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 provide a user/user information transfer method where transmission reception of a user/user information is finished in a short time by continuously transmitting a plurality of UUI sets through one call control sequence by a transmission terminal and number of network resources required for the transmission reception of the UUI can be reduced and to provide an information transfer terminal. SOLUTION: In the transfer of the user/user information included in a call control message of an ISDN line exchange service, a transmission terminal includes a part clearly indicating continuous transmission of the user.user information to the user.user information included in a setup message and transmits the resulting user.user information, a receiver terminal receives the user.user information included in the setup message together with the part clearing indicating the continuous transmission of the user.user information, the receiver terminal confirms the validity of the received information, immediately returns the setup message and waits for an interruption restoration sequence started from the transmission terminal as it is.

摘要： PROBLEM TO BE SOLVED: To solve a problem of an increased reply time in the case of continuously transferring user-user information by receiving the user-user information included in a setup message, confirming the validity of the reception of an incoming call, then immediately returning a call message and succeedingly transmitting a disconnection message so as to restore the disconnection. SOLUTION: When a terminal receiving a call setup message including user- user information(UUI) from a center via a network discriminates the call to be its own incoming call on the basis of a caller number, a caller sub address or contents of the UUI or the like described in the SETUP information, the terminal transmits a call massage (ALERT) to the center and then transmits a disconnection message (DISC) to the network. The called terminal receives a release message (REL) from the network and transmits a release completion message (REL COMP) to the network and is restored a standby state. Since the terminal receiving an incoming call transmits the ALERT to the center immediately after confirming the validity of the incoming call, the center can confirm that the terminal receives the UUI.

摘要： PROBLEM TO BE SOLVED: To obtain an ISDN communication system capable of continuously performing call out and reception to a specific center slave unit at a terminal in a center, having plural slave units utilizing UUI(user-user information) communication. SOLUTION: When a center 3, having plural lines is called from a terminal side, an NCU 9-1 of the terminal side first calls with a main telephone number A of a center 3 (step 200 and step 201), and a main selection device 5 of a center 3 side makes a center slave unit other than a center master unit 3-1, e.g. a center slave unit 3-2 receive (step 202). The receiving unit 3-2 attaches calling telephone number information, to which the telephone number B of the unit 3-2 is set to a UUI(user-user information) packet and answers the terminal side with it (step 210 to step 212). After that, the terminal side performs UUI(user-user information) communication with the calling telephone number B (step 220 to step 222).

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 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.
