PURPOSE:To connect an integrated mail equipment to subscriber's terminals through a single No. by providing a circuit terminal equipment with a attribute information holding function and transmitting the attribute information to the integrated mail equipment. CONSTITUTION:Holding circuits 22, 42, 62 store and hold the attribute information and are formed by rewritable memories or the like. Registering circuits 23, 43, 63 transfer the attribute information inputted from attribute input circuits 24, 44, 64 to the holding circuits 22, 42, 62 to hold the information. The integrated mail equipment 8 is enabled to transmit/receive plural kinds of communication media to/from the subscriber's terminal and has a connection port to a circuit exchange 1 in common with respective communication media and a single exchange No. is assigned to the connection port.
