ENUM administration ad interim
These procedures have been approved on 15 May 2008 by ITU-T Study Group 2
1 Background
There is considerable interest in implementing ENUM in some Member
States so that it would be appropriate to provide interim procedures to
enable such activities to take place.
In response to this interest, the Internet Architecture Board (IAB)
issued instructions to RIPE-NCC regarding how to proceed with any requests
received by RIPE-NCC. Those instructions can be found at http://www.ripe.net/enum/instructions.html.
Additional information on ENUM can be found at http://www.ripe.net/enum/.
It should be noted that the cited instructions are fully consistent with
the statement:
Member States will have the right to choose whether to participate
in the common designated ENUM domain, or not to participate in it, at
their discretion.
Consistency with the above statement is achieved by RIPE-NCC’s
referring any requests for delegations of domain names corresponding to
E.164 country codes to the Telecommunications Standardization Bureau (TSB)
for approval.
It is important that the TSB process any such requests in a transparent
and consistent way, and therefore these procedures have been created. In
the long-term, it is envisaged that the TSB processes and procedures will
be specified in a future Recommendation(s).
2 Scope
The purpose of this document is to set out the interim procedures that
will be used by the TSB, should the TSB receive a request from RIPE-NCC
before final approval of the future Recommendation(s). The procedures to
be described in the finally approved version of the future
Recommendation(s) will supersede these interim procedures. These
procedures shall not prejudice the future Recommendation(s).
The following agreements were made relative to the interim procedures:
- The interim procedures will remain in effect until the approval of a future Draft
Recommendation(s), currently Draft Recommendation E.A-ENUM, which will
then supersede these interim procedures.
- The interim procedures can be modified at any time and will be reviewed
no later than the next scheduled meeting of SG2 in 2005.
These interim procedures cover only assigned geographic country codes.
Unless further guidance is received to the contrary from Study Group 2,
the TSB will send an objection to RIPE NCC with respect to any requests
for delegations of any other types of country codes.
3 Interim Procedures
These interim procedures are consistent with the agreed SG2 statement
that Member States will have the right to choose whether to participate in
the common designated ENUM domain, or not to participate in it, at their
discretion, and with the procedures currently under development as
specified in the future Recommendation(s).
3.1 Formal Validity of CC
When the TSB receives a request from RIPE NCC, it will first verify
that the country code (CC) mentioned in the request meets the formal
conditions for delegation for ENUM, namely:
- That the code is a currently-assigned country code, and
- For country codes shared by two or more Member States within an
integrated numbering plan or in another framework, all Member States must endorse
the request.
In the alternative, when a request representing the entire code is
received and endorsed by two or more Member States, but not all of the
Member States, within an integrated numbering plan, this request shall
also be accepted provided that no Member State within the integrated
numbering plan objects within 60 days and that there is a formal
agreement between the TSB and the Tier 1 Registry that only those
portions of the code for which the requesting Member States are
responsible will be delegated.
Furthermore, when only a single Member State within an integrated
numbering plan or in another framework requests that its numbering
resources be delegated, this request may also be accepted if the
request corresponds to that portion of the code for which the Member
State has administrative responsibilities and the country code is
delegated to the Tier 0 Registry and there is a formal agreement
between the Tier 0 Registry and the TSB to the effect that only the
numbering resources for that specific country will be delegated under
a separate arrangement between the specific country and the Tier 0
Registry.
If these conditions are not met, the TSB will notify RIPE NCC that it
objects to the delegation. As a consequence, the delegation will not take
place.
3.2 National Position Known
If the conditions of 3.1 are met, and if the concerned Member State has
notified the TSB of its position regarding delegation for ENUM of its CC,
then the TSB will immediately make that position known to RIPE NCC.
That is, TSB will inform RIPE NCC that the concerned Member State
either approves or objects to the delegation. If the Administration
objects, the delegation will not take place.
Since the request from RIPE NCC will designate a specific ENUM Tier 1
Registry, the TSB will only be able to approve the request if the Member
State has notified the TSB that it approves that particular Tier 1 entity.
3.3 National Position Not Known
If the conditions of 3.1 are met, but the concerned Member State has
not previously notified the TSB of its position regarding delegation for
ENUM of its CC, then the TSB will proceed as follows:
Within 60 days, notify RIPE NCC that it objects to the
delegation, because it has not received approval from the concerned
Member State.
- Within 60 days, notify the concerned Member State of the request
and of the TSB objection sent to RIPE NCC, and request the Member
State to advise the TSB if the objection should be rescinded and an
approval sent to RIPE NCC.
- If an approval is received from the Member State, notify RIPE
NCC of that approval.
That is, the delegation will not take place until the concerned Member
State has notified the TSB that it approves the delegation.
3.4 Change in National Position
If a Member State notifies the TSB of a change in its position, the TSB
will communicate that change to RIPE NCC, who will implement the change.
The changes can be:
- A previously granted approval becomes an objection. In this
case, the delegation will be removed and ENUM will no longer be
available for the concerned CC.
- A previously stated opposition, or lack of approval, becomes an
approval. In this case, the delegation will be granted and ENUM will
be available for the concerned CC.
- There is a change in the party to which the CC is delegated,
that is, a change in the ENUM Tier 1 Registry. In this case, the TSB
will notify RIPE NCC of that change and the change will be
implemented.
That is, a Member State may at any time stop, enable, or change ENUM
delegations.
3.5 Communication Methods
- Communications between the TSB and Member States will be between
the Director of the TSB and the official contact nominated by the
Administration of the concerned Member State and on file with the ITU.
Administrations of Member States are encouraged to notify the TSB
regarding who should be the official contact for ENUM matters. Such
notification shall be provided by the official contact described below.
In the absence of a specific notification for ENUM matters, the official
Administration point of contact listed in the ITU Directory will be
used. Communications will take place by physical letter or facsimile,
although E-Mail may be used in addition for clarification (but not for
formal decisions).
- To expedite the process, initial requests should be sent first to
the TSB. After approval is received, the requests can be sent to RIPE
NCC in conformance with the RIPE NCC Instructions.
- All approvals will be posted on the TSB Web site at http://www.itu.int/ITU-T/inr/index.html.
- Communications between the TSB and RIPE NCC will take place by
E-Mail. The TSB will designate a mail address for this purpose. The TSB
will keep an archive of all E-Mails sent and received.
Any approvals sent to RIPE NCC will be confirmed in writing by the
Director of the TSB.
- When notifying an approval to RIPE NCC, the formal approval letter
by the Director of the TSB will contain appropriate language with respect to the Member State’s
authority to revoke its approval and transform it into an objection.
