摘要： PURPOSE:To ensure the immediate transmission of a talkie sound, by discharging immediately a capacitor within a telephone after receiving an originating control signal. CONSTITUTION:When the originating is controlled, a line cut relay 5 is actuated by the control signal supplied from a supervisory tester 6. Then a capacitor within a telephone is discharged in a route of an earth G - a Zener diode 7 - a diode 10 - a discharging resistance 15 - a contact 14a of a timing circuit - a talkie coil 9 - a line cut relay contact 5b - line cut relays 31-3n - cutoff contact 21a-2na - capacitors 11-1n within a telephone - cutoff contacts 21b- 2nb - the earth G. Under such conditions, a talkie sound given from a talkie sound source 12 is just heard through a telephone receiver via the coil 9 although a subscriber telephone has a call.

摘要： PURPOSE:To enable to drive the driven point even if trouble occurs in a driving point information accumulating part and a power source circuit by doubling the control part, the driving point information accumulating part and the power source circuit, and by making a redundant constitution. CONSTITUTION:When control information is transmitted to a control part 20 through a control line 4 by either of common controllers, for example, a common controller 2, the control part 20 transmits the signal which is necessary for driving point control to a driving point information accumulating part 22 and a driving point information accumulating part 23 inside a block 28 of the other side at the same time, and the driving point information accumulating parts 22 and 23 accumulate the same contents. The control part 20 forms the self-system priority signal, transmits it as the selection signal to a selection part 26 through a selection signal line 33, and for a control part 21 inside the other block 28, and transmits the signal which prohibits the operation inside the control part 21 through a signal line between control parts 29. The selection part 26 selects either of driving lines 31 and 32 by the signal from the selection signal ine 33 and a selection signal line 34.

摘要： PURPOSE:To attain safe and sure pull-in to a test circuit by generating a selection signal from a telephone set circuit and utilizing a supervisory relay operated twice during a series of operations so as to control test lead-in relay changeover contacts. CONSTITUTION:A relay circuit D is provided, which activates a test lead-in relay TR so as to change over a switch contact tr when a switch section V is connected to an incoming register trunk IRT and a tested trunk OGT. When the D relay is activated first by the trunk IRT connection, the contact (d) is changed over, a D0 relay is activated and when the D relay is restored through the restoration of the trunk IRT, a D1 relay is activated. When the D relay is activated again through the connection of a metering trunk NRT, the D0 relay is restored. Thus, contacts d0'' and d1'' are connected, the relay TR is activated and the contact tr is connected to the position of a test circuit TST.

摘要： PURPOSE:To secure the channel control with no cross by selecting the channel between the driving unit and each switch grid via the bus selection relay and sharing the bus selection relay among the switch grids to receive the complex selection to secure a simultaneous selection for the corresponding driving units. CONSTITUTION:The selective driving is given to bus selection relay R12 via the bus selection relay driving circuits arranged into a matrix form, and the contact r12 selects the driving paths for switch grids 1 and 2 at one time. And when one of horizontal driving units HDV10-HDV1m plus one of the corresponding horizontal driving units HDV20-HDV2m are driven at one time, the same level is released for grids 1 and 2. After this, either one of vertical path driving units VDV10- VDV1n plus VDV20-VDV2n is driven in corresponding to the channel to be connected to open the intersection with the horizontal level. As a result, no cross is caused even with the release across the channel to carry out the channel control.

摘要： PURPOSE:To decrease the affected range of a fault and to attain stable system and improved service, by splitting a drive line provided in common to plural loads and disconnecting a drive line only corresponding to a faulted part from a control circuit if a fault takes place at a part of the loads. CONSTITUTION:If a fault such as earth fault takes place in a drive line SDL or RDL of a channel drive device SC or a relay device RC, the maintenance personnel operates a key of a drive line control adaptor DVC-ADP mounted on a drive line control frame DVCF in order to prevent the fault of a part from being influenced on the entire system, and disconnects the faulted part. For example, there exists an earth fault on a drive line to a trunk number ''0'' in a trunk frame TRKF0, only a t0 of disconnecting means (e.g., relay contacts) t0-t3 inserted at each line splitting the RC drive line is operated with the control of the drive line control adaptor DVC-ADP so as to disconnect the part from the drive device RC. Then, the fault influencing on the entire trunk frame is located to the range of a half trunk frame.
