, failure to access the referenced XML file, or an invalid XML file, is implementation-dependent.

URN ([RFC3986]) that is the value of the spec attribute in the DM (data model) Instance that defines the Root Object or Service Object referenced by this table entry.

For example, if this table entry references a DT Instance that refers to the Device:2.13 Root Object, the value of this parameter would be urn:broadband-forum-org:tr-181-2-13-0. If the DT Instance instead referred to a vendor-specific Root Object, e.g. X_EXAMPLE_Device:1.0 (derived from Device:1.3), the value of this parameter would be something like urn:example-com:device-1-0-0.

Comma-separated list of strings. This parameter MUST list exactly the features that are defined using the top-level feature element in the DT Instance referenced by URL.

For example, if the DT instance specified the following:

• <feature name=“DNSServer”/>
• <feature name=“Router”/>
• <feature name=“X_MyDeviceFeature”/>

then the value of this parameter might be DNSServer,Router,X_MyDeviceFeature. The order in which the features are listed is not significant.

Status of Time support on the CPE. Enumeration of:

• Disabled
• Unsynchronized
• Synchronized
• Error_FailedToSynchronize
• Error (OPTIONAL)

The Unsynchronized value indicates that the CPE’s absolute time has not yet been set.

The Synchronized value indicates that the CPE has acquired accurate absolute time; its current time is accurate.

The Error_FailedToSynchronize value indicates that the CPE failed to acquire accurate absolute time; its current time is not accurate.

The Error value MAY be used by the CPE to indicate a locally defined error condition.

Note: This parameter is defined as ACT_LOGGING_DEPTH_REPORTING_R in Clause 7.5.3.4 of ITU-T Recommendation [G.997.1].

The value MUST be the Path Name of a row in the DeviceInfo.VendorLogFile. table. If the referenced object is deleted, the parameter value MUST be set to an empty string. This parameter identifies the log file of the the data gathering event trace buffer containing the event records that originated at the VTU-R.

This indicates the table entry that represents a Vendor Log File that contains the data gathering buffer at the VTU-R in the DeviceInfo.VendorLogFile table.

This data gathering buffer MAY be retrieved wia an upload RPC of the identified Vendor Log File.

Note: This parameter is defined as EVENT_TRACE_BUFFER_R in Clause 7.5.3.6 of ITU-T Recommendation [G.997.1] and Clause 11.5 of ITU-T Recommendation [G.993.2].

Enables or disables the channel.

This parameter is based on ifAdminStatus from [RFC2863].

The current operational state of the channel (see [Section 4.2.2/TR-181i2]). Enumeration of:

• Up
• Down
• Unknown
• Dormant
• NotPresent
• LowerLayerDown
• Error (OPTIONAL)

When Enable is false then Status SHOULD normally be Down (or NotPresent or Error if there is a fault condition on the interface).

When Enable is changed to true then Status SHOULD change to Up if and only if the interface is able to transmit and receive network traffic; it SHOULD change to Dormant if and only if the interface is operable but is waiting for external actions before it can transmit and receive network traffic (and subsequently change to Up if still operable when the expected actions have completed); it SHOULD change to LowerLayerDown if and only if the interface is prevented from entering the Up state because one or more of the interfaces beneath it is down; it SHOULD remain in the Error state if there is an error or other fault condition detected on the interface; it SHOULD remain in the NotPresent state if the interface has missing (typically hardware) components; it SHOULD change to Unknown if the state of the interface can not be determined for some reason.

This parameter is based on ifOperStatus from [RFC2863].

[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.
