ABSTRACT:
In a method and an arrangement for controlling the operating mode of a subscriber line interface circuit by mode control signals from a control circuit which is connected to the subscriber line interface circuit, the subscriber line interface circuit includes at least one latch which is interconnected between the control circuit and the subscriber line interface circuit. The latch is adapted to latch the mode control signals received from the control circuit in response to latch enable signals received from the control circuit, and to apply those latched mode control signals to the subscriber line interface circuit to control its operating mode.
