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： In fiber telecommunications network where an optical fiber is extended to the subscriber's neighborhood, mechanized loop testing is performed by a test unit located in a network unit in the subscriber's neighborhood. The test unit is responsive to commands from a controller located in the network unit to perform metallic line tests on the lines extending to the subscriber. Test results are stored in a memory associated with the controller in the network unit. Upon receipt of a test request from a central test controller, the controller within the network unit determines if there is sufficient time to perform the test; if so, a new test is performed and the results are conveyed back to the central test controller controller. If sufficient time is not available, the results of the last performed routine test contained in the memory are transmitted back to the central test controller. The test results sent back to the central test controller are conveyed firstly in the form of a particular four-digit code, which code is interpreted at a remote terminal and converted to a specific resistive signature which is conveyed back to the central test controller. The specific resistive signature is interpreted by the standard remote measurement unit located in a remote terminal.

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.

摘要： A line unit interface circuit used on line units in a line shelf of a digital loop carrier provides all of the logic necessary to access two subscriber lines to a line unit interface bus connected to common equipment within the line shelf. Information received from the common equipment includes signaling data, configuration data and provisioning data, which is reconfigured and processed by the line unit interface circuit for controlling the subscriber line channels. Configuration data from the common equipment is decoded to assign time slots on the line unit interface bus to the various channels serviced by the line shelf and to further provide for a timing offset between the transmit and receive strobes provided to each subscriber line circuit. A flywheel circuit is used to prevent erroneous time slot assignment in the event of noise or interference on the line unit interface bus.

摘要： A digital debouncing and storage apparatus operates on the receiving end of a digital carrier span line used in a telephony system to couple a multiplex signal to a receiving site to be used by the switching network control. Incoming signaling bits of the multiplex signal are stored in a random access memory at a particular storage location reserved for each channel contained in a group. There is also stored at the location previous timing information concerning each sampling bit. The circuit operates to time any change in the value of a status bit to insure that it lasts long enough to indicate a valid change of state. An up/down counter serves to time each status bit during predetermined signaling frames based on a count inserted into the counter indicative of the timing information as stored in memory. Thus each channel associated with the multiplex signal has stored in memory a unique status bit as well as timing information pertinent to that bit. The circuit operates over a predetermined number of frames whereby if the status of the bit has changed between one binary value to another, the circuit will recognize such a change only after a given number of signaling frames have elapsed. In this manner, contact bounce or channel interference which may effect the signaling bit is eliminated from interferring with system operation.

摘要： Various aspects of apparatuses and methods for enabling a subscriber premise network interface device (NID) to facilitate communication services including digitally derived voice services to be facilitated between a central office and a subscriber premise are disclosed herein. In accordance with one embodiment of the disclosures herein, such a method includes facilitating a downstream DSL voice channel transmission process at a subscriber premise Network Interface Device (NID) and facilitating an upstream DSL voice channel transmission process at the subscriber premise NID. The downstream DSL voice channel transmission process facilitates converting a voice component of a downstream DSL data stream to a corresponding downstream analog voice signal. The upstream DSL voice channel transmission process facilitates converting an upstream analog voice signal to an upstream voice component of an upstream DSL data stream.

摘要： An architecture, as well as various components, of an asynchronous transfer mode (ATM) subscriber access multiplexer (ASAM) system can be implemented using an XDSL (x-Digital Subscriber Line) using DMT (Discrete Multitone) or CAP (Carrierless Amplitude Phase Modulation) between a plurality of subscribers and a corresponding plurality of line termination equipment in a shelf that also includes network termination equipment for connection to an ATM 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. Although the internal bus of the shelf is shown in a non-redundant embodiment, an increased level of equipment protection can be provided by placing one half of a redundant equipment pair in one shelf and the other half in the other shelf and sharing network termination equipment between such shelves.
