A multifunctional amplifier for Time Division Duplex signals and Frequency Division Duplex signals in Very High Bit-Rate Subscriber Line, is disclosed. The multifunctional amplifier may include a first and second bidirectional terminals, at least one first filter connected between said first and second bidirectional terminals for bypassing signals in a first configuration, an amplifier circuit arranged in a signal path between first and second bidirectional terminals to amplify said signals, the amplifier circuit being operable in a second configuration for amplifying said signals in one direction along the signal path and a third configuration for amplifying said signals in the opposite direction along the signal path, and a control circuit arranged to control said amplifier circuit to change configuration.

Multifunctional amplifier

A TDD signal booster includes first and second bidirectional terminals and an amplifier circuit arranged in a signal path between said first and second terminals. The amplifier circuit is to amplify TDD signals received at one of said first and second terminals for transmission from the other of said first and second terminals. The amplifier circuit is operable in a first configuration for amplifying TDD signals in one direction along the signal path and a second configuration for amplifying TDD signals in the opposite direction along the signal path. A control circuit is arranged to detect a silent period in said TDD signals, e.g. the guard period, and, in response to detecting the silent period, control said amplifier circuit to change configuration.

Time-division duplexing signal booster

A system and method are provided herein for managing an amplifier at an intermediate location in a twisted pair line between a digital subscriber line (DSL) access multiplexer and a customer premises equipment, for high data rate broadband operation. The system may include a DSL access multiplexer, an amplifier, a local communication interface and a host computer, programmed to execute an element management system service application.

Element management system for analog amplifier without channel management

A method for estimating downstream gain and upstream gain of an amplifier at an intermediate location in a twisted pair line between a DSL Access Multiplexer (DSLAM) and a customer premises equipment (CPE) for high data rate broadband operation. The method includes: an offline calibration process for obtaining offline tables, and an estimation process including: setting the downstream gain and the upstream gain to a set of predefined gains in the twisted pair line when activated and getting an indication if the line is in ShowTime. In case the line is in ShowTime, the estimation process further measures the downstream/upstream signal level, estimates the distance from the amplifier to the CPE and distance from the amplifier to the to the CPE and the distance from the amplifier to the DSLAM, and obtains the upstream/downstream gains.

Method for setting analog amplifier gains using ShowTime signals

A device for managing signal transport, on a cable level, in a communication system, and a method for using same, are provided herein. The device is connectable between one or more access multiplexers (e.g., Very-high-speed Digital Subscriber Loop Access Multiplexer (VDSLAM) or a switch) and a cable in said communication system. The device includes: a plurality of access multiplexer-side transceivers connectable to access multiplexer-related physical medium, associated with said one or more access multiplexers; a plurality of customer-side transceivers connectable to respective customer-related wire pairs of said cable; and a processor connected to said access multiplexer-side transceivers and said customer-side transceivers, said processor comprising means for reducing crosstalk among said customer-related wire pairs. In some embodiments, vectoring is used for the crosstalk reduction, thus implementing a so-called cable level vectoring (CLV).
