摘要： A public switched telephone network (PSTN) provides communication of digital data from a data provider or LAN to one or more of a plurality of subscriber premises. Asymmetrical digital subscriber line interface units operating at variable rates and in variable modes (ADSL/AVRs) over a local loop offer one-way video-on-demand and other services and carry the necessary signalling between the subscribers and information providers. In an asymmetric mode, the interface units frequency multiplex digital information with voice information to the subscriber and support transmission of a reverse control channel from the subscriber to the central office for transmission back to the information provider. Other modes are supported which permit selective bi-directional and reversible communications as well.

摘要： A broadcast system supplies multiplexed channels to a plurality of receiving systems. The broadcast system preferably comprises a wireless digital simulcasting network. Each multiplexed channel carries multiplexed digital information signals relating to a group of programs. At least one of the receiving systems serves a plurality of living units. The multi-unit receiving system includes common equipment to perform as much of the processing of the digital information signals as is practical for the particular installation. The common equipment includes a digital receiver processing each multiplexed channel to capture a digital transport stream therefrom and a demultiplexer for separating out the digital information signals for each program from each digital transport stream. A switch routes selected information signals to individual drops or loops going to the living units. In one implementation, each digital information signal is modulated, and selected modulated signals are routed and transported over telephone wiring to terminals in the living units. The terminals demodulate and decode selected program signals for presentation on a television. In a second implementation, a decoder in the common equipment decodes each digital information signal, and the common equipment transmits an analog television channel carrying decoded signals for selected programs over coaxial cables to the living units. In this implementation, the added equipment required in a living unit includes only a remote control, an infrared receiver and a data device to transmit program request messages over coaxial cable to the common equipment.

摘要： Public communication networks increasingly need to provide customers with a range of communication services, from baseband voice service, to computer data communications, to high speed digital data communications for multimedia and the like. Many such services would be blocked by existing telephone network line cards, which provide coding and decoding (CODEC) between analog and digital signals and process digital signals only at a relatively low, fixed bit rate. In accord with the invention, intelligent signal detection and control added to a line card selectively bypasses the CODEC and the associated connection to a time slot limited telephone exchange. The selective bypass connection provides a connection to an alternative network functionality capable of providing higher bandwidth digital services. In the preferred embodiment, the bypass provides a connection through an adaptive digital signal processor with a programmed controller. The digital signal processor provides coding and decoding functions, adapted to the particular communication service requested and the physical level signal protocol used over the customer's line. The digital signal processor also provides a two-way digital communication link to a relatively fast data switch, such as an edge device of an asynchronous transport mode (ATM) network. The data switch and associated data network provide a full range of digital communication services of various bandwidths or bit rates as may be requested by individual.

摘要： An access subnetwork provides broadcast access transport as well as selective allocation of resources for interactive communications sessions dedicated to individual end users. The access subnetwork has specified broadcast and interactive service interfaces, both for communications to and from an information provider and for communication to and from customer premises equipment. An Access Subnetwork Controller provides a single point of control contact within the access subnetwork. Any other subnetwork (typically an element of a higher level control subnetwork) needing a control function in the access subnetwork always sends the request for that function to the Access Subnetwork Controller. The primary responsibility of the Access Subnetwork Controller is to control resources, provide requested resources and monitor the use of resources within in the realm of the access subnetwork. The Access Subnetwork Controller functions essentially in a similar manner to provide every type of requested connection, whether the connection is for broadcast, pay-per-view or Interactive Multimedia Television (IMTV). Specifically, the Access Subnetwork Controller reserves and enables access subnetwork resources for a particular user connection and reports connections back to higher level control elements.

摘要： In advanced digital networks for providing selective point-to-point communications between subscriber's terminals and broadband server's equipment operated by a plurality of independent information service providers, routing through the network is controlled by functionality identified as a Level 1 Gateway. In an enhanced video dial tone network additionally providing an array of broadcast services from multiple providers, the Level 1 Gateway also provides high level control over at least some of the broadcast services. The Level 1 Gateway will perform a variety of functions including communications port management of transmissions of information between subscribers and servers, processing of billing information and session management. The Level 1 Gateway generates menus of providers and broadcast services, either as a function of providers and services available through a particular portion of the network or in a customized fashion specified by individual subscribers. The Level 1 Gateway may also provide a PIN number functionality. The Level 1 Gateway is itself an interactive device in that subscribers can input information and receive display information from the Gateway to define or modify their own video dial tone service through the network.

摘要： An automated service level manager (SLM) provides operations support for wide-area data communication services offered via regional IP-Over Ethernet on fiber networks. The SLM comprises a suite of software components and associated hardware running the software, to communicate with agents throughout the networks, to accumulate various network operations data for reports and alarms and to provide instructions to control network operations. The SLM preferably offers a web server type user interface. This interface enables access by technical personnel of the carrier, for example from a network operations center. This interface also offers access to customers having or seeking service through the network.

摘要： An arrangement (apparatus and method) for obtaining a single copy of a received signal from a simulcast broadcast area. Within a desired service area, multiple transmitters at separately located sites simultaneously broadcast the same multi-channel, multi-program signal. Broadcast waves from the transmitters propagate throughout substantially overlapping portions of the service area. Each such channel carries a multiplexed digital data stream containing packets of information for a plurality of programs, e.g. television programs. A receiver system comprises an antenna adapted to receive direct transmissions from two or more of the transmitters as well as multipath signals from two or more of the transmitters. To compensate for the potentially interfering signal receptions, the terminal device includes a delay processor, such as an adaptive delay equalizer or a rake receiver. The maximum delay processing window of the delay processor is at least as long as the difference in propagation time to the receiver from two of the transmitters and preferably exceeds that time by some amount chosen to permit processing of multipath delay signals from the more distant transmitter.
