摘要： PROBLEM TO BE SOLVED: To provide an ISDN communication system for improving a communication speed and reliability. SOLUTION: When a center 3 transmits a meter inspecting request message, etc., to I-NCU 7, the center 3 sets a starting message, etc., to UUI(user-user information) of a SETUP message to transmit to I-NCU 7, which does to set an answering message to a DISC message but transmits it to the center 3. An answering message from a terminal side is set to the UUI(user-user information) of the SETUP message from I-NCU 7 as a new call to transmit to the center 3. In contrast, when the center 3 transmits a command message or an answering message, the center 3 sets the command message or the answering message to the UUI(user-user information) of the DISC message to transmit to I-NCU 7.

摘要： PURPOSE:To reduce the battery consumption of a radio slave machine attached to the automatic gauge examination meter side in the automatic gauge examination system of the radio start system. CONSTITUTION:A strong radio wave reception circuit 14 capable of always receiving a radio wave is built in a radio slave machine 12 on the side of an automatic gauge examination meter 15, and the gauge examination start radio wave transmitted from a gauge examination center 1 is temporarily received by the circuit 14 to start a weak radio circuit 13 of the radio slave machine 12. Since the power consumption of the strong radio wave reception circuit 14 is low and the weak radio circuit 13 of high power consumption is turned off except at the time of gauge examination, the battery consumption is low. Thus, the radio slave machine 12 on the automatic gauge examination meter side can function for a long term without replacing the battery.

摘要： PROBLEM TO BE SOLVED: To obtain an ISDN communication system having high line efficiency and reliability. SOLUTION: When a user performs calling communication to a center 3 side from a meter 13 side by using user/user information communication service, there are cases where a user exchange 9 of a network sometimes decides it as congestion, so that the meter 13 side may receive response corresponding to the condition of being in the midst of a conversation. For instance, an NCU 11 sets telegraphic message to a UUI(user/user information) of a SETUP message and transmits the SETUP message to the user side exchange 9 (step 204). While the exchange 9 decides it as congestion, the exchange 9 returns a REL 21 (release) message, where busy 28 or usable line unavailable channel 29 is set to a reason flag 27 corresponding to the condition of line being busy (step 206). Congestion is decided from the REL 21 (release) message received by the NCU 11, and a retry is performed after prescribed time that is shorter than a normal retry passes, (e.g., four seconds) (step 208). When the response corresponding to the condition of line being busy is received, the NCU 11 repeats retries for a prescribed number of times.

摘要： PROBLEM TO BE SOLVED: To facilitate the connecting work, and to prevent the generation of short-circuit by pinching parts to be pinched, which are respectively provided in a pair of terminals, with a first and a second pinching parts. SOLUTION: A first pinching part is formed of plate springs 3a,. 3c and rollers 5a, 5c, and a second pinching part is formed of plate springs 3b, 3d and rollers 5b, 5d, and both the pinching parts are formed of conductors such as metal. A terminal 117a and a setting unit 111 are electrically continued to each other through a tab 119a, the roller 5a, the plate spring 3a and a cord 7a, and similarly, a terminal 117b and the setting unit 111 are electrically continued to each other through a tab 119b, the roller 5b, the plate spring 3b and a cord 7b. In the case of connecting the setting unit 111 to a pair of terminals 117a, 117b provided in a T-NCU 103, they are connected by only pushing the first and the second pinching parts into the tabs 119a, 119b, and the connecting work is facilitated. Since a constant space is maintained between both the pinching parts, generation of short-circuit is prevented.

摘要： PROBLEM TO BE SOLVED: To grasp the remains of battery capacitance in a net controller. SOLUTION: The net controller 5 addes and stores an incoming communication time from a center 1 and the originating communication time of alarm, etc., in RAM 11 and reports the communication times to the center 1. The center 1 monitors and controls the transmitted communication times in terms of constant quantity and extimates the remains of battery capacitance. The proper exchange period of the net controller 5 is estimated by the estimated remains of battery capacitance and the net controller 5 is exchanged at the exchange period.

摘要： PURPOSE:To make a system superior in privacy and to eliminate the complicated procedure by spectrum-spreading a data signal, FSK-modulating it, transmitting it by a weak radio wave conforming a radio law, receiving it, spread spectrum demodulating it and fetching data. CONSTITUTION:The data signal is spectrum-modulated in a spread spectrum modulation circuit 2, is FSK-modulated in an FSK modulation circuit 3 and is transmitted by the weak radio wave through a transmission antenna 4 on a transmitter 1-side. On a receiver 5-side, a weak radio wave signal received in a reception antenna 6 is FSK-demodulated by an FSK demodulation circuit 7, is spread-spectrum demodulated in a spread spectrum demodulation circuit 8 and the data signal is fetched. Thus, a system can easily be used without the complicated procedure since the weak radio wave conforming the radio law is used. Furthermore, privacy is superior, a strong resistance to the interference by a third person exists and interference to others hardly exist by adopting the spread spectrum modulation system.
