摘要： PURPOSE:To provide a communication processing unit capable of processing a packet signal, a frame relay signal and an ATM cell. CONSTITUTION:The processing unit is provided with a fixed length cell interface section 12 receiving an ATM fixed length cell whose path is selected by using a VPI/VCI and a variable length frame interface section 13 receiving a variable length frame signal. The variable length frame interface section adds the VPI/ VCI to the variable length frame signal. A communication processing section 11 makes communication processing to both the ATM fixed length cell and the variable length frame signal based on the VPI/VCI. Since the processing unit processes a packet signal, a frame relay signal and an ATM cell in this way, the processing unit deals for a long time with the technological innovation.

摘要： PURPOSE:To obtain the communication system at a high speed with high flexibility and extension. CONSTITUTION:A non-use VC table 11 representing a VC not in use is provided in a transmission end 1, a VC not in use is retrieved from a table 11 in response to a transmission request, the VC is set as a VCI of an ATM cell and address information to specify a communication opposite party is added to the cell and the resulting cell is sent. An ATM switch 2 and a routing controller 3 decide routing from the sending end 1 to a receiving end 4 based on the address information in the cell and the decided routing content is stored in a routing table 31 in the controller 3. Data from the sending end 1 are received at the receiving end 4 based on the decided routing. Since the registration of a table is revised at a high speed with high flexibility because of independent of out- band signaling, high extension performance is attained.

摘要： PURPOSE:To attain accurate discrimination by extracting a name of a device raising an alarm at the highest position on the hierarchy from the standpoint of the network, a name of a device opposite to the name of the device raising the alarm in terms of logic and a name of the device connecting physically to the device raising the alarm and discriminating the fault based on three kinds of alarm signals as signal input interruption to and from a host and signal output interruption from a subordinate device. CONSTITUTION:Fault information generated by each device being components of a communication network is classified into three kinds as signal input interruption to and from a host and signal output interruption from a subordinate device based on the hierarchy of the network. A name of a device raising an alarm at the highest position on the hierarchy from the standpoint of the network, a name of a device opposite to the name of the device raising the alarm in terms of logic and a name of the device connecting physically to the device raising the alarm and discriminating the fault among faulty devices are extracted respectively and a fault location is specified according to the discrimination rule based on the fault information of the extracted device. The discrimination rule is stored in a storage means 800. Then a device going to raise an alarm affected by the fault is extracted based on the result of discrimination and the result of discrimination is verified by confirming the device raising actually the alarm among the devices.

摘要： PURPOSE:To perform write without being conscious of overflowing from a character frame and to prevent a recognition rate lowered by performing verification whether or not a character is overflown from the character frame when the character is segmented by using the character frame. CONSTITUTION:The absolute value ¦X(mt)-Xt¦ of difference between an X character frame boundary value (mt) and an X-axis signal Xt is found at an X approach judging part 14. A signal ZX=1 when the above value exceeds a value THm stored in an X constant storage part 15, and a signal ZX=0 when the former is less than the latter are outputted to an AND 16. The AND 16 takes the AND of the signals ZX and NX, and outputs a result to an OR 31. When the value shows 1, it means that X character frames approach with each other and they are separated from a boundary position, then, the segmentation of the character is performed. Also, the segmentation of the character is performed at a Y approach judging part 24 by applying similar judgement. The OR 31 takes the OR of a non-approach signal NC and the signals ZX, ZY, and outputs a segmentation signal C when either the signals goes to 1 and the segmentation of the character is shown. Adversely, when all the signals go to 0s, no segmention of the character is performed, and no segmentation signal C is outputted.

摘要： PURPOSE:To simplify band allocation control by inputting boundary information, which designate one band out of two channels, and comparing the counted values of first and second counters with the boundary information. CONSTITUTION:The conditions of a row counter 1 and a column counter 2 are expressed by (a row counter value, a column counter value) and the storing value of a register 3 is expressed by a (3, 1). A time slot to be allocated to a CH-A is given with (0, 0), (1, 0) [first string], (0, 1), (1, 1) [second string], (0, 2), (1, 2) [third string], (0, 3) and [fourth string]. In a comparator 4, this time slot is recognized as 00, 10, 01, 11, 02, 12 and 03 and compared with the value 31 of the register 3. When the values to be shown by the row counter 1 and column counter 2 are smaller than this value 31, the CH-A is set to be necessary and enough. Thus, the band allocation control can be simplified.

摘要： PURPOSE:To uniformly deal with the form of various networks with a single frame format by adding a function which designates not only the kind of service but also the constitution of the frame and the length of an address part to FID. CONSTITUTION:When there is the transmission request of ISDN service, a transmission control part 3 connects an LAPD processing circuit 2 to an MAC frame circuit 5 through a multiplex circuit 4. The MAC frame circuit 5 adds the address of ISDN23 as DA and its own address as SA, and FID showing ISDN service is added in a FID circuit 6. As a result, the packet in the constitution of a figure (b) is transmitted. As for LAN service, the address of the opposite terminal is set as DA in the MAC frame circuit 5, and FID showing LAN service is given in the FID circuit 6. The packet frame in the constitution shown in a figure (a) is transmitted.

摘要： PURPOSE:To realize the allocation of TEI without providing a new procedure by constituting that the allocation of the terminal identifier TEI for terminals and the generation of the collation table of the LAN-MAC address of the TEI of the terminals are executed through the use of the control procedure of TEI, which is specified in CCITT. CONSTITUTION:The terminals 2 and 3 are connected to LAN 1, and are further connected to a D channel handler 44 by an ISDN interface 4. A TEI control method in a network which executes packet communication by using the address allocated to the terminals and ISDN for destination information of the packet and originator information is that an LAPD data unit detects the reception packet being a TEI check response signal and generates the collation table of the address and TEI allocated to the terminals based on detected originator information of the reception packet and an action indicator in the LAPD data unit in the ISDN interface 4 which receives the packet from the terminals for the ISDN system.

摘要： PURPOSE:To remove a noise by processing a writing point detected at present as the noise when a writing point just after is detected only when both the distance between the writing point detected at present and the writing point detected just before and the distance between the writing point detected at present and a writing point detected just after exceed a prescribed value. CONSTITUTION:When an n+1 is inputted to a writing point storage circuits 3, if an (n) is already inputted to and stored in a writing point storage circuit 4 as a signal and an n-1 is already inputted to and stored in a writing point storage circuit 5 as a signal, an X coordinate value and a Y coordinate value are respectively led from the writing point storage circuits 5 and 4 into an X computing circuit 6 and a Y computing circuit 7 and respective differences of the X coordinate value and the Y coordinate value are computed separately. When neither of the respective differences of the X and Y coordinate values exceeds the noise decision reference value, a noise deciding circuit 14 transmits a decision that the coordinate value of the (n) is not due to the noise to a control circuit 15 and when either of the respective differences of the X and Y coordinate values exceeds the noise decision reference value, the noise deciding circuit 14 transmits a decision that the coordinate value of the (n) is due to the noise to the control circuit 15.
