摘要： A digital cross connect comprises plural switching stages. Each stage has plural switches which receive plural frames of time multiplexed input data and which switch the data in time and space. Configurations of the switches change in frame synchronization at the start of a synchronized data frame. Both the configuration data and a frame clock may be propagated through the plural stages from a master switch. First and last stages of the digital cross connect may be implemented on common chips having two framing time bases. Data may be aligned to a global frame clock and interchanged using a single random access memory in a time slot interchanger. The write address to the random access memory is generated from a local frame counter keyed to the input data frame while a read address is transformed from a global frame counter.

摘要： A system for automating cross connections in an access network. The automated cross connect system comprises of a plurality of upstream line interface circuits adapted for connection to upstream communication links, and a plurality of downstream line interface circuits adapted for connection to downstream communication links. The upstream and downstream line interface circuits are interconnected by an automated cross connect switch that selectively couples particular upstream line interface circuits to particular downstream line interface circuits, in response to routing commands sent from a command center. Thus, the automated cross connect system selectively establishes a bi-directional communication path between the upstream line interface circuits and the downstream line interface circuits, thereby providing a communication path between a selected upstream communication link and downstream communication link. The automated cross connect switch may be implemented in either a space or time multiplexing devices, such as a physical layer router, which comprises an array of cross connected multiplexers, or a time domain multiplexer switch, which composes an array of serializers connected to a time division multiplexed bus.

摘要： Communication circuitry is comprised of processing circuitry, parallel channels, and crossbar integrated circuits. The processing circuitry exchanges the communications between communication links and the parallel channels. The parallel channels transfer the communications in parallel with a clock signal. The crossbar integrated circuits receive the communications and the clock signal over the parallel channels, switch the communications based on the clock signal, and transfer the switched communications to the parallel channels.

摘要： In an audio-digital telephone interface system, selective operation prompts a caller with oral instructions to provide: digital control signals, digital data signals (numeric) or audio signals. Inbound and outbound operations are involved and inbound callers are qualified as by automatic number identification (ANI) signals and consumable key operation. A data cell is loaded in accordance with an operating program and the resulting data packet is flagged depending on the presence of audio signals. Data packets are returned to storage, as for subsequent addressing to call up, as to process or cue a caller. The illustrative format receives and organizes order data for goods or services or to isolate a subset or a sub-subset of callers.

摘要： Methods and apparatus are described relating to a system-on-a-chip which includes a plurality of synchronous modules, each synchronous module having an associated clock domain characterized by a data rate, the data rates comprising a plurality of different data rates. The system-on-a-chip also includes a plurality of clock domain converters. Each clock domain converter is coupled to a corresponding one of the synchronous modules, and is operable to convert data between the clock domain of the corresponding synchronous module and an asynchronous domain characterized by transmission of data according to an asynchronous handshake protocol. An asynchronous crossbar is coupled to the plurality of clock domain converters, and is operable in the asynchronous domain to implement a first-in-first-out (FIFO) channel between any two of the clock domain converters, thereby facilitating communication between any two of the synchronous modules.

摘要： A multi-stage clock distribution scheme for use in a signaling server organized into a plurality of uniquely addressable shelves. The signaling server includes a system timing generator, one or more clock distribution modules arranged in a nested hierarchical manner, and a plurality of bus control modules, wherein each bus control module interfaces with at least a portion of line cards disposed in a shelf. The system timing generator provides a framed serial control signal, SFI, for controlling the operation of the multi-stage clock distribution scheme. The SFI signal encodes the IDs of the clock distribution modules and bus control modules whereby a system clock generated by the system timing generator based on a select reference input is successively fanned-out by the intermediate clock distribution modules based on address and ID information encoded in select fields of the SFI frames until the fanned-out system clocks are received by the bus control modules. Thereafter, each bus control module provides a copy of the system clock to the line cards controlled by it based on the SFI signal.
