ExtraNet

BBS is accessed via the Deutsche Bundesbank's ExtraNet. To this end, the BBS is integrated into the ExtraNet, the Deutsche Bundesbank's e-business platform.

ExtraNet provides a secure basic infrastructure for access to the Deutsche Bundesbank's web-based applications and for the confidential transmission of data between the customer and ExtraNet. Encrypted data transmission is used for this purpose. This is based on Secure Socket Layer technology in its current encryption version and on the secure https internet protocol.

Secure access is ensured by centralised authorisation via user ID and password for all applications in ExtraNet.

Essential rules for using ExtraNet are contained in the ExtraNet General Terms and Conditions as well as the BBS special rules issued pertaining to this, which have to be accepted by all BBS customers with the set-up of users.

Further information on the operation of ExtraNet may be found in the ExtraNet documentation. The passages which are of particular relevance to the members of the Bund Issues Auction Group as BBS customers are contained in

• Part III: Basic services; chapter 3: User management

This explains in detail how to

• set up a user profile
• change user data
• block a user
• unblock a user
• reset a password
• delete a user.

At this point, we draw your attention to the fact that changing the name and first name of the user, thereby handing on the user ID, which is technically feasible in ExtraNet and described in the documentation, is expressly forbidden by the Special terms and conditions of the Deutsche Bundesbank for auctions of German Federal securities through the Bund Bidding System (BBS). The same applies to the use of the function user, for which ExtraNet has the technology.
