A twisted pair and/or coaxial cable fed set-top device provides a plurality of services, including computerized directory assistance services and identification of the geographic location and set top device from which a directory assistance query has been made. Directory assistance information may be broadcast from a cable head end, or a directory assistance database may be searched, based on a query entered by a user, or both broadcasting and searching may be performed. The search results can be prioritized based on the geographical proximity between locations of the listings in the search results and the location from which the query was entered. The address of the set top device and/or the tap to which the set top device is coupled are used for determining the location from which the query was entered.

A system architecture for bypassing a local exchange carrier comprises an intelligent terminal, a residential gateway coupled to the terminal, a cable facility management platform terminating a twisted pair or coaxial cable facility and a network service platform. The platform serves both a cable headend and a telephone DSL network to enable a single service provider to provide different information content services independent of how a user actually receives the services. The twisted pair and/or coaxial cable fed, integrated residence gateway controlled intelligent terminal or set-top device provides a multiple menu heirarchy for selecting a plurality of enhanced services. The menus are implemented on a video telephone or similar device with a touch-sensitive screen display for interactively displaying video and accompanying audio signals and menu screens. The integrated residence gateway is coupled to either or both of the coaxial cable or twisted pair and distributes the bandwidth facilities available over either service vehicle to customer devices including the set top box.

A subscriber link to a central office which employs data compression, forward error correction, and advanced modulation techniques and to connect subscribers to multiple communications networks to provide an array of services. A device provides normal telephone service in the event of an equipment failure. At the subscriber end, a server called an intelligent services director (ISD) provides multiple independent connections for telephones which ordinarily connect to multiple access virtual circuits generated on the subscriber link over a twisted pair. A device called a facilities management platform (FMP) at the central office end of the link, among other things, provides interfacing of the subscriber link to various networks including a digital subscriber loop (DLC) and packet switched networks. Ordinarily telephones connected to the ISD require power and correctly functioning modems and controllers in the ISD and the FMP to have access to the outside world. A fail-safe mechanism, however allows at least one chosen phone to function in the event of a failure. The chosen phone must be capable of pulse or DTMF dialing. The connection through which it operate can be switched directly to the twisted pair media connecting to the FMP. At the FMP, the twisted pair is switched to tie the connection directly to a line card of the DLC. Alternatively, the ISD contains an interface to a specialized phone designed for the ISD environment. The interface provides the appearance to the DLC of a regular POT.
摘要:
A dynamic bandwidth allocation system is used to optimize the transmission of traffic on the twisted pair connecting the customer premises equipment with the local office. As demand for simultaneous traffic at the customer premises equipment increases, the requirement for multiple twisted pair lines is minimized by dynamically allocating the bandwidth of the channel and sharing that bandwidth with multiple, simultaneous services. Additional efficiencies for simultaneous transmission of traffic can be achieved by directing all traffic to occupy a smaller channel. This might slightly affect the quality of some services but in many cases the impact will be minimal. Voice signals will be allowed to decrease to a predetermined level and facsimile or other data traffic will transmit at a slower transmission rate. At some predetermined level, traffic quality will degrade to a level such that service will be unacceptable. At this point, a prioritization scheme will buffer certain traffic at the intelligent services director (terminal block) or the facilities management platform (access module). New requests for services are denied until the required bandwidth is free. Once the required bandwidth becomes available, buffered traffic is allowed to transmit or receive will flow again and service availability will resume. An alternative scheme employs allows all services to maintain their highest quality and ranks all traffic by a priority scheme. Once the allocated bandwidth is occupied, the priority scheme discontinues or buffers lower ranking traffic. Once bandwidth resources are released by the higher ranking traffic, the lower ranking traffic is allowed to proceed if the information was buffered. By optimizing the traffic on the twisted pair, requirements for the installation of multiple twisted pairs is minimized as services are added by the user.

A subscriber to a service will have the ability to order or request additional information on products that are being advertised. The service will have the ability to know which commercial is being aired in which subscriber initiated the request. The subscriber to the service upon viewing a commercial on a display terminal can click on the advertisement to alert the advertiser that the customer is interested in the item that is being advertised. Such interest may include, receiving an information pamphlet, receiving a coupon, and ordering the product directly from the manufacturer or distributor through a requisition request.

A railroad-crossing warning system for protecting pedestrians and motorists from an oncoming train. The warning system has a vehicle detector system for determining whether a vehicle is stuck in an area of the railroad crossing, a train detector system for determining vital train information including the speed and direction of the oncoming train, a display unit for displaying warning messages to the pedestrians and motorists approaching the railroad crossing, and a communication system for communicating the vital train information and the distressed vehicle information to the oncoming train and the display system. The system provides early warning to the operator of the oncoming train to provide more reliable protection for distressed vehicles in the railroad crossing and for motorists and pedestrians approaching the railroad crossing.
摘要:
An intelligent wireless communication base station provides communication between individual base stations over an RF radio channel. A control unit in each base station utilizes this communication to facilitate each base station to gather system data regarding the system arrangement of nearby base stations and to facilitate handovers of mobile wireless personal communicators from one base station to a another base station. This control unit is under stored program control and gathers information concerning set up channels of nearby radio ports, a developed list or table of neighbor base stations and signal strength values of nearby channels. Voice channels may be bridged allowing two personal communicators to communicate with each other through a single base station.
摘要:
An apparatus and method synchronizes a communication frame of a newly added base station, in a Time Division Multiple Access (TDMA) communication network, to communication frames in the existing communication network of base stations by operating the newly added base station to receive down link signals of a neighboring active base station and synchronize its receive slot in the communication frame with a corresponding forward time slot of the communication frame of that base station. The receive time slot of the newly added base station is shifted by an offset reference time to establish it own forward time slot. The offset reference time is determined by the time interval required for the base station to change from a forward to a reverse channel.
