摘要： A data packet format includes an important information field in a data packet header or payload, e.g., a transport format indication field including one or more indicating the transport format for the data packet. It also includes one or more error correction bits associated with the important field, (e.g., the transport format indication field), usable by an error correction scheme at a receiver to correct errors in the received header. An error detection field in the data packet is used at the receiver to detect such bit errors. In one example implementation, the one or more error correction bits are positioned in spare or unused bit locations in the data packet. In a further implementation, one or more unused bits in the important data field are used to carry the one or more error correction bits. A particular example is the use of one or more most significant bit positions of the important data field to carry error correction bits while remaining less significant bit positions carry important data information. Alternatively, spare or unused bit locations in multiple data packets may be used to carry error correction bits. Still further, in a transport format indication field example, the error correction information may be determined by the receiver based on a set of available transport format combinations.
摘要翻译：数据分组格式包括数据分组报头或有效负载中的重要信息字段，例如包括指示数据分组的传输格式的一个或多个的传输格式指示字段。它还包括与重要字段相关联的一个或多个纠错位（例如，传输格式指示字段），可由接收器处的纠错方案使用，以校正接收的报头中的错误。在接收器处使用数据包中的错误检测字段来检测这样的位错误。在一个示例实现中，一个或多个纠错位位于数据分组中的备用或未使用位位置。在进一步的实现中，重要数据字段中的一个或多个未使用位被用于承载一个或多个纠错位。一个特定的例子是使用重要数据字段的一个或多个最高有效比特位置来携带纠错比特，而剩余较低有效比特位置携带重要的数据信息。或者，可以使用多个数据分组中的备用或未使用的位位置来携带纠错位。此外，在传输格式指示字段示例中，纠错信息可以由接收机基于一组可用的传输格式组合来确定。

摘要： An AAL2 path group ( 60 ) comprises plural AAL2 paths ( 35 ). Bandwidth of an individual AAL2 path comprising the AAL2 path group is contributed to a total bandwidth of the AAL2 path group rather than to the individual AAL2 path exclusively. An admission decision regarding a connection seeking to use an AAL2 path belonging to the AAL2 path group is based on available bandwidth of the AAL2 path group rather than available bandwidth of an individual AAL2 path. ATM VCCs which comprise the AAL2 path group are transported on a virtual path (VP) together with ATM VCCs of a different type (e.g., a second type which differs from a first type of ATM VCC which comprise the AAL2 path group). The AAL2 path group also features quality of service (QoS) separation, e.g., differing treatment for differing AAL2 connections within the AAL2 path group based on the QoS requirements for the differing AAL2 connections.

摘要： The present invention provides interconnection links between modules in a switch node. A redundant physical link couples the modules and a dual state data packet routing tag is used to identify which link is active. A standard tag received from an application device is converted to the dual state data packet routing tag, after the data leaves the application device so the interconnection link routing is essentially invisible to the application layer.

摘要： A telecommunications system has a protocol architecture over an interface between nodes of the telecommunications system, the protocol architecture including Internet Protocol as a protocol above a link layer protocol in a transport network layer. The protocol architecture can be used over one or more of several interfaces, including the interface between a radio access network and a core network [Iu Interface]; the interface between radio network controllers (RNCs) and the base stations (BSs) served thereby [Iub Interface]; and the interface between a Source RNC (SRNC) and a Drift RNC (DRNC) [Iur Interface]. A new XTP Protocol is proposed as another aspect of the invention, which is usable in a protocol stack for the Iu-PS (packet switched) implementation as well as over the Iu-CS, Iub, and Iur Interfaces.

摘要： The present invention relates to a telecommunications system, nodes, device boards and methods in such telecommunications systems, where a node comprises a first device board, which includes a receiving section (25) having at least one input port (29, 31, 33), to which an input buffer (30, 32, 34, 36, 38, 40) is connected for receiving TDM-channels in TDM-frames, and having at least one transmitting buffer (42, 44, 45). A second device board includes a transmitting section (27) having a receiving buffer (48, 50, 51) for every other device board, at least one output port (59, 61, 63) and at least one output buffer (52, 54, 56, 58, 60, 62) for every output port. All TDM-channels received in input buffers intended for the transmitting section are copied to a corresponding transmitting buffer and the content of the transmitting buffer reaches the transmitting section through sending of at least one transport module solely containing all TDM-channels intended for said second device board. The transport module is received in a corresponding receiving buffer in the transmitting section and all TDM-channels in all receiving buffers to be sent in a frame via an output port are copied to the output buffer corresponding to said port.
