Abstract: A method and an apparatus for verifying connectivity of a data are applied in the adjacency discovering procedure of the automatically exchanging optical network to verify the connectivity of the data. The method comprises steps: reconstructing the trace object in the SDH coding of the link manage protocol testing message to enable the trace message carry the information of the trace type; when discovering the adjacent layer, constructing the trace message object by the trace agent, sending the trace message to the transmitting plane and requiring the transmitting plane to send the message by the trace byte based on the predetermined form; and when the receiving port of the adjacent layer in the transmitting plane receives the trace message, carrying the different process based on the trace type carried in the trace message. The complexity of realization and the hidden trouble lying in the interconnection caused by the different message sending mechanism in the adjacent layer discovering procedure are resolved, and the transmitting mechanism and the verify flow in the data verifying procedure are unified.

Abstract: In a synchronous hierarchic network having multi-level tandem connection monitoring, all of the fields containing tandem connection monitoring information associated with trail terminations at a subject network element are processed in parallel at the subject network element. The network element extracts the tandem connection monitoring information from received signals independently for each of the tandem connection monitoring terminations occurring at the network element.

Abstract: A transparent optical switch includes network management and performance monitoring using bit level information obtained by extracting selected information on a polling basis and analyzing the extracted information in the electrical domain. In one embodiment, a signal is injected into the switch fabric of the switch via a demultiplexing device. The injected signal is extracted at the output of the switching fabric via an N:1 switch and analyzed by a signal analyzer to verify input to output connections. In another embodiment, an optical switch includes first and second switch fabrics for 1:2 broadcast capability. In a further embodiment, an optical communication system includes a plurality of optical networks and a plurality of optical switches that cooperate to generate unequipped signals and to obtain autonomously switch-to-switch port connectivity information required for auto-topology discovery.

Abstract: The invention discloses a method for transparently transmitting the management information of multi-manufacturer optical synchronous digital hierarchy devices, which defines a set of spare overhead bytes in the frame structure of synchronous transmission module to transfer management information of the other manufacturers, extracts the management information in each node of the transmission network, converts it into a uniform format, determines the transmission direction of the management information of each manufacture by time slot crossing, and inserts the management information of each manufacture into the frame structure of a specified line, the frame structure transfers the management information of each manufacture to the other nodes respectively, the other modes continue to transfer the information in the same way until the management information of the other manufactures is transferred to specified locations respectively. The invention can transparently transmit SDH device management information of the other manufacturers on the SDH device of one manufacturer, and the implementation if simple and reliable.

Abstract: A real time clock request in a communications network is sent from a network element to a management system via a data communications network. The time taken from the sending of the request to the receipt of the RTC is compared with a predetermined maximum and, if less than or equal to the maximum, the network element RTC is updated. If above the maximum the value is discarded and a fresh request is sent. The received acceptable RTC may be corrected by subtracting either the minimum transmission time or half the actual transmission time.

Abstract translation: 通信网络中的实时时钟请求经由数据通信网络从网络元件发送到管理系统。 从发送请求到接收RTC所需的时间与预定的最大值进行比较，如果小于或等于最大值，则更新网络元件RTC。 如果超过最大值，则丢弃该值并发送新的请求。 可以通过减去最小传输时间或实际传输时间的一半来校正接收的可接受的RTC。

Abstract: In an STM-network having multiplexer units (1) and a switch (3), for changes in the traffic configuration memories (41, 49; 43, 51) must also be changed, these configuration memories being located in the multiplexer units for controlling reading and writing in intermediate FIFO-type memories (21, 23). Unsynchronized writing in the configuration memories (41, 49; 43, 51) is avoided by transmitting suitable signals between the configuration memories, in the suitable case on particular lines (53) provided therefor or otherwise by transmitting particular control messages (rec.) which are located in a time slot having a predetermined position in each transmitted frame.
