PURPOSE:To increase a time division type switchboard and to shorten a connecting time by providing an analog-digital converter on a time division type switchboard, and connecting it to a delivery and an entry of a junctor part of a space division type switchboard. CONSTITUTION:When a subscriber 4-1 dials a called subscriber's number of a subscriber 4-2, a channel which reaches a line link network 1-1, a line interface 1-2 and a connecting point 1-2a through a channel control device 1-7 is formed by a number translation of a call processor 1-8. Also, the interface 1-2 sends the cutting-off supervisory information of the subscriber 4-1 to the processor 1-8 through a scanner 1-6 and the device 1-7. On the other hand, the information number translated by the processor 1-8 is transferred to a call processor 2-200, too, through a maintenance operating processor 3-1, converted as the call bus information of a time division type switchboard 2, and a channel bus which reaches the subscriber 4-2 through a channel control device 100 is formed. |
