Interim Procedures for the delegation of E.164
Shared Country Codes for Networks and Groups of Countries
These procedures have been approved on 15 May 2008 by ITU-T Study Group 2
1 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 or an assignee of a Identification Code (IC) from a
shared E.164 Country Code for Networks or Group Identification
Code (GIC) from a shared E.164 Country Code for Group of Countries
before final approval of the future Recommendation. The
procedures to be described in the finally approved version of the
future Recommendation will supersede these interim
procedures. These procedures shall not prejudice the future
Recommendation.
The following agreements will apply 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-N/GoC, which will then supersede these interim procedures.
- The interim procedures can be modified at any time and will be reviewed no
later than the scheduled November meeting of SG2 in 2003.
These interim procedures cover only assigned CC + ICs and CC +
GICs within the respective shared E.164 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 not covered in this or any other interim procedure.
2 Interim Procedures
These interim procedures are consistent with the agreed SG2
statement that the CC + IC assignee or CC + GIC administrator
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). In the
case of CC + ICs, it is a national matter whether requests for
codes require national Administration review or approval.
2.1 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 country code is a
currently-assigned resource
- All number assignees (IC or GIC code holders) within
the requested CC must endorse the request.
In the alternative, when a request representing the entire
code is received and endorsed by two or more code holders,
but not all of the code holders, within the shared country
code, this request shall also be accepted provided that no
code holder within the shared country code objects within 60
days and that there is a formal agreement between the TSB
and the Tier 1 Registry that only those portions (i.e., ICs
or GICs) of the code for which the requesting code holders
are responsible will be delegated.
Furthermore, when only a single code holder within a shared
country code requests that its IC or GIC be delegated, this
request may also be accepted if the request corresponds to
that IC or GIC for which the code holder 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 IC
of GIC for that specific code holder will be delegated under
a separate arrangement between the code holder 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.
2.2 Assignee Position Known
If the conditions of 2.1 are met, and if the concerned assignee
has notified the TSB of its position regarding delegation for
ENUM of its CC + IC or GIC, then the TSB will immediately make
that position known to RIPE NCC.
That is, TSB will inform RIPE NCC that the concerned assignee
either approves or objects to the delegation. If the
assignee 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 assignee has notified the TSB that it approves
that particular Tier 1 entity.
2.3 Assignee Position Not Known
If the conditions of 2.1 are met, but the concerned assignee has
not previously notified the TSB of its position regarding
delegation for ENUM of its CC + IC or GIC, 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 assignee.
- Within 60 days, notify the concerned assignee of the
request and of the TSB objection sent to RIPE NCC, and
request the assignee to advise the TSB if the objection
should be rescinded and an approval sent to RIPE NCC.
- If an approval is received from the assignee, notify
RIPE NCC of that approval.
That is, the delegation will not take place until the concerned
assignee has notified the TSB that it approves the delegation.
2.4 Change in Position
If an assignee 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 + IC or GIC.
- 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 +
IC or GIC.
- There is a change in the party to which the CC+ IC or
CC + GIC 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. In
the case of Groups of Countries, any change would need to be
certified by the administrator of the CC + GIC.
That is, an assignee may at any time stop, enable, or change
ENUM delegations.
2.5 Communication Methods
- Communications between the TSB and assignee will be
between the Director of the TSB and the official contact
nominated by the assignee and on file with the ITU.
Assignees 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.
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.
