Abstract
There is provided interface apparatus (40) for use in a broadband and/or CATV network (10), the apparatus (40) comprising signal separation means (50, 50′) to create separate downstream and upstream signal paths (46, 48′) and an amplifier means (54) for amplifying upstream signals, wherein the amplifier means (54) is positioned in the upstream signal path and is in communication with a signal detection means (56) operable to power the amplifier means (54) dependent on a signal level of the upstream signal. The signal detection means (56) is positioned downstream of the amplifier means in the upstream path. The signal detection means (56) incorporates a switching element (58) responsive to a detected signal level to interrupt power (60) to the amplifier means (54) and so prevent passing along the upstream path.
