Direct Access to the IDC Databases
"As an initial service and before the Sixteenth Session of WGB, the so-calledArchive Database will be made available to the States Signatories within a secureenvironment. Initially, the synchronization will be done every 24 hours with amaximum downtime of 30 minutes per day" CTBT/PC-15/I/Annex II page 11
As a result of an evaluation workshop in May 2002:
"Working Group B recommends that the PrepCom task the PTS to provide theNDCs with timely and direct access to the information contained in the operationaldatabase, the archive database and the corresponding parameter files."CTBT/WGB-18/lpage7.

Who are the IDC Users?
CTBTOPREPARATORY COMMISSION
Where do the authorized IDC Users come from?• The provisional National Authority and the National Data Centre (NDC) of
State Signatories. (These may be the same place or located in separateestablishments).
• NDCs can be subdivided, with each subdivision being located in a separateestablishment and dealing with one or more of the IMS technologies.
Currently, guidelines and draft model agreement for data and product distributionto Disaster Alert and Scientific Organizations, has not been decided upon by WGB.• Two exceptions: ISC (limited to 2000 and 2001 REB) and WMO (limited to
meteorological observation data).

WGB/Preparatory Commission Decisions
The Eleventh Session of Working Group B (WGB-11) in February 2000:
• As part of the initial testing, a single secure signatory account has beenestablished for use by the provisional national authority, or other designatedorganization, of each State Signatory... Each State Signatory will ensure that theindividuals authorized for access to its secure signatoiy account are staffmembers of their provisional national authority or designated organization.
• WGB-12 in May 2000 defined three classes of Users. During the continuedtesting period ... all IMS data and IDC products obtained from the IDC fortesting shall be used only within the designated establishments.
• WGB-13 in September 2000 introduced technical assistants to resolve technicalproblems related to distribution.
• WGB-16 in September 2001 reviewed the experience with the testing ofprocedures for distribution of data and products to States Signatories.

WGB/Preparatory Commission Decisions (continued)
• WGB-16 noted that these initial procedures have worked well.
• WGB-16 agreed that this policy on distribution will continue until the beginningof full scale testing (Phase 5b of the IDC Commissioning Plan), and will bewithout prejudice to future decisions on policies governing distribution of IMSdata and IDC products.

Different Classes of IDC Users
Three classes of users, nominated by the principal point of contact and authorizedby the State Signatory, can access IMS data and IDC products through the singlesecure signatory account established for each State Signatory:
• Principal Users (Limit - 18 from up to 6 establishments): Access to all IMSdata and IDC products through IDC secure web site or email (AutoDRM). Canrequest data subscriptions, establish national event screens and request experttechnical assistance.
• Regular Users (Limit - normally up to about 10): Access restricted to IDCsecure web site.
• Station Operators and Station Maintenance Personnel (no limit defined):Access restricted to station status information and waveform data from theirstations which are already stored at the IDC.

CTBTOPREPARATORY COMMISSION
Four Steps to become a User of the IDC Access Methodsto Data and Products
1. Become an Authorized User. Only authorized users can access the IDCproducts and services.
2. The IDC has to be informed about the appointment and given sufficientinformation about the users to be able to identify them.
- A completed Secure Signatory Account Registration Form allowsthe PTS to activate a single Secure Signatory Account for each StateSignatory. Send the completed form through your Permanent Mission.
3. Receive information from the IDC regarding user accounts and passwords.
4. Establish connection to the IDC. Communication links between the NDCsand IDC are provided by the Internet or the GCI (managed by the IDC).

The National Data Centre (NDC)Definition and Organizational Structure
The National Data Centre could be defined as:• The group of persons at, or under the guidance of, the National Authority which
are technical experts in the monitoring technologies.
Organizational Structure:• A separate Institute/Agency or a part of the National Authority.
• The two main functions of the NDC could be given to two or more institutes.The NDC can also be subdivided with each subdivision dealing with one ormore of the monitoring technologies.

The National Data Centre (NDC)Mam Functions
NDC Main Function• Receive and analyse the IMS data and the IDC products and verify the nature of
the events. Provide technical advise to the National Authority.
NDC Optional Function• Provide data obtained from national stations that are part of the IMS. This can
involve to operate and maintain the IMS stations, and to act as a communicationnode for data from these stations. This will be based on an agreement orarrangement with the PTS.(one slide)

NDCs National Role
• Use IMS data and IDC products as needed to assist the verification efforts
• Advise the National Authority by:- Verifying the nature of the events and the compliance with the Treaty- Reviewing proposed technical changes to the verification system- Providing technical advice to the representatives in the Executive Council
• Provide scientific expertise to the technical subsidiaiy organs (ScientificAdvisory Board, Working groups of scientific experts)
• Act as an interface to national scientific organizations and civil applications ofthe verification technologies
• Responsible for the proper use of IMS data and IDC products (confidentialitypolicy)

The NDCs Role with the Verification Elements
• Provide supplementary data to the IDC on voluntary basis (confidence-buildingmeasures).
• Participate as appropriate in the consultation and clarification process.
• Participate in calibration projects. Through providing additional region-specific orsite-specific knowledge.
• The NDCs can access and explore the special data management activity.- CBM- OSI- C&C- CNF

NDCs Voluntary Role
• Feedback to the IDC
• Evaluation and assist the products
• Participate in the enhancement process of the verification system performance
Means:
- provide "ground truth,, information and acting positively in the CBM- provide statistics gathered from results obtained from local and regional dense
networks

Role of NDCs - Building its Capability
Determine the hardware and software needed to receive, display and process IMSdata and IDC products. (With the help of the IDC as needed.)
Develop the capability to receive, process and analyse IMS data. (With the help of the IDCas needed.)
NDCs may like to have their software for computing new signals or event parametersinstalled at the IDC.
Develop, as needed, national screening criteria.
Formulate their requirements for selection and screening of data and products. (With thehelp of the IDC as needed.)

Summary
An introduction was given to
Methods to access data and productsEstablishments, principal and regular usersTechnical assistance and trainingThe role of NDCs
Significant progress over past five years to establish system.
State Signatories profit from the services provided by the IDC.
The interaction between NDCs and the IDC is considered as vital.
The system will improve with expansion and experience.
