摘要： Modular multiplex/demultiplex apparatus suitable for use in a telephone communication system for processing data transmitted between local and remote telephone subscribers. The multiplex/demultiplex apparatus comprises a plurality of module units which may be interconnected together, for example, in one or more groups, for processing and routing data originating with local subscriber equipment to selected ones of a plurality of trunk group modules and associated modems for transmission to remote subscriber equipment, and for processing and routing data received by the trunk group modules and modems from remote subscriber equipment. Each module unit includes a shift register having a plurality of demultiplex input lines for receiving demultiplexed data thereon and a series input for receiving multiplexed data. Data present on the demultiplex input lines or at the series input is shifted to an output of the shift register. The module unit further includes a plurality of multiplex output lines and associated gates connected to the multiplex output lines and in common to the output of the shift register. One of the multiplex output lines represents a module interconnection line and is connected to the series input of the shift register of an adjacent module unit. Data shifted to the output of the shift register is selectively gated through one of the gates to either the multiplex output line connected to the series input of the shift register of the adjacent module unit or to one of the other multiplex output lines to an associated trunk group module and modem.

摘要： Modular multiplex/demultiplex apparatus suitable for use in a telephone communication system for processing data transmitted between local and remote telephone subscribers. The multiplex/demultiplex apparatus comprises a plurality of module units which may be interconnected together, for example, in one or more groups, for processing and routing data originating with local subscriber equipment to selected ones of a plurality of trunk group modules and associated modems for transmission to remote subscriber equipment, and for processing and routing data received by the trunk group modules and modems from remote subscriber equipment. Each module unit includes a shift register for receiving and shifting therealong a multiplexed signal received from a selected one of the trunk group modules. A counter counts the bits shifted along the shift register and when the shift register is full it produces an output count signal. A counter logic circuit of the module unit operates in response to an output count signal to respectively produce and apply a transfer signal and a full signal to a first latch register coupled to the shift register and to the counter logic circuit of the next module unit in the series. The transfer signal causes the latch register to receive the data from the shift register following which the data is further processed and read out to a plurality of demultiplex output lines. A counter logic circuit receiving a full output signal operates to produce a transfer signal and full output signal for use in the same manner as discussed above.

摘要： A TDM switching network for a communication system having 17 input transmission lines for carrying TDM digital signals in 64 input channels on each input line and having 15 output transmission lines for carrying TDM digital signals in 64 output channels on each output line. The TDM switching network establishes connections between selected input and output channels in accordance with address instructions having A and B address segments each designating a particular channel of a particular transmission line. The switching network includes 15 switching matrices (plus a spare). Each matrix is connected to all 17 of the input transmission lines and to a different one of the output transmission lines. Each switching matrix includes a data memory which can store a data bit for each channel of each transmission line. Each matrix also includes an address memory which can store an address segment for each channel of the associated output transmission line at a corresponding storage location. An address instruction is transmitted to all the switching matrices and comparisons are made by each matrix to determine if the transmission line designated by either address segment designates the output transmission line associated with the matrix. The matrix having the output line designated by the A address segment loads the B address segment in its address memory in the storage location corresponding to the channel designated by the A address segment. Similarly, the A address segment is placed in the matrix and at the storage location corresponding to the transmission line and channel designated by the B address segment. The storage locations of an address memory are read out in sequence by corresponding channels. If an address segment is read out of the address memory, the data bit designated thereby is selected from the data memory and applied to the output transmission line of the matrix in the channel corresponding to the storage location the address segment occupies in the address memory.

摘要： An essential user bypass circuit for use in switch units of a telephone switching system. Telephone subscribers at each switch unit are able to communicate with each other and with subscribers at other switch units via associated subscriber apparatus and trunk group lines interconnecting the switch units. All call processing operations, including the formation of "from-to" address signals for connecting subscribers with each other and with trunk group lines, are normally controlled by a processor unit (containing dual processors) at each switch unit. In the event of malfunction or failure of a processor unit or of certain other associated subscriber hardware, an essential user bypass circuit may be actuated in accordance with the invention, for example, by a manual switch, to bypass the malfunctioning or failed equipment to allow certain ones of the original subscribers, for example, ten percent of the original subscribers at the switch unit, to be connected with trunk group lines thereby to maintain communication with subscribers at other switch units. The connection of subscribers with trunk group lines is accomplished by the prestorage of a limited number of "from-to" address signals therein which are like those normally produced by the processor unit and which may be applied to the subscriber apparatus upon the malfunction or failure of equipment to cause the subscriber apparatus to establish the particular connections specified by the address signals.

摘要： Digital signal generator for producing digital signalling codes employed in a digital telephone communication system including several tone generators for providing presynthesized digital tone signals which are convertible to audible tones. Permutable digital codewords are produced by a codeword generator. Some of the tone signals and codewords are combined by FSK and switching circuitry. Tone signals, codeword signals, and combination signals are stored in storage registers and read out by a multiplexer to provide a continuous TDM bit stream of 60 channels of digital signalling codes.
