  • Circuit for reliable data transfer between two central processing units
    Patent number: 4502114
    Abstract: This circuit provides a minimally sized data transfer buffer interface between two central processing units for transferring data blocks of variable size. The circuit provides an indication to one CPU that the other CPU has received all the data words transmitted.

  • Circuitry for recovery of data from certain bit positions of a T1 span
    Patent number: 4467469
    Abstract: This circuit provides for retrieving common control interoffice signaling (CCIS) data from a PCM voice data stream of a T1 span. T1 spans interconnect switching offices. Unused data bits in these T1 spans are encoded with CCIS data and transmitted between the switching systems where the CCIS data is recovered.

  • Apparatus for CCIS data transfer between a CPU and a plurality of data terminal equipment
    Patent number: 4466062
    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.

  • Remote data link switching arrangement
    Patent number: 4464748
    Abstract: An automated switching office arrangement for switching data link transmission from analog to digital data or vice versa is disclosed. Any or all of a number of data links may be automatically switched between the digital and the analog transmission modes. This automated switching may be accomplished locally within the switching office or from a remote location.
