A multifunctional amplifier for Time Division Duplex (TDD) signals in a TDD Digital Subscriber Line (DSL) and Frequency Division Duplex (FDD) signals in Very High Bit-Rate Subscriber Line (VDSL2), comprising:
- 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 said first and second bidirectional terminals to amplify said signals, said 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;
- a control circuit configured to monitor a guard interval of the signals between said first and second bidirectional terminals, and, in a case a drop of the signals during the guard interval is detected, to set the amplifier to operate for G.Fast service, and in a case the signal is stable, set the amplifier for VDSL2 V35b service.
An electronic circuit installed over copper lines, comprising:
- first bidirectional terminals and second bidirectional terminals both for signals in first and second different frequency spectrums;
- at least one first filter connected between said first and second terminals for bypassing signals in a first configuration;
- an amplifier circuit arranged in a signal path between said first and second bidirectional terminals to amplify signals received at one of said first bidirectional terminals for transmission from one of said second bidirectional terminals, said amplifier circuit being operable in a second configuration,
- wherein said copper lines connect said first bidirectional terminals and said second bidirectional terminals via said first filter and said amplifier circuit.
A communication system, the communication system comprising:
- customer provider equipment for sending Frequency Division Duplex (FDD) signals to and receiving FDD signals from service provider equipment in a Very High Bit-Rate Subscriber Line (VDSL2);
- first bidirectional terminals and second bidirectional terminals both for signals in first and second different frequency spectrums;
- at least one first filter connected between said first and second terminals for bypassing signals in a first configuration;
- and
- an amplifier circuit arranged in a signal path between said first and second bidirectional terminals to amplify signals received at one of said first bidirectional terminals for transmission from one of said second bidirectional terminals, said amplifier circuit being operable in a second configuration,
- wherein said customer provider equipment comprises a reverse power feeding (RPF) unit arranged to feed power via wires which also serve for transmission of said FDD signals.
