      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
      {{bibref|TR-069|3.6.1}} and described in {{bibref|TR-069|Appendix II}},
      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.
    </description>
  </dataType>

  <dataType name="IPAddress">
    <description>
      IP address, i.e. IPv4 address (or IPv4 subnet mask) or IPv6 address.

      All IPv4 addresses and subnet masks MUST be represented as strings in
      IPv4 dotted-decimal notation. Here are some examples of valid IPv4
      address textual representations:

      * 216.52.29.100

      * 192.168.1.254

      All IPv6 addresses MUST be represented using any of the 3 standard
      textual representations defined in {{bibref|RFC4291}} Sections 2.2.1,
      2.2.2 and 2.2.3. Both lower-case and upper-case letters can be used, but
      use of lower-case letters is RECOMMENDED. Here are some examples of valid
      IPv6 address textual representations:

      * 1080:0:0:800:ba98:3210:11aa:12dd

      * 1080::800:ba98:3210:11aa:12dd

      * 0:0:0:0:0:0:13.1.68.3

      IPv6 addresses MUST NOT include zone identifiers. Zone identifiers are
      discussed in {{bibref|RFC4007|Section 6}}.

      Unspecified or inapplicable addresses (or IPv4 subnet masks) MUST be
      represented as empty strings unless otherwise specified by the parameter
      definition.

      <parameter name="TestState" access="readWrite">
        <description>
          Indicates the current test state. {{enum}} Value MAY be set to
          {{enum|Requested}} to initiate a diagnostic test. When writing, the
          only allowed value is {{enum|Requested}}. 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 value
          {{enum|Requested}}. When requested, the CPE SHOULD wait until after
          completion of the communication session with the ACS before starting
          the test. When the test 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.
