HIGH-SPEED QUEUE SEQUENCER FOR A BURST-SWITCHING COMMUNICATIONS SYSTEM ABSTRACT: This invention provides a high-speed queue sequencer which may be employed as a component of a link switch or hub switch in a burst-switching communications system. When so employed, transmission speeds for integrated voice and data services over communications links between switches may be equivalent to the T1 rate or higher. A burst is a plurality of bytes which represents, for example, a block of data or a spurt of voice energy sensed by silence/voice detectors located at voice ports. In a preferred embodiment, the architecture of the queue sequencer includes a data/address bus, control including a stored program in a 64-bit wide PROM, a random-access memory for queue memory which stores administrative information pertaining to bursts passing through the switch, enque means for adding a burst to the list of bursts awaiting assignment to an output channel, and deque means for assigning the highest-priority burst on this list to an output channel and removing the burst from the list, first-in first-out memory for storing requests from switching processors and providing these requests to the control of the queue sequencer within priority class in the same time order as received, and input and output interfaces for coupling with the switching processors. A switching processor is a companion high-speed processor employed as one or more components in a link switch and hub switch. Most components of the queue sequencer operate substantially in parallel with and independently of the control, which is a contributing factor to the speed advantage realized by the queue sequencer. The queue sequencer performs queue administration for all switching processors of a link or hub switch.
