摘要:
A bi-directional line switched ring network system including a plurality of optical fiber communications lines and a plurality of nodes connected by the plurality of optical fiber communications lines forming a closed circuit. Each of the nodes performs an addition and a drop of a path between an external communications apparatus and the optical fiber communications lines or permits the path on the optical fiber communications lines to pass through, or performs a change of a direction of the path. A control unit is located in each of the nodes to control the addition, the drop, the pass-through and the direction change of the path. When the path passes through each of the nodes, the control unit sets a time slot number of the path in being inputted into the node and a time slot number of the path in being outputted from the node independently of each other.

In a transmission network including multiplex transmission units A, F, G, D and E, when the line breakage has occurred on the OC-12 transmission path of the direction from unit A to unit F, the unit F detects the signal coming in from the OC-12 path indicative of the line breakage. The unit F inserts the APS bytes which comes in from the unit A into the undefined area of the OC-192 transport overhead which is reserved for the through-transport of APS bytes, and transports it to the unit G. On receiving the through-transport APS bytes, the unit G inserts it intact into the defined area for the APS bytes in the OC-12 transport overhead, and sends it to the unit D. In this manner, protection switching between the units A and D is carried out.

A terminal multiplexer is constructed in such a manner that it can be upgraded for adapting to a change in a transmission system. Line terminating equipment (LTE) having working high speed transmission lines and protection high speed transmission lines in 1:1, is constructed from such units as two sets of 10G interfaces responsible for interface with the high speed transmission lines, and SELH which selects a high speed transmission line for which multiplex conversion is performed in relation to low speed transmission lines When this LTE is to be upgraded to ADM adapted for 2-Fiber BLSR, the unit SELH is replaced with SWH which performs switching of signals in each time slot between a high speed transmission line and the low speed transmission lines. Upgrading during the system operation is possible by making signal interfaces with the outside common for SELH and SWH, and by making delay times between signal input and output coincide for various signals.

A metal member includes a first layer and a second layer. The second layer has an average crystal grain size different from an average crystal grain size of the first layer. An intermediate layer having an average crystal grain size smaller than the average crystal grain sizes of the first layer and the second layer is interposed between the first layer and the second layer.

An image processor includes an encoding unit encoding inputted data. The encoding unit includes a first processing unit splitting the data into a first partial data in a first digit range on an upper side and a second partial data in a second digit range on a lower side, a second processing unit encoding only the first partial data between the first partial data and the second partial data, and a third processing unit performing correction to set a value of the first partial data at “0”.

A smart entry system for a vehicle having a lockable trunk is provided. The smart entry system includes portable devices, an onboard transmitter for transmitting request signals to the portable devices, an onboard receiver for receiving identification signals from the portable devices, and a trunk lockout protection feature. The trunk lockout protection feature is configured to receive a command signal to either initiate a trunk lockout protection sequence to unlock the trunk in the event that one of the portable devices is locked in the trunk or to disable the trunk lockout protection sequence to permit the trunk to remain in a locked state in the event that one of the portable devices is locked in the trunk.
