    摘要: A signal transmission system comprises a transmitter, a receiver and a transmission link in which the signal to be transmitted is pulse code modulated. The transmission link comprises a plurality of channels (0--7), one for each bit of the pulse code modulated signal. The quality of each channel is monitored and the bits of the pulse code modulated signal are applied to the channels such that the most significant bits of the pulse code modulated signal are allocated to the channels having the lowest level of interfering signal.

    摘要: Incoming data which is required to be passed to a desired storage location under the control of a processor is received by a store prior to being passed to a serial communications controller. The store is preferably a FIFO store and stores the data at an incoming data rate determined by the incoming transmission line data rate and feeds the data to the serial communications controller at a higher data rate under the control of a clock generator which is energized by control circuitry only when the serial communications controller indicates that it is able to accept the data. The processor can therefore control the serial communications controller to cease to process incoming data, which data is then stored until the processor can spare the time to recommence processing the incoming data.

    摘要: Computer aided design method and apparatus which automatically generate pin-to-pin interconnection lists between respective discrete electrical component circuits. Input devices provide for entering a list of components used, a description of those components and the circuit interconnection description. The memory store contains a library of standard component descriptions. A processing unit process the entered circuit description and selected component descriptions from storage to produce an interconnection list in the form of an individual component pin to individual component pin connection.

    摘要: A method for processing token identifiers for Layer 3 (L3) control channels when encapsulated in a tunneling protocol. Rather than encapsulating an L3 control channel with a secondary L3 (or Layer 4 ‘L4 ’) header, a generic (non-Layer 3 header) identifier, or token identifier, is used to encapsulate the control channel. For example, the token identifier may be a simple bit pattern that does not require a complex, confusing or redundant IP/UDP routing table lookup. Instead, the token identifier simply alerts the forwarding entity that local processing of the packet's data is required (e.g., that the packet contains control channel data).
