ABSTRACT:
An operating system is provided for an analog switching machine having switch fabric formed by multiple line and trunk link networks having interconnected switch stages with each switch stage having multiple grid connections and makes post-connection continuity checks. Error messages are generated for connection faults and sent to a monitor and analyzer computer. The error messages are automatically processed to identify the root causes of connection faults, i.e. to detect open and stuck crosspoints, faulty interstage links and faulty pulse path devices. The analyzer computer further generates command signals that provide for removal of faulty crosspoints and other failed elements from analog switching machine operation.
