    摘要： The invention relates to SDH digital cross-connects, in particular to their management systems. The invention is directed to an arrangement by means of which the connections of 64-kbit/s channels, for example, can be defined in the SDH network element in a manner that requires considerably less memory than the prior art arrangements. In the arrangement according to the invention, the cross connection data are concentrated in one element, namely, a special cross connection object (205). TP objects (210) are not created one per each lowest-level channel but one per each certain higher-level channel (215), such as a 2-Mbit/s channel in typical voice traffic. Data about the lowest-level channels, such as 64-kbit/s channels, are presented in a centralised manner in the TP object of each 2-Mbit/s channel in tabular or other such form. In the arrangement according to the invention, objects are not created nor removed when creating, changing or removing cross connections, but only the parameters of said cross connection object and TP objects are changed. Such an arrangement facilitates the transfer of data on a large set of cross connections from an administrative unit to the SDH network element in one message and the transfer of a great number of connection changes at one time from the cross connection object to the switching equipement in the SDH network element.

    摘要： A heterogeneous telecommunications system employs "out of band" signalling to automatically discover the identity of the two ports connecting two network elements through a specific link. Either of the connected network elements may be a circuit switching network element or a packet switching network element. One network element initiates the port discovery process and transmits an overhead signal, such as a SONET/SDH protection switching message, to the network element attached at the other end of the link. The other network element monitors the status of its ports and, when it detects a change in state at one of the ports, resulting from the first network element's transmissions, the receiving, or passive, network element recognizes the port as the port which forms a part of the link of interest. Each group of network elements, packet switching and circuit switching, elects a network element leader which coordinates requests for port identification.

    摘要： A method and arrangement for opening and closing communication channels by means of a private branch exchange is described. The transport network for transport of communication data is preferably embodied as an ATM network, controlled by a separate control network. In one particular version all decentralized relaying units are connected to each other via the transport network by means of virtual pathways. This guarantees that the formation of links via the transport network between any communication subscribers takes the same time. The time delay in forming a link only occurs during the initialization process of the transport network when virtual communication links are set up in the transport network.

    摘要： An apparatus and a method for forwarding data packets through a fiber optic ring network includes forwarding data packets on a packet by packet basis. A node (300) on the fiber optic ring network decides on a packet by packet basis whether to transmit on the working or protection path. Because this decision is being made on a packet level, reservation of throughput resources no longer is made at a one to one ratio. Rather, protection path resources are reserved at a ratio significantly less than one to one. In one embodiment, no resources are reserved for path restoration or protection path routing. Rather, quality of service provisioning is used to resolve interference situations wherein instantaneous demand exceeds capacity. A node (300) evaluates ring conditions in relation to the demand of traffic resources and the relative quality of service ratings to determine whether and how to forward a packet. Additionally, a node (300) decides whether to use the working (332) or protection path (336) by considering the final destination on the fiber optic ring network, any identified ring conditions and, in some embodiments, quality of service. The ring conditions to which the inventive nodes respond include OSI layer 1, layer 2 and layer 3 conditions. In alternate embodiments, the node (300) also evaluates parameters such as identified or assigned quality of service parameters. Whenever a layer 1, a layer 2 or a layer 3 condition occurs, a node generates an overhead signal within fifteen milliseconds of the condition occurring. An ingress node (a node that receives IP traffic and places it onto the fiber optic ring network) is adapted to effectuate path restoration within 35 milliseconds of receiving the overhead signal identifying a failure and within fifty milliseconds of the failure condition event.
