摘要： A processor (100) that executes applications (99) which require access to time slots of a time-division multiplexed (TDM) communications medium (110) uses spare processing capacity and/or spare hardware of the processor to interface to the TDM medium and to implement a time-slot interchange (TSI) function in a simple and low-cost manner. The processor has a control store (104) that stores a bit map of the time slots of the TDM medium. The bit map is either examined by the processor during each time slot to determine, or is used by external circuitry or spare internal circuitry of the processor to generate interrupts or DMA requests that indicate to the processor or to a host interface of the processor, which time slots to access. The processor has a read buffer (105) and a write buffer (106) for effecting data transfers between the TDM medium and the applications. The applications have random access to the buffers, thereby effecting a time-slot-interchange function.

摘要： An ATM cell constructor (100) limits transmission-delay variations between successive cells of traffic of individual narrowband and wideband channels in a multi-channel environment. Whenever an ATM AAL1 layer (112) of processing completes assembling (606) an ATM cell payload for a narrowband channel (611), it increments (612) a count that anticipates the number of ATM cells that will mature for transmission during the next cell construction period. For wideband channels, a function checks (1010) whether traffic from the number of narrowband channels that form the wideband channel will result in completion of assembly of that channel's cell payload during the next cell construction period; if so, the function increments (1012) the abovementioned count. The count is reset (302) at the beginning of each cell construction period. Upon receipt (700) of a command to add (start processing) a new channel, a TSI controller (132) compares (704) the count against a threshold that equals the total number of presently-active channels divided by the number of octets of traffic carried by each cell, plus one. If the threshold exceeds the count, the TSI controller sets up (706) a TSI (108) to start processing the new channel; otherwise the TSI controller delays (712-714) setting up the TSI to process the new channel until occurrence (902) of a cell construction period when the threshold exceeds the count. The net effect is to shift the delay variations from cells of active channels to the start-up of processing of new channels.

摘要： A port circuit (108) for a time-division multiplexed (TDM) switching system (100) is designed to effect sub-time-slot operation without external support, as well as to effect conventional time-slot operation. A clock-frequency multiplier, such as a frequency-multiplied phase-lock loop (PLL 202), and a multiplier-driven sub-time-slot operation circuit, such as a PLL-driven finite state machine (203), are incorporated into the port circuit. The clock-frequency multiplier and the sub-time-slot operation circuit generate all the additional control signals that are necessary to define sub-time slots and to effect multiple information transfers in a single time slot. The port circuit engages in conventional time-slot transfers with conventional port circuits, whereby it is compatible therewith, and engages in sub-time-slot transfers with other sub-time-slot enabled port circuits, whereby it increases the transfer throughput of the TDM switching fabric. The sub-time-slot operation is selectively enabled and disabled on a per-time-slot basis.

摘要： An ATM cell constructor (100) of an ATM transmitter assembles a stream of frames of constant bit-rate traffic received on a listen TDM bus (102) into cell payloads using ATM adaptation layer 1 (AAL1). Once every eight cells, the AAL1 structured data transfer (SDT) cell constructor layer (112) introduces a one-octet SDT offset pointer into the payload. This pointer designates traffic-block (TDM frame) boundaries. The payload with an attached ATM header forms an ATM cell, and the constructor transmits a stream of the ATM cells to an ATM cell deconstructor of an ATM receiver. The deconstructor disassembles the payloads of the received ATM cells and transmits the stream of frames of constant bit-rate traffic on a talk TDM bus (102). In response to each received SDT offset pointer, the deconstructor's time slot interchanger resets to the start of frame-processing, thereby aligning frames formed by the TSI with the received frames. The deconstructor detects occurrence of TDM frames on the talk TDM bus and synchronizes (aligns) transmission of the frames formed by the TSI with the TDM frames on the talk TDM bus. The listen and talk TDM buses are thereby synchronized with each other.
