摘要： In preferred embodiments, a compact a hybrid integrated circuit device 1 can be provided. A conductive pattern 12 is formed on the top surface of a circuit substrate 10, on the top surface of which an insulating layer 11 has been provided. Conductive pattern 12 is formed over the entirety of the top surface of the circuit substrate. Specifically, conductive pattern 12 is also formed at parts within 2 mm from the peripheral ends of circuit substrate 10. Also, a heat sink 13A or other circuit element 13 with some height can be positioned near a peripheral end part of circuit substrate 10. By arranging hybrid integrated circuit device 1, the degree of integration of hybrid integrated circuit is improved. Thus, in a case where the same circuit as a prior-art example is formed, the size of the entire hybrid integrated circuit device can be made small.

摘要： A redundant path configuration method and a control method are disclosed. An intercommunication path for mutually transmitting and receiving a signal is provided among the BHEs each of which is a top of a tree. When failures occur in an active system path in certain AE, a standby system path (BHE) relays communication between the AE and the (active system) BHE so as to secure continuity of communication. The intercommunication path through which a data signal does not flow in a normal operation is used as a traffic accommodation path in an emergency among the BHEs. By setting a bypass between the tops of the trees, when a failure occurs in one tree, a signal is transferred from the active system BHE to the standby system path in which another BHE is a top to build a sub-tree bypassing the failure point and to secure a communication path.

摘要： A transmission network is comprised of a network management system for collectively managing and controlling a plurality of transmission devices coupled mutually through transmission routes and the transmission network as well. The network management system includes a plane management table adapted to manage transmission planes defined as a set of paths in the transmission network, and the plane management table has the function to set and manage a transmission plane (working plane) applied during normal operation and besides, a single or a plurality of transmission planes (protection planes) applicable in the event of occurrence of a fault in the transmission network. Then, when a fault occurs in the transmission network, the network management system changes the applied plane to a suitable transmission plane.

摘要： It is necessary to completely remove overlapping of signals between plural PONs in order to make the PONs coexist. Accordingly, it is required to share or intensively manage bandwidth use conditions over an optical fiber that serves as a common band between plural systems. Therefore, transmission clocks should be synchronized with high accuracy between plural systems. A reference clock is provided from an external device or a representative OLT to the entire systems to perform clock synchronization between plural systems, so that the overall systems are synchronized by synchronizing each OLT with the reference clock. A hierarchical management method is selected that manages ONUs under the control of each OLT by managing band use information arranged for each OLT with respect to an external device or a representative OLT for sharing of bandwidth use conditions between plural systems.
