摘要： The present invention refers to methods and apparatuses for providing synchronization in a time division multiplexed network, wherein data is transferred on multi-access bitstreams in circuit-switched channels that are defined by respective time slots of regularly recurrent frames of said bitstreams, said frames being defined by regularly recurrent frame synchronization signals transferred on said bitstreams. According to the invention an auxiliary regularly recurrent frame synchronization signal is generated and selected as a basis for defining said frames on a bitstream if the frame synchronization signal that is used as a basis for synchronizing said frames during normal operation is not detected in accordance with an expected frame rate.

摘要： The present invention refers to methods for establishing control signaling between nodes connected to the same communication link, said link carrying a bitstream that is divided into frames, each frame in turn being divided into time slots, said time slot being allocatable to define circuit switched channels.According to the invention, all nodes connected to said link using, at link start-up, the same predefined time slot or set of time slots in said frames to receive control signaling messages from and transmit control signaling messages to nodes connected to said link. The nodes then establishes, using control signaling via said predefined time slot or set of time slots, respective control channels, defined by respective time slot or set of time slots in said frames, reserved for transmission of control signaling messages from each respective one of said nodes. Based thereupon, each respective one of said nodes uses, when having been established such a respective control channel, said control channel to transmit control signaling messages to other nodes connected to said link, the other nodes accessing this control channel only for receiving control signaling messages.

摘要： A method and an arrangement for synchronizing two more individual communication networks of the time multiplex type, in order to form a composite network thereof, wherein the individual networks having nodes, in which cyclic transmission of time frames is performed, which include time slots intended for the data transmission. One node in the composite network is assigned the role as a superior master node determining the transmission speed of the individual communication networks. This is obtained by adding a fixed idle pattern to each time frame set out from the superior master node, followed by a fixed triggering pattern as a start of the next time frame. At the receipt of the triggering pattern at a master node in an individual communication network, which synchronizes the data transmission of the communication network, the master node starts sending a new time frame.

摘要： The present invention relates to a defragmentation method and arrangement for increasement of the average block size of free tokens in the nodes of a DTM (Dynamic Synchronous Transfer Mode) network. The defragmentation comprises defining a home node for each token at network startup in such way that the tokens sharing the same home node will always define at least partly a continuous slot range, sending back free tokens to home nodes when a significant time has passed and, merging two or more slot-consecutive tokens with the same slot range into a single token when existing in the free pool of a node. The defragmentation can be realized in a central or a distributed token management scheme.

摘要： A technique is provided for allocating access to time slots used for transferring data between nodes in a time multiplexed network, whose bandwidth is divided into cycles. The cycles are in turn divided into control slots for control signaling and data slots for transferring data. The slots allocated to a primary home node may be temporarily allocated to a temporary home node, in which case the temporary home node, instead of the primary home node, then temporarily has the write access to the slots. The slots may subsequently be reallocated to the primary home node. In particular, the degree of temporary allocation of slots to a first node is evaluated. Then, the number of slots having the first node as a primary home node may be increased based upon the evaluation. This decreases the need for temporary allocation of slots within the network.
摘要翻译：提供了一种技术，用于分配对用于在时分复用网络中的节点之间传送数据的时隙的访问，时间复用网络的带宽被划分为周期。这些周期又分为用于控制信令的控制时隙和用于传送数据的数据时隙。分配给主要家庭节点的时隙可以临时分配给临时家庭节点，在这种情况下，临时家庭节点，而不是主要家庭节点，然后暂时对这些时隙进行写访问。这些时隙可以随后被重新分配到主要家庭节点。具体地说，评估到第一节点的时隙的临时分配的程度。然后，可以基于评估来增加具有作为主要家庭节点的第一节点的时隙的数量。这减少了对网络中的时隙的临时分配的需要。
