DISTRIBUTING SYSTEM OF NIGHT INCOMING CALL WITH AUTOMATIC EXCHANGE

PURPOSE:To distribute properly a night incoming call by setting freely a night direct extension to any extension without fixing said direct extension and at the same time ensuring various types of services offered by an automatic exchange when an incoming call is received. CONSTITUTION:A night incoming call given through a trunk line 15 is detected by a signal control processor (SCP) 10, and the incoming information is sent to a connection control processor (CNP) 11 via a common bus 12 provided among processors. The CNP11 receives the incoming information from the line 15 and delivers a read indication to the SCP10 via the bus 12 for the number information of a night direct extension. The number information read out of a temporary storing memory 19 for the registration of the night direct extension is sent to the CNP11 for identification via the SCP10. In this case, a channel switch 13 is controlled via a channel switch control bus 16 to connect the night direct extension to the line 15 if the incoming is possible for the corresponding extension.
