The system generates the T-copy of the underlying transaction envelope (Речь идет о денежных переводах)

Вопрос в том, что такое T-copy ?

Заранее благодарна за помощь!

в Инете нашла следующее:

– Y-Copy mode allows a copy destination to receive a copy of all or part of a FIN message and to authorise or prevent its delivery to the addressee. This is typically the case for the clearing, netting and settlement of payments, securities and other financial transactions. 

– T-Copy mode forwards copies to a copy destination while the original message is immediately forwarded to the receiver, without waiting for authorisation. This mechanism provides an ideal solution for risk, cash or collateral management, monitoring and reporting.

Вопрос в том как расшифровать это - Y-copy and T-copy.
