  • Method and apparatus for transmitting message cells via an ATM communication equipment
    Patent number: 5506842
    Abstract: An interface (SSE) is provided for transmission of message cells appearing on an offering trunk (ZL) with a specific transmission bit rate and belonging to different virtual connections or virtual paths via inputs of an ATM communication equipment (ATM-K) designed for a lower transmission bit rate. This interface includes a plurality of processors (MBHE, SBHE1, . . . , SBHE3) connected to the offering trunk which have their output sides respectively connected to at least one of the inputs. Under the control of one of the processors as a master processor (MBHE), the message cells are cyclically distributed onto all processors and, subsequently, are forwarded by these processors to the ATM communication equipment, upon attachment of a sequence number that is valid at the moment for the respective virtual connection or respective virtual path.
