摘要： This invention relates to a time division switching system for exchanging audio signals, data and so on in a time division manner. This time division switchboard comprises a plurality of separate local exchange units capable of interfacing with various different circuits such as subscriber lines, trunk lines, service circuits and so on, one or a plurality of junctor high ways connected to a time switch of each of the local exchange units, and one or a plurality of tandem exchange units each having a time switch connected to the other ends of the junctor high ways and switching by the time switch. Each of the local exchange units selects a channel on an arbitrary junctor high way and transmits control information concerning other one of the local exchange units to which a calling is to be sent, to one of the tandem exchange units which has the selected junctor high way connected thereto. The tandem exchange unit to which the control information is sent selects a channel on a junctor high way connected to the local exchange unit to which the call is to be sent, in response to the control information sent thereto, thereby switching the calling to the desired local exchange unit. Thus, since the respective units can be loosely coupled to each other, the time division switching system of this invention has high reliability and good economy.

摘要： A time-division switching unit for connecting a desired channel of a desired one of a plurality of input highways to a desired channel of a desired one of a plurality of output highways is disclosed. A frame synchronization circuit of the time-division switching unit variably delays signals of the input highways within one channel period, writes the signals to a speech memory for each channel, modifies write addresses to the speech memory to attain frame synchronization, extracts frame synchronization signals of the respective highways from the input and output of the speech memory, and controls the amount of delay within one channel period and the amount of address modification by the extracted synchronization signals.

摘要： An I/O prescription table (I/O PTBL) is associated with a processing program module that is executed by a conventional sequential execution type processor. Each processing program module fetches the input data according to its associated I/O PTBL and stores the output data in the same table. An execution control program makes reference to the I/O PTBL associated with the processing program module, updates the designated I/O PTBL so as to indicate that the corresponding input data is prepared, and starts the processing program module associated with the I/O PTBL which is furnished with all of the necessary input data.

摘要： A high-speed ring LAN capable of accommodating at least one public network having a signal transmission rate of 155.57 MHz, and at least one sub-LAN having a signal transmission rate of 100 MHz. The high-speed LAN has a signal transmission rate of 155.52 Mbps .times.n (n is an even number). SONET (Synchronous Optical NETwork) subframes each comprising a 9 bytes .times.9 section overhead area and a 261 bytes .times.9 virtual container 4 (VC-4) area flow in a time-divisional n-multiplexed format. The respective node devices inserted in the transmission path have one or more ports to accommodate sub-LANs or public networks. Information is exchanged in units of a fixed-length packet between a received SONET subframe and an asynchronous port whereas information is exchanged in units of a byte between the SONET subframe and a synchronous port.
