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