Abstract: A NETWORK ELEMENT TERMINAL DATA INTERFACE (NETDI) system and method incorporating a terminal user interface which permits manipulation of network elements using a hardware-specific control language is disclosed. The present invention teaches automatic generation of on-line help directly from I/O manual specifications and translation of operator commands into network element specific protocols via the use of a network element database and associated XML repository. Various preferred embodiments of the present invention incorporate the use of TL1 composer/parsers to permit the automatic generation of Translation Language 1 interfaces between an operator console and a wide variety of telecommunication network elements.

Abstract: A network wherein a plurality of links connects a plurality of nodes such as cross-connects in a communication circuit network with paths interconnecting the nodes, and with there being spare capacity between a sufficient number of nodes to accommodate at least some rerouting of traffic immediately upon detection of a break in a traffic span in the network so as to restore circuit continuity within a predetermined maximum time using an improved failure detection, isolation, and recovery

Abstract: In a path-based distributed restoration algorithm provisioned telecommunications network, the origin and destination nodes of a failed path are apprised of the portions of the path that remain intact by “reuse” messages that are sent from the custodial nodes that are adjacent to the failure. As each reuse message reaches an intermediate node, the node ID of the intermediate node is appended to a field of the message so that, as the reuse messages are propagated along the intact portions of the failed path, a cumulative list of nodes that are encountered by the messages passing from the custodial nodes to the origin and destination nodes is set forth. Thus, the origin/destination node, when in receipt of a reuse message, can read from the field that has the cumulative list of nodes a description of the intact portions remaining from the original path.

Abstract: To readily isolate a fault in a network adaptable for distributed restoration of disrupted traffic, each node of the network is provisioned with the functionality of being able to detect an incoming alarm signal and convert such alarm signal into a non-alarm signal with an embedded message for further propagation to nodes downstream thereof. Thus, the custodial nodes that first detected the alarm resulting from the malfunction would convert the alarm signal into a non-alarm signal and propagate the non-alarm signal to their respective downstream nodes. By thus changing the alarm signal into a non-alarm signal by the nodes that first detect the alarm, the management of the network ensures that the alarm is detected by only two adjacent nodes, thereby making the fault isolation quick and simple.

Abstract: A system and method for restoring communication between at least one pair of nodes in a network. Distributed intelligence is provided by messaging between adjacent nodes in the network. The messages in combination with user-configurable timers and rules provide fault isolation, forward flooding, reverse linking and connection.
