摘要： PURPOSE:To improve the utilizing efficiency of a line and to prevent ineffective registration by stopping the charging registration of a 5-count circuit at the count state after a called party advanced hook-on is detected in a charging trunk, using a prescribed period of pulse as a forced cut supervisory time and using a periodical pulse to apply forced cut at the called party advanced hook- on. CONSTITUTION:The circuit consists of the 5-count circuit comprising PA-PE relays, a charging registration relay (M relay), a called party response supervisory relay (E relay), a called party response memory relay (CH relay), a line hold relay (CO relay) and a called party advanced hook-on detection relay (COA relay). Moreover, a detour prevention diode D and prescribed period pulse supply terminals PU, AL are provided. The COA relay is operated through the incoming of a prescribed period pulse PU so as to detect the advanced hook-on of the called party. Further, the charging registration is conducted by the operation of the M relay according to an L pulse and as the operating condition, the M relay is activated by the operation of the 5-count relays PA-PE, that is, the PA relay operation and PB relay operation.

摘要： PURPOSE:To ensure the quick and accurate transmission of common information over a wide range, by informing automatically an under-control state to a subscriber terminal from a spot where the traffic is controlled in case a congestion is generated and the calling of the subscriber terminal is controlled. CONSTITUTION:A traffic controller 11 provided in a communication control part 1 transmits the traffic control information to each exchange point 2. This point 2 connects a subscriber terminal 8 to an information tone transmitter 5 when the terminal 8 gives a call to the ground or subscriber under traffic control by the traffic control information. While an information tone reproducer 12 is automatically at the part 1, and the reproduced under-control information tone is distributed to each point 2. The point 2 sends the information tone to the transmitter 5. Thus it is possible to inform an under-control state to the terminal 8. In such a way, the production and transmission of the under-control communication tone are processed in a unitary way through the control network 1. Thus the unitary control is possible for the under-control information tone to ensure the quick and accurate information of an under-control state.

摘要： PURPOSE:To identify the loop start form and the blocking state easily by drawing a signal to a blocking reception circuit of a line drawing device in response to the start form of a succeeding line and relaying the blocking signal to a preceding line. CONSTITUTION:The acquisition state of an outgoing trunk (when an earth signal appears at a terminal C1) is used as the condition activating a TC relay and a method eliminating a defect (a succeeding line is detected to be blocked even when the preceding line is in free state in the loop form) at the start of a conventional TC read. Since the TC relay is not activated at the preliminary blocking from a common device, no B2 terminal (earthing) is detected at the steady state in the loop form.

摘要： PURPOSE:To vary the priority easily, by providing a circuit giving priority information in response to the state of use of a device to be connected for a priority selection circuit. CONSTITUTION:Priority instruction relays AT0-ATN receive an instruction from a scanning control SC, and a corresponding relay among priority selection relays P0-PN receives the priority. When AT2 priority information is received from the circuit SC, for example, the priority instruction relay AT2 is operated, and the operated contacts form the following circuits; 1 ground-at2 operated contact-p2 contact-...(omitted)-atn contact-pn contact-ck operated contact-ato contact-p0 contact-at1 contact-p1 contact-at2 operated contact-P0-PN path is formed, where CK is a check relay and 1 shows ground, and the P2 relay receives the highest priority. Thus, the priority of the relays P0-PN is changed according to the priority instruction relays AT0-ATN received from the SC.
