This part specifies those transactions. Clause 4 analyses the processes: session synchronisation, sign-on and sign-off, account contracting and pre-contracting initiated from either side, termination, currency code registration, amendment of the account information and of its status, information and balance enquiries from either side, and the bank-to-securities and securities-to-bank transfers in both directions.
