摘要： A method and system for optimizing transmission links bandwidth utilization in an Asynchronous Transfer Mode (ATM) packet switching network including switching nodes interconnected by high speed transmission links, said network being made to transport user data traffic including PTM traffic organized into variable length packets, each packet comprising a variable length data payload and an original fixed length PTM packet header. The original PTM header is converted into an ATM-like header including a flag (F) identifying the packet as being a PTM packet, a label indication made to orient the currently-considered PTM packet within the ATM network nodes, a count (CNT) field for storing the PTM payload length indication therein to enable locating the PTM payload end position and a Header Error Control (HEC) field for storing an ATM-like error control byte (HEC) therein, which enables transporting the PTM packets over the ATM network links without having to chop the PTM payload into predefined fixed length segments by adding dummy bits to the last segment if required.

摘要： A system for coding voice signal to optimize bandwidth occupation in a High Speed Packet Switching network while ensuring best voice transmission quality.The voice signal is first encoded using a conventional GSM like RPE/LTP coder providing first sub-frames of coded signal and tagging these first sub-frames as being non-discardable. In addition, a convenient difference between an RPE/LTP provided signal and a corresponding synthesized image is performed (see 36) and is also block encoded into second sub-frames which second sub-frames are tagged as being discardable sub-frames. Said second sub-frames when concatenated to corresponding first sub-frames provide so-called multirate frames. Then, when transmitting said multirate frames over the High Speed packet switching network, dropping discardable tagged data enables solution network congestion situations in any network node and at random with no significant disturbing effect over the voice communication operation.

摘要： A packet switching communication system is improved by using a packet header structure which does not require a fixed format. The packet header comprises a chain of 2 byte command/data segments. Each command/data segment contains generic bits and a routing field. One of the generic bits (bit 1) allows the header to be extended with another command/data segment.

摘要： A method of integrating the switching of voice and data between terminals connected to switch adapters. The switching of voice (or more generally synchronous signals) is accomplished by grouping voice samples in a first adapter and bound for the same destination or second adapter into a frame. Connections are then established between the two adapters and the frame is transmitted therethrough. A duplex method can also be set up by transmitting in both directions at the same time once a dual connection between the first and second adapter is established. Hence, a second group of voice samples bound for the first adapter is also formed ina frame. The two frames are then transmitted simultaneously in opposite directions through a dual connection in the switching matrix. Data is switched by storing data in respective memories of respective adapters, wherein each respective memory corresponds to a particular adapter to which the data stored therein is to be sent.

摘要： A method and apparatus to provide high speed voice/data switching with efficient utilization of available bandwidth and minimal switching delay. More specifically, this invention uses shift registers at each crosspoint of a switching matrix. In each slot position of the register, there is a bit representing the status of an associated crosspoint during a particular time slot. Each slot position of the register represents a different time slot. The status of the crosspoint changes in accordance with the bit that is in a designated slot position during each time slot. During each time slot, at most one bit of data/voice is then transmitted through any given closed crosspoint.

摘要： A switching network for selectively connecting at least one input time-division channel on an input link (IL) to at least one output time-division channel on an output link (OL). The network is organized around a closed-loop link (10) on which circulates a multiplex message carrying 512 time-division exchange channels. The input and output links (LE and LS) are respectively multiplexed onto an input multiplex link (IML) and an output multiplex link (OML) which are coupled to the closed loop (10) by a switching module (SM). Each switching module comprises an input buffer (IB), an output buffer (OB) and a local buffer (LB) the addressing of which is selectively controlled by a time slot counter (CRT) or a corresponding pointer memory. So-called "broadcast" connections coupling one input channel to several output channels, and "in-cast" connections coupling several input channels to one output channel, can be established. Each of these connections uses only one exchange channel.

摘要： The contents of input time-division channels on a closed-loop link (10LO, 10HI) are stored in a memory (173) at the address supplied by an input address counter (IAC) controlled by an incoming timing signal (2MCR). The memory is read out under control of an output address counter (OAC) controlled by an outgoing timing signal (2MCT). Each time interval is divided into one read period and two write periods. Means (186) are provided to select one of the two write periods dependent on the phase relationship between the incoming and outgoing timing signals. The units connected in series by means of the closed-loop link receive a timing signal circulating on a timing loop (15) that is closed by a master timing device (13). Slave timing devices (18) inserted in the timing loop regenerate the timing signals circulating thereon and check same.
