摘要： In an optical fiber telecommunications network for providing both narrowband telephony signals and broadband video services over a single optical fiber using a single optical carrier, an optical distribution shelf includes a plurality of optical distribution units and interface units for interfacing with a controlling microprocessor. The optical distribution units receive baseband TDM telephony signals in serial format and the broadband video signals and function to frequency division multiplex the broadband video signals with the baseband telephony signals. The multiplexed signal is used to frequency modulate an optical carrier for transmission on a single optical fiber.

摘要： An xDSL (x-Digital Subscriber Line) signal is multiplexed with POTS on a twisted pair between a subscriber modem and line termination equipment in a shelf that also includes network termination equipment for connection to a broadband network. The line termination and network termination equipment are interconnected by a bus internal to the shelf for providing subscriber access. Separate lowpass filters are provided at each end of a twisted wire pair between the shelf and each subscriber equipment. A shelf can be used as a hub for connecting to a remote shelf that includes the line termination equipment for connection to subscribers.

摘要： In an optical fiber telecommunications network, an optical network unit is provided in the subscriber neighborhood for terminating the optical fiber transmission line and for providing electrical signals over metallic lines to the subscribers. The unit functions to convert the optical signal to an electrical signal and demultiplex the electrical signal to divide out baseband telephony signals from broadband video channels. The electrical signals are further demultiplexed and distributed to line cards serving each subscriber, while the broadband video channels are demultiplexed and provided to subscribers that have requested specific video channels. The system includes a test unit for performing metallic tests and also a means to gather subscriber channel requests to form a video control channel which is transmitted to a remote terminal via a baseband telephony channel.

摘要： In an integrated telecommunications network adapted to provide narrowband telephony signals and broadband switched video signals, control signals for the broadband video signals are transmitted in the narrowband as baseband signals, which are frequency division multiplexed with the broadband switched video signals. The video control signals are transmitted over the same transmission lines as the broadband video signals and do not require the installation of additional transmission lines. Control signals from a plurality of subscribers are multiplexed together at a network unit and are transmitted as a channel on an optical fiber, after which the channels from a plurality of network units are further multiplexed together to form a frame of control channels which are transmitted to a video controller unit.

摘要： A terminal for a telecommunications system provides access to one or two high-speed synchronous transmission lines by both low-speed transmission lines and subscriber lines. A core module includes interfaces to the high-speed lines, a time slot interchanger, an interface to the low-speed transmission lines, processors and overhead circuitry for supporting the terminal. An access module includes a plurality of line shelves connected to subscriber lines, each line shelf includes a pair of processors and for time slot assignors. A multi-link serial bus connects the time slot interchanger to the access module and to the low-speed interface and provides close coupling between the processors in the core module and the line shelves. The processors cooperate to groom subscriber information from said subscriber lines to and from time slots in said high-speed feeder line and said low-speed transmission line. Subscriber information may also be groomed between time slots of the high-speed feeder line and the low-speed transmission lines and between time slots within each subscriber line.

摘要： A parallel time slot interchanger, particularly for use in telecommunication switching, comprises a plurality of switch groups, with each switch group containing a second plurality of channels. The parallel time slot interchanger incroporated a matrix-type architecture, with each module of the matrix comprising a switch block which in turn incorporates a switch memory, connect memory and associated control circuitry. The connect memory of each switch block is controlled by the control circuitry of that block. The data stored in the connect memory contains switch memory address information for reading channel data stored within the switch memory of the same switch block so as to be able to perform a time slot switching function during any given time slot of the parallel time slot interchanger. Each switch block is uniquely identified within its corresponding switch group so that only one switch memory address location is read and output during any time slot for each switch group.

摘要： An elastic storage circuit employs a first in/first out (FIFO) memory which stores data contained in a serial stream in a plurality of locations, each of which is associated with a unique address. The storage locations operate to store both the data and the address. A word address counter generates a five bit address code to accompany the data bits as stored in the FIFO. If a chronic increase or decrease in the frequency rate of the data occurs, the FIFO will overflow or underflow. This condition is detected by suitable detectors which create an alarm to completely reset the entire contents of the memory and to refill a portion of the memory over a given interval sufficient to permit the system to recover from the slip in the data rate and to thereafter synchronously read the data together with the address identification from the FIFO.

摘要： A three-ported apparatus is adapted to interface a serial TDM bus, a local controller and a line unit bus in a telecommunications terminal. All data passing between the TDM bus and the line unit bus is temporarily stored and is accessible to the local controller, allowing the controller to either pass said data without modification or provide modifications thereto. Signaling contained within the data may be translated to a form usable by the line unit through the use of translation tables down-loaded from inventory storage on the line units. For each line unit, the local controller programmably controls time slot assignment, provisioning and inventory information access.

摘要： In an optical fiber telecommunication transmission system, a remote terminal interfaces a high-rate optical fiber feeder line and a plurality of lower rate optical fiber distribution lines. The remote terminal includes a plurality of interfacing and signal cross-connecting devices which interface and cross-connect lower rate telephony signals with higher rate telephony signals. The plurality of interfacing and cross-connecting devices are interconnected with high-rate transmission lines so that telephony signals from under-utilized optical fiber distribution lines may be concentrated onto the high-rate optical fiber feeder line for efficient use of the feeder line.
