摘要： In order to support both signalling processing on a per channel basis and multiple adaptation protocols, an interface (10) is modularised principally by function. Incident channels (60-62, Cho—Chn) are applied to a routing device (16) that consults a connection map (64) to determine an appropriate path, via an interface (90), for signal processing of each channel, as shown in FIG. 2. Modularised processing platforms (70-74) each contain a number of signal processors (80-86), with each processing platform providing an additional level of indirection with respect to channel handling. In this latter respect, one of the signal processors (86) on each platform is assigned to distribute channel processing to appropriately configured other ones of the signal processors and such that signal processing functions may be distributed between the other ones (80-84) of the signal processors. The present invention is particularly useful in relation to a narrowband-broadband interface to support differing adaptation protocols that require different signal processing functions and also to vary signal processing capabilities on a per call basis.

摘要： A method and apparatus for handling persistence measurement of channel associated signaling for a plurality of line circuits, eg, T1, E1, OC3, STM 1 circuits, which extracts channel associated signaling data from a plurality of line circuits; assembles the channel associated signaling data into a data frame; contains the data frame in a suitable carrier, eg, an AAL 0 cell; monitors a continuous stream of the data frames, to check for changes in line status; and generates an event message data frame when a persistent change of line state has been detected. The extracting of associated signaling data may be provided on a separate card to a call control processor, and using separate processor functionality. A data processing load of a prior art call control processor which would otherwise be taken up in channel associated signaling persistence measurements may be alleviated, and the data processing burden on a prior art call control processor for handling persistence measurements is separated off and handled by the data processing apparatus and method according to the present disclosure.

摘要： An arrangement for interfacing between TDM and ATM networks consists of a family of devices that comprises two groups. The first group comprises devices that perform multiplexing, segregation and routing field translation for the respective traffic type. They may also remove or substitute an outermost layer of encapsulation. These first group devices are bi-directional and output buffered with respect to the network. The second device group comprises devices that perform format conversions between the service payload (voice, video or data) and an adaptation layer control format. These second group devices are also bi-directional and buffering depends on the particular function, e.g. real-time, segmentation.

摘要： To obviate inefficient use of bandwidth in a packetised system, such as a broadband ATM domain, the use or amount of header information sent in relation to a channel is restricted by one of two principal mechanisms, as exemplified in FIGS. 3 and 4. First, control information incident to a packet interface (20) is interrogated by a processor (21) to determine (50) packet length requirements. A packet length indicator is then generated (52) for inclusion within a header (44) of a packet. Alternatively, a frame (30) is pre-partitioned (60) into several packets (32-42) having different lengths. An addressed subscriber unit (28) is allocated (64) a particular channel, i.e. at least one particular packet within the frame (30), based on data throughput requirements (62), whereby the location of the packet within the frame inherently identifies the length of the packet. Optionally, the data rate used within that packet may also be identified inherently by the location of the packet within the frame (30).

摘要： A telecommunications system comprises an asynchronous transfer mode (ATM) network having uncommitted bandwidth, and a plurality of adaptive grooming routers (AGR) coupled to the network. The AGRs comprise a group adapted to function as a virtual transit exchange whose fabric and control are distributed over the group. The virtual comprising the AGRs incorporates independent connection control and call routing functions and has means for determining the current system status whereby to set up narrow band connections across the ATM network based on that status determination.

摘要： Communicative services are transported over a TDMA or TDM access network by packetising the services into minicells which minicells are transported within minislots created by subdivision of the TDM time slots. For low bit rate communicative services only, mini-slots are allocated periodically rather than in the blocks that are allocated to high bit rate services. The packetisation delay inherent within the transport layer can be significantly reduced for these low bit rate services.

摘要： A data structure, such as a telecommunications connection map, comprises at least one list of data elements which are stored in a predetermined sequence of locations of a memory device. The structure is updated by moving a portion of the list through the sequence of memory locations so as to insert a new element into, or delete or change an existing element at, a particular position in the structure while maintaining the order of the list. Elements of the structure are accessed in the sequence in which they are stored and the structure is updated during the accessing of the structure by moving elements through the sequence of memory locations. A particular application of this invention is in maintaining a connection map for a telecommunications switch, the map storing connection instructions defining into which ATM cell payload received narrowband call data is assembled.

摘要： An interface arrangement provides interfacing between a frame based telecommunications network in which traffic is transported in frames and an asynchronous network in which traffic is transported in cells or packets. Each TDM frame supports a plurality of data structures each comprising one or more channels. Credits corresponding to bandwidth entitlement are issued at a substantially constant rate and are assigned to the data structures according to the size of those structures by a connection control. Each data structure is accorded a threshold number of assigned credits, and when this number has been reached, the data structure is assembled into cells or packets for dispatch into the asynchronous network.

摘要： The invention relates to a method and apparatus for multiplexing traffic from a plurality of fixed bit rate sources over an ATM network. The traffic from the fixed bit rate users is multiplexed to form a TDM trunk group which is assembled into AAL2 minicells prior to being converted to ATM cells for transmission on the ATM network. By combining the fixed rate traffic sources into a TDM trunk group and then mapping the trunk group into AAL2 minicells, it is possible to improve efficiency of fixed bit rate traffic transmission using the ATM protocol.
