ABSTRACT:
An announcement apparatus for a switching system, comprising a host processor for controlling the output of announcement voices with respect to the total voice service channels, a DPRAM for storing voice output address data therein, a CPU responsive to an interrupt signal, for storing the voice output address data into the DPRAM and outputting voice output state data, a common memory for transferring voice output command data from the host processor to the CPU and transferring the voice output state data from the CPU to the host processor, a fixed voice memory for storing fixed announcement voice data therein, an edited voice memory for storing edited announcement voice data therein, and a memory controlling/voice processing circuit for outputting the interrupt signal to the CPU, reading the voice output address data from the DPRAM, outputting the read voice output address data to the fixed voice memory or the edited voice memory, converting parallel announcement voice data from the fixed voice memory or the edited voice memory into serial data and transferring the converted serial data to a time switch of the switching system through a sub-highway.
