摘要： PROBLEM TO BE SOLVED: To facilitate a VLAN setting in a network device and network system for constructing a VLAN at a layer level 2. SOLUTION: A start-edge network device 100_1 adds an address of the device per se and a port number for outputting a construction packet 701 to the construction packet 701 including an address of an end-edge network device 100_6 and a port number corresponding to one VLAN, and transmits the same. An repeating network device 100_3 transmits an address of the device per se, a port number to which the construction packet 701 is input, and the construction packet 701 to which a port number to be output is added. The end edge network device 100_6 transmits a setting packet 702 for corresponding port numbers of the start edge network device and repeating network device to the VLAN for each of them at addresses of the start edge device and repeating network device.

摘要： PROBLEM TO BE SOLVED: To make a device compact, to eliminate the connection error by a maintenance person and to reduce the total number of testing devices to be loaded when connecting a printed circuit board package and testing devices to be loaded on a back wiring board. SOLUTION: A reception part receives a test request signal from an external controller and corresponding to the test request signal, a selection part selects any one of plural testing devices 300a-300m connected to an adapter connector CAN and connects it to printed circuit board packages 212a-212n. It is preferable that a connector for group connects plural back wiring boards 213 and any one of testing devices 300a-300m is selected and connected only to the printed wiring board connected to one back wiring board 213 in that board group by the above selection part.

摘要： PROBLEM TO BE SOLVED: To make a trunk circuit in common to reduce the kinds of the trunk circuit. SOLUTION: The trunk circuit 2d is connected to an opposite device 3 via lines A, B and configured to attain interface control between an electronic exchange 2 and the opposite device according to respective control sequences of a plurality of kinds. When an external device (e.g. an exchange) designates a control sequence to be executed, the trunk circuit sets the polarity of the lines A, B according to the designated control sequence and detects the polarity set by the opposite device through the lines A, B to execute interface control between the electronic exchange 2 and the opposite device 3.

摘要： PROBLEM TO BE SOLVED: To decrease the number of pieces of wiring and to reduce the cost of a subscriber circuit shelf by multiplexing plural control and monitoring signals in time division between a subscriber circuit package and a common package and transmitting and receiving the control and monitoring signals via a single signal line. SOLUTION: A function block F1 of a subscriber circuit package SL1, a function block f1 included in a control part S1 of a common package Ci and a function block Fn of the package SL1 multiplex plural signals in time division and also transmit and receive the control and monitoring signals via a signal line L1, under the control of a function block fn of the part S1 and a time division circuit TD. In the same way, a block F1 of a subscriber circuit package SL32, a block f1 of a control part S32 and a block Fn of the package SL32 multiplex plural signals in time division and then transmit and receive them via a signal line L32, under the control of a block fn of a control part 32 and the circuit TD. As plural signals are multiplexed and then transmitted and received, plural types of signals can be transmitted and received via the least number of signal lines.
