Section 9, of WTSA (Montreal, 2000)
Geneva, 2 February 2001
Dear Sir/Madam,
1
At the request of the Chairman of Study Group 7, Data networks and open system
communications, I have the honour to inform you that this Study Group, which will meet from
29 January to 2 February 2001, intends to apply the procedure described in Resolution 1, Section 9,
of WTSA (Montreal, 2000) for the approval of 16 revised Recommendations and new
Recommendations.

Any ITU Member or Sector Member or Associate aware of a patent held by itself or others
which may fully or partly cover elements of the draft Recommendations proposed for approval is
requested to disclose such information to TSB, in accordance with TSB patent policy (see
Appendix III to WTSA Resolution 1).
Available patent information can be accessed on-line via the ITU-T Website.

Having regard to the provisions of Resolution 1, Section 9, I should be grateful if you
would inform me by 2400 hours UTC on 17 January 2001 whether your Administration assigns
authority to Study Group 7 that these draft revised or new Recommendations should be considered
for approval at the Study Group meeting.
Should any Member States be of the opinion that consideration for approval should not
proceed, they should advise their reasons for disapproving and indicate the possible changes that
would facilitate further consideration and approval of the draft revised or new Recommendations.
5
If 70% or more of the replies from Member States support consideration for approval of
these draft revised or new Recommendations at the Study Group meeting, one Plenary session will
be devoted on 2 February 2001 to apply the approval procedure.
I accordingly invite your Administration to send a representative to the meeting. The
Administrations of Member States of the Union are invited to supply the name of the head of
their delegation. If your Administration wishes to be represented at the meeting by a recognized
operating agency, a scientific or industrial organization or another entity dealing with
telecommunication matters, the Director should be duly informed, in accordance with Article 19,
No. 239, of the ITU Convention.
6
The agenda, registration form and all relevant information concerning the Study Group 7
meeting will be available from Collective-letter 1/7.

After the meeting, the Director of TSB will notify, in a circular, the decision taken on these
Recommendations. This information will also be published in the ITU Operational Bulletin.
Yours faithfully,
H. Zhao

DRAFT NEW RECOMMENDATION X.86 (X.eos): “ETHERNET OVER LAPS”;
see COM 7-20 (Q.7/7)
Summary
Transferring Ethernet over LAPS is a simple and cheap technique to connect LANs within a private
and public network. This Recommendation specifies a protocol suite structure of Ethernet (defined
by IEEE WG 802.3) over LAPS for the purpose of providing the future protocol compatibility
among peer systems, and applies to Synchronous Digital Hierarchy (ITU-T Recommendation
G.707). The capabilities of supporting the LAPS protocol procedure at high speed, and IEEE 802.3
frame directly mapping to LAPS are mainly included. This Recommendation will be used to data
network and open system communications related to private and public networks.

DRAFT REVISED RECOMMENDATION X.530: “INFORMATION
TECHNOLOGY - OPEN SYSTEMS INTERCONNECTION - THE DIRECTORY:
USE OF SYSTEMS MANAGEMENT FOR ADMINISTRATION OF THE
DIRECTORY”; see COM 7-29 (Q.12/7)
Summary
The Directory may support open systems applications such as message handling systems, File
Transfer, Access and Management (FTAM) systems, and transaction processing systems.
Therefore, the Directory system may be manageable from an integrated system management
platform.
This purpose of Directory management is to assure that needed, accurate Directory information is
available to users as scheduled with the expected response time, integrity, security and level of
consistency. Furthermore, systems management may be accomplished with the minimum burden on
processing time and memory on platforms and the communications system.
This Recommendation | International Standard describes the requirements for Directory
management, and analyses these requirements to identify those that may be realised by OSI
Systems Management services (and protocols), those that are realised by Directory services (and
protocols), and those that are realised by local means.
