Abstract

PURPOSE:To reduce the processing time and to enable to save the memory, by providing the queuing registration memory with busy outgoing trunk every processor and providing the count memory for common queuing call numbers, in the stored program control electronic exchanger of multi-processor system. CONSTITUTION:When the extension 10 dials the registration code of the outgoint trunk busy queuing service with the outgoing trunk 16 under entirely busy condition, the processor 12 writes in the extension information in the outgoing trunk busy queuing service registration memory 14 and adds the number of queuing calls of every trunk group of the queuing call number count memory 24 by one. When the processor 18 detects the vacancy of the outgoing trunk 16, it transmits the control data and trunk group number to the data transfer controller 15. The processor 12 reads out it and the trunk connection control data is delivered to the data transfer controller 21 and the switch network controller 22 makes the control of the network.
