Abstract

PURPOSE:To ensure an assured identification for the presence or absence of the error in the received information, by adding the answer code in place of the transmission code of the received information with transmission code and then sending the answer code with a view of confirmation via the communication unit at the reception side. CONSTITUTION:The unit CE4 at the reception side adds and transmits the answer code R (e.g. ''1'') in place of the transmission code C (e.g. ''0'') of the received information CD1 with transmission code with a view of confirming that it has received the information D1. The unit CE3 at the transmission side collates the answer code sent back from the unit CE4 to the information CD1. Thus an assured transmission with no error can be confirmed for the information D1 to the unit CE4.
