Abstract

In a subscriber line interface circuit having an amplifier (16) for generating private metering signals to be transmitted through the subscriber line interface circuit to a subscriber station via a subscriber line (2, 3), the amplitude of the private metering signals is adapted to the length of the subscriber line (2, 3) in that the amplitude is adapted and latched in discrete steps to the DC line voltage once the subscriber station goes off-hook and unlatched when the state of the subscriber line interface circuit changes to stand-by mode.
