Abstract

PURPOSE:To allow a called subscriber to identify whether an incoming call is a call transferred from another station or a usual incoming call. CONSTITUTION:When a call reaching a called subscriber 2 accommodated in an exchange station A3 with an incoming transfer service given thereto is transferred to another exchange station B5 to be designated, the exchange station A3 starts a common line signal control circuit 8. The common line signal control circuit 8 adds incoming call transfer information representing a transfer call from another station to an address signal with additional information of a N0.7 common line signal system and outputs the result to a signal link 4. A common line signal control circuit 9 identifies incoming call transfer information from the received address signal, the exchange station B5 receives the information to send a call tone different from a usual call to a transfer destination subscriber 6.
