摘要：根据本发明实施例的电信交换局的交换机根据预定ATM－VCC(异步转移模式－虚信道连接)使入局TDM(时分多路复用)帧中的时隙适合于ATM帧,并且根据经由交换局的ATM交换机构(40)承载的连接的变化数目、动态地改变用于预定ATM－VCC的ATM帧中ATM信元的数目。交换局包括ATM交换机构、发送端口(100)以及接收端口(200)。在经ATM交换机构选择从发送端口到接收端口的路由的ATM帧中承载带内同步信号,以便根据连接的变化数目调整发送端口与接收端口之间变化的帧结构。根据一种实例实施方案,用于预定ATM－VCC的ATM帧中ATM信元的数目在1到64之间变化,而且用于预定ATM－VCC的ATM帧中的一个ATM信元输送11个时隙。

摘要： Disclosed herein are devices and methods for communicating full-rate voice data under an ATM protocol. An exemplary device is configured to communicate voice data through a vocoder in a CDMA backbone network using an ATM Adaptation Layer 0 (AAL0) cell-generating system, which is configured to generate an AAL0 cell for each frame of full-rate voice data. In an exemplary embodiment, the device generates AAL0 cells that each comprise (a) 5 bytes of a Header field; (b) 1 byte of a Length field indicating a size of the voice data; (c) 24 bytes of a Voice-Data field containing the voice data; (d) 19 bytes of a Control-Data field containing information for controlling the voice data; (e) 1 byte of an Error-Detection field containing information for detecting an error of the voice data; and (f) 3 bytes of a PAD field for padding data used to exactly fit into the ATM cell.

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： The present invention relates to an Asynchronous Transfer Mode (ATM) protocol, and more particularly to an ATM Adaptation Layer 0 (AAL0) cell format for increasing trunk path efficiency when communicating voice traffic data by using the ATM protocol in a CDMA system. In a conventional CDMA system, the ATM is used to communicate multimedia traffic, including voice traffic data, through a backbone network, and AAL5 cell is most widely used in the ATM since it provides a simple and efficient process for data traffic. However, when processing full-rate voice traffic (i.e., 24 bytes of voice data per 20 ms-frame), two AAL5 cells are needed to communicate the full-rate voice data because one AAL5 includes only 16 bytes of data. This may result in few problems (e.g., traffic overload, cell loss and so forth). In order to eliminate the above problems, the present invention employs an AAL0 cell, in which 8 bytes of trailer are sacrificed and assigned to the voice traffic data, to enhance trunk path efficiency.
摘要翻译：本发明涉及一种异步传输模式（ATM）协议，更具体地涉及一种ATM适配层0（AAL0）小区格式，用于在CDMA系统中通过使用ATM协议来传送话音业务数据时增加中继线路效率。在常规CDMA系统中，ATM用于通过骨干网络传送包括语音业务数据的多媒体业务，并且AAL5小区在ATM中被广泛使用，因为它为数据业务提供了一种简单有效的过程。然而，当处理全速率语音业务（即，每20ms帧的24个字节的语音数据）时，需要两个AAL5单元来传送全速率语音数据，因为一个AAL5仅包括16个字节的数据。这可能导致很少的问题（例如，流量过载，信元丢失等等）。为了消除上述问题，本发明采用AAL0小区，其中8字节的预告片被牺牲并分配给语音业务数据，以增强中继线路径效率。

摘要： The switch for a telecommunications exchange in accordance with an embodiment of the invention adapts a time slot in an incoming TDM-frame to an ATM frame in accordance with a predetermined ATM-VCC, and further dynamically changes a number of ATM cells in the ATM frame for the predetermined ATM-VCC in accordance with a changing number of connections carried through an ATM switch fabric (40) of the exchange. The exchange comprises the ATM switch fabric; a sending port (100); and a receiving port (200). An inband synchronisation signal is carried in an ATM frame routed through the ATM switch fabric from the sending port to the receiving port for coordinating a changing frame structure between the sending port and the receiving port in accordance with the changing number of connections. According to one example implementation, the number of ATM cells in the ATM frame for the predetermined ATM-VCC varies between one and sixty four, and one ATM cell in the ATM frame for the predetermined ATM-VCC convey eleven time slots.
