Abstract
A single CCIS central processing unit is employed to receive and transmit CCIS data from a central switching office to other CCIS offices via modems, or digital trunk units and T1 spans. This apparatus facilitates orderly and timely data exchange between a CCIS central processing unit and a plurality of data terminal equipment. Every 10 milliseconds the CCIS CPU scans all the data terminal equipment. However, particular data transmissions require interaction at a more rapid rate. The present invention provides for a high priority data transmission from the terminal equipment to the central processing unit intermingled with regular priority messages.
