摘要： PURPOSE:To attain high speed allocating processing of subscriber lines with one time switch by switching a B channel signal and a D channel collectively whose capacity, that is, whose transmission speed differs each other through same exchange processing. CONSTITUTION:A channel signal demultiplexer circuit 11 receives an incoming multiplex signal via highways 100-107 to demultiplex the signal into a B channel signal and a D channel signal. Then the B channel signal is converted into a parallel signal by an S/P conversion circuit 12, a D-channel signal is multiplexed by a multiplex conversion circuit 13 to be synchronized with a D channel signal corresponding to the B channel signal. Then both the signals are inputted to a time switch 14 and are subjected to parallel exchange processing altogether. Then the B channel signal is converted into a serial signal at a P/S conversion circuit 16 and the D channel signal is demultiplexed by a multiplexer/demultiplexer circuit 17. Then a channel signal overall circuit 18 receives both outputs to re-compose the original subscriber signal.

摘要： PURPOSE:To reduce the time and the labor of a maintenance engineer for solution of the factor of a trouble by converting automatically the trouble information into a programmed form of a load module and outputting this converted information. CONSTITUTION:A trouble information analysis back-up device 1 consists of a CPU 10 together with a keyboard 11, a memory 12, a display 13, a hard disk device HD 14, a line printer 15, a floppy disk FD 16, a magnetic tape device MT 17, and a communication device 18 which are all connected to the CPU 10. Then the trouble information is automatically converted into a form which is defined by a source program SP by reference to a compiling list CL and a linkage list LL related to a load module program LP included in the trouble information. Then this converted information is outputted. Thus it is possible to reduce the time and the labor of a maintenance engineer for solution of the factor of a trouble.

摘要： PURPOSE:To provide the system operating information management device restoring only the system operating information on a controlled device requiring restoration in a shortest path. CONSTITUTION:When a fault takes place in a 1st controlled device 11 or the occurrence of a fault in a 2nd controlled device is informed, the 1st controlled device 11 informs a central processing unit 10 of it. The central processing unit 10 informs the 1st controlled device 11 of a system operating information restoration request. When the fault takes place in the 1st controlled device 11, the 1st controlled device 11 reads the system operating information from the 2nd controlled device 12 to restore the system operating information of itself and when the fault takes place in the 2nd controlled device 12, the system operating information of the 1st controlled device 11 is transferred to the 2nd controlled device 12 to restore the system operating information of the 2nd controlled device 12.

摘要： PURPOSE:To efficiently store an analog or digital subscriber line signal and to easily shift a system from an analog subscriber to a digital subscriber by providing a virtual container multiplexing means and a control channel multiplexing means. CONSTITUTION:An optical subscriber line multiplex part 11a executes format conversion which is to efficiently store the analog (A) and digital (I) subscriber line signals from a subscriber interface device 21 and a digital subscriber line terminal station equipment 24 to an optical 156Mbps highway and to multiplex it and it converts the signal into an optical signal. On the other hand, a remote multiplex device 4 multiplexes the highway signal of 8Mbps from an A or I subscriber interface device 41 and gives it to a remote multiplex transmission device 31. The electric 8Mbps highway signal is converted into the optical highway signal, transmits it free from a distance, is transmitted to a 156Mbps interface line concentration channel device 156 or an adapter 71 through a line cross connection module 5. The optical 156Mbps highway signal is separated into 16 by the adapter 71, and they are given to a basic interface device 25.

摘要： PURPOSE:To allow the control circuit to make control so as not to malfunction at an output side on the occurrence of a fault in a transmission line by outputting specific information in a read timing in place of information read from a storage means when the fault is detected. CONSTITUTION:A clock/frame fault detection circuit 2 monitors a highway write clock WCK and a highway write frame WFP to discriminate whether or not they are in error. It is discriminated to be normal when no error takes place. A selection circuit 4 outputs output data from an elastic store memory ESM 1 when no error takes place. When the error takes place, the clock/frame fault detection circuit 2 generates an error signal, which is used for the notice to the selection circuit 4. Upon the receipt of the notice, the selection circuit 4 outputs output data of a data generating circuit 3. Guaranteed data are generated in place of uncertain data outputted from the memory and they are sent as above.

摘要： PURPOSE:To shorten the time required for restarting an operation of an information processing system by an emergency control operation by designating a converting means for making an output effective, based on a counting value outputted from a counting means, by a selecting means. CONSTITUTION:A counting means 100 counts the number of times by which a central controller 1 tries to restore the storage contents of a main storage device 2 by the storage contents of a present file 4a and each past file 4b-4n which have been stored in a file storage device 4. Also, each converting means 200 converts an address aa which the central controller 1 sends out in order to execute an access to the present file 4a, to addresses ab-an which are brought to access to the respective corresponding past files 4b-4n and outputs them. Subsequently, a selecting means 300 designates the converting means 200 for making an output effective, based on a counting value outputted from the counting means 100. In such a way, even if the central controller 1 always outputs a specific address to the file storage device 4, the restoration can be executed by a different past file without executing a copy, and the time required for restarting an operation of an information processing system is shortened.
