摘要： PURPOSE:To simplify a test system and a test procedure by using a test equipment integrating a function test equipment for a subscriber circuit, a transmission characteristic test equipment and a termination circuit. CONSTITUTION:A subscriber circuit 13 has a test use drawing line 11 connecting to an external test equipment in place of a subscriber line and receives and sends a voice signal and control information in place of a line concentrator 12. The function test is implemented by a function test means 14 via the test use drawing line 11 and a line terminator 12. A transmission characteristic test is implemented by allowing a termination means 16 to terminate a subscriber line circuit of the subscriber circuit 13 via the test use drawing line 11 and using a channel formed by a transmission characteristic test means 17 via the line concentrator 12. Since the test equipment 15 having the function of the subscriber circuit 13 and able to test the transmission characteristic is used to implement the function test and the transmission characteristic test by one test procedure, the test procedure is simplified.

摘要： PROBLEM TO BE SOLVED: To automatically provide processing which shifts from complaint call receiving to a test state by making a test trunk give telephone number information that is automatically notified to an electronic exchange when an maintainer performs a test start, making the electronic exchange set up a test path which connects a workstation, the test trunk, a subscriber's test device and a subscriber and shifting to a subscriber's test state. SOLUTION: A CC (central processor) notifies a subscriber's number that is already stored to a CATI (dedicated complaint call receiving trunk) after shifting to a speech communication state for receiving a complaint call between a subscriber and a maintainer as for an operation of this complaint call processor. This telephone number notice 14 is further sent as a telephone number notice from the CATI to a CBOX and it is further sent as a telephone number notice 16 from the CBOX to a TWS (workstation). The TWS stores the subscriber's number included in the notice 16 as internal data and also displays it on a display. The maintainer requests a test activation from the TWS.

摘要： PROBLEM TO BE SOLVED: To mitigate power loss in power transmission by immediately responding to power excess and deficiency.SOLUTION: A control device of a smart meter established in each region having power generation equipment and power storage equipment has a storage unit, a selection unit, and a transmission/reception unit. The storage unit stores an evaluation value related to a power transmission load with other regions connected by a power transmission network and a communication network, in association with income and expenditure of power of other regions for each of other regions. The selection unit selects the other region to be a request destination of power transmission based on the evaluation value and the income and expenditure of power stored by the storage unit, when the income and expenditure of power of the own region is smaller than a predetermined threshold. The transmission/reception unit transmits a request that power should be transmitted from the other region to the own region through the power transmission network, to the other region selected by the selection unit via the communication network. Coordination between transmission from the selection unit and a switch enables the power transmission request and switching control to be executed simultaneously.
