摘要： A packet data switching system having packet switching equipment and a plurality of transfer control units cooperating with the packet switching equipment exchanging packet data to be transferred through the transfer control units. In the system each packet data is divided into packet frames each having the same frame length and all the packet frames are processed synchronously in each of the transfer control units. Each of the packet frames is composed of a header area and data area. The header area is used for indicating transfer control information, such as an address of a destination transfer control unit and a continuous transmission flag which denotes that the related packet frame should be exchanged to the same destination as that of the preceding packet frame.

摘要： A packet data and a header added to a head of the packet data for specifying a transfer condition of the packet data are divided together to data blocks (DBs) each having a designated data length, consisting of an initial DB including the header and an initial part of the packet data, intermediate DBs each including an intermediate part of the packet data and a last DB including a last part of the packet data, so as to be transferred to a data transfer destination in a data processor of a switching system in accordance with write commands for the initial, intermediate and last DBs respectively, and a read command for asking whether the DBs are correctly transferred is sent to the data transfer destination once, after the DBs are transferred. When the DBs are transferred, the packet data is restored at the data transfer destination only by synthesizing the transferred DBs and removing the header.

摘要： An ATM switch system performs a DMA (direct memory access) transfer of a command and status data between a call processor and a processor of a communications control device via a peripheral interface. An inter-processor DMA transfer controller of the communications control device controls a DMA transfer between its memory and the main memory of a call processor for expediting communications between the two processors.

摘要： A boot program which can independently set the signaling links with the exchange is stored in the memory of a line concentration group. Under this boot program, a signaling controller (SGC) is used to set up a signaling link from the line concentrator to the exchange. Through the signaling link, a call processing program is transferred from the exchange side to the line concentrator side, and the transferred call processing program is used to start up the line processor in the line concentration group.

摘要： A subscriber line control device utilizes a scan input table and a last look table. The scan input table stores respective current line states of a plurality of analog subscriber lines. The last look table stores respective preceding line states of the plurality of analog subscriber lines and information for validating or invalidating a timer device. A valid timer device corresponds to when a monitoring process is required. The scan input table is compared with the last look table at every predetermined cycle. When they do not match, it is judged whether the line state has changed or if the timer device is validated. Based on the judging result, an analog subscriber line control is performed according to an instruction specified by a call processing unit. The analog subscriber control is any of a call origination monitor, a dial pulse monitor, and an on-hook and off-hook (HIT) monitor.

摘要： A message division communication method and system are disclosed for a communication system comprising a host, an intermediate device connected to the host through a high-speed bus and a remote device connected to the intermediate device or the host through a low-speed bus. A message is transmitted in such a manner that the host designates and notifies the remote device of a maximum message length determined in a way corresponding to the transmission rate of the low-speed bus and divides the message into division messages each not exceeding the maximum message length thereby to transmit and receive the division messages between the host and the remote device. Even with a communication system in which low-speed and high-speed buses coexist, a message can be transmitted and received by a common communication control scheme.

摘要： In a path audit control method, (1) a unit (a discrete unit or common unit) within a switch holds bitmap information indicating whether each channel identifier is being used to establish a path; (2) a central controller sends the unit bitmap information indicating whether each channel identifier has been used to establish a path; (3) the unit compares bitmap information which it itself is holding with bitmap information that has been sent from the central controller; and (4) if the bitmap information held by the unit and the bitmap information that has been sent from the central controller do not match, the central controller and the unit cooperate to execute matching processing in such a manner that the compared items of bitmap information will be made to match.

摘要： An RS232C driver inside target firmware controls an RS232C interface. An OS debugger steals an input to and an output from another function block that is the actual target firmware, and exchanges that input and output with the RS232C driver 1005. This configuration makes it possible to easily connect a device that executes the target firmware to, for example, a personal computer, using a general purpose RS232C interface, and makes it possible to easily obtain debugging operation using the PC side debugger.
