Abstract: In a data processing system that includes a plurality of system components coupled to a time division multiplexed data bus, a computer-implemented method for assigning a plurality of transmission opportunities within a transmission cycle among the plurality of system components. A system component is selected, and the number of transmission opportunities within the transmission cycle required by the system component is determined. Transmission opportunities are assigned to the system component such that each transmission opportunity is evenly spaced from a next transmission opportunity within an acceptable margin of error. The process is repeated for each system component.

Abstract: A data processing system. The data processing system includes a time division multiplexed (TDM) bus and a plurality of system components coupled to the TDM data bus. A memory stores a table of allocation entries. Each allocation entry indicates which one of the plurality of system components, if any, to be allocated a corresponding bandwidth unit (BU), wherein each BU comprises a contiguous block of TDM timeslots. An allocation control circuit is coupled to the system components and the memory for accessing the allocation table and allocating BUs to the system components on a BU-by-BU basis so that the allocation control circuit operates at a slower speed than the TDM data bus.

Abstract: A packet communications network and apparatus for communicating information in voice and data packets transmits and receives voice and data in accordance with standardized frames of a standardized communications format such as a standard DS-1 type trunk. An apparatus is coupled to multiplex standardized channels into a single channel wherein voice or data signals are packetized into independently addressable packets synchronized on, for example, the DS-1 frame. The network includes voice and packet data concentration apparatus operable in a multiple node trunk environment to concentrate signals into independently addressable synchronously switchable packets, thereby to provide an efficient (high density capacity) interface between trunk terminations. Up to four times as much information can be transferred between nodes with the ability to switch between nodes as compared to conventional TDM and PCM communication without compression without the ability to switch between nodes.
