摘要： PURPOSE:To provide the system switching control system for duplex transmitter provided with system switching control parts at respective line corresponding parts. CONSTITUTION:When a transmission line is operated in a normal state, a system switching control part 21a-1 of a line corresponding part 2a-1 on the standby state side is turned to an operating state, a system switching control part 21b-1 on the active state side is turned to a non-operating state and when the transmission line is completely recovered, the operation modes of two system switching control parts are switched. Thus, the operating state of the system switching control part can be easily controlled, and the man-hour of development can be reduced.

摘要： PURPOSE:To reduce the number of cables by accommodating a 1st selector mounting printed circuit board in a same nuit as a printed circuit board with a line correspondence section mounted thereon. CONSTITUTION:Signals from line correspondence sections 100-107, 110-117 are outputted to switch sections 200, 210 and signals from the line correspondence sections 100-107, 110-117 are outputted to inter-link sections 300, 310 by using a back wiring board printed wire of the line correspondence section 100 because the printed circuit board with the inter-link sections 300, 310 mounted thereon is accommodated in the line correspondence unit 00. Thus, when the output of signals from the line correspondence sections 100-107, 110-117 to the switch sections 200, 210 is executed by using a BWB printed wiring, one cable per one half system is enough to connect the units 00, 10 to output a speech signal from the inter-link sections 300, 310 to the switch sections 200, 210. Thus, the hardware quantity of the inter-link section connecting 0, 1 system of the line correspondence section is reduced.

摘要： PROBLEM TO BE SOLVED: To prevent increase in a load of network processing due to mis- discrimination of an ATM connection state caused by the effect of production of a physical layer fault and due to a notice processing undesired attended with a transmission line fault restored immediately in the fault monitor of the ATM connection with respect to an OAM(operation and maintenance) function in the ATM(asynchronous transmission mode) exchange technology. SOLUTION: This processor 100 monitors an arrival state of an alarm cell as to each ATM connection and discriminates an ATM connection receiving an alarm cell at a time interval within a prescribed time to be an alarm state and an ATM connection not receiving an alarm cell over a prescribed time to be a normal state based on the result of monitor. When a fault of a physical layer with respect to the ATM connection discriminated to be in an alarm state is detected, the ATM connection is discriminated to be in an alarm state regardless of the result of a monitor till the fault is recovered.

摘要： PURPOSE:To obtain the facsimile reception notifying equipment used to notify that the reception of facsimile information is finished to a called party. CONSTITUTION:When facsimile communication between a caller facsimile equipment 1 and a called facsimile equipment 4 is finished, a called side exchange 3 starts the facsimile reception notifying equipment 6. The facsimile reception notifying equipment 6 retrieves the number of a telephone set corresponding to the called facsimile equipment 4 among the number of telephone sets 5 stored in advance and sends a call request to the retrieved telephone set 5. When the telephone set replies, an audible tone representing the end of reception of the facsimile information is generated. Thus, the end of reception of the facsimile information is noticed to the called party even in a existing facsimile equipment by having only to install the facsimile reception notifying equipment.

摘要： PROBLEM TO BE SOLVED: To provide packet communication equipment with a no-hit line function by which neither error nor less of user information is generated even if a line failure occurs, a packet communication network and its method for switching lines in asynchronous communication network with simple structure. SOLUTION: Transmission packet communication equipment is constituted so that a marked packet is inserted and transmitted in packet a flow with prescribed cycles and inserts error check information of user packets between marked packets and packet identification information of the packets into the marked packet. Receiving packet communication equipment performs phase management and error detection of the packets asynchronously received from information about the received marked packets, switches and outputs an original packet flow of a normal line by a plurality of packet units included between the marked packets by using the marked packets. The packet communication network transmits/receives the marked packets including error detection information and the identification information of a plurality of the marked packets by a plurality of the units and switches the lines by using the marked packets.

摘要： PURPOSE:To perform fault processing with a fault processor provided with the small kinds of softwares by separating the fault processing into fault processing not depending on the hardware and fault processing depending on the hardware. CONSTITUTION:Computer units 11-13 are provided with means at firmware parts 21-23 so as to prepare fault report information while distinguishing it into the two kinds of first fault report information 31 to transmit a recovery enable fault by exchanging the hardware and second fault report information 32 to transmit a recovery disable fault by exchanging the hardware. A fault processor 7 is provided with a means at a CPU 10 so as to first process the first fault report information 31 and to process the second fault report information 32 later when the fault can not be recovered. Thus, the kinds of memory means for storing the fault processing softwares and the fault processing softwares can be reduced, and countermeasures at the time of generating the fault can be speedily executed.
