via a secure API gateway using a system known as Secure Data Transfer (SDT), developed under contract to Her Majesty's Courts and Tribunals Service in 2013 by a third party supplier. Previously files could be submitted on floppy disk or magnetic tape. For this reason long-standing users of the CCBC may still refer to the data file as the "tape". In 2012 a secure email transfer system was implemented as an interim measure until the new SDT system was completed. Once this was done the secure email transfer option was removed. CCBC users may poll the SDT API to request updates on the status of their cases. Depending on the nature of the original request some information (i.e. basic validation) may be available within a few minutes of data having been uploaded, whilst other information may not be available until the request has been fully processed by the Court Service internal systems - this can take 24 hours or longer. As well as issuing claim forms, the CCBC also handles requests for judgments and warrants of execution in the same manner. Defendant responses Claim forms issued by the CCBC are served upon the defendant(s) in the same manner as other courts. However, the response pack also includes a password to allow the defendant to file their response via a website. Where the defendant contests some, or all, of the claim, the claimant is required (if they wish to continue) to request the case be transferred out of the CCBC. Limitations Rule 7 allows for limits to be placed on the types of claim that may be issued via the CCBC. These are currently: The claim must be for issue in the County Court and not the High Court; The claim form cannot refer to separate particulars of claim; The claim must be for a specified sum of money less than £100,000 sterling, and expressed in sterling; The claim cannot be against more than two Defendants; Where there are two defendants the claim against each of them must be for the same amount; The defendants must not be a child or patient (within the meaning of Rule 21 of the Civil Procedure Rules) or a legally assisted person (within the meaning of the Legal Aid Act 1988); The defendant cannot be the Crown; The defendants' address for service must be within England or Wales. In addition the CCBC cannot be used
