Abstract
The method for terminating an operation of a CPE device, which comprises a front-end component for an xDSL connection of a Central Office Equipment supplying a multitude of customers, comprises the steps of: sending a power loss information to the Central Office Equipment in case of a power loss or a switch-off operation of the CPE device and powering the front-end component for a predetermined time to avoid a termination impedance change of the front-end component, by keeping the supply power up for the front-end component, to keep the termination impedance stable as long as necessary for the Central Office Equipment to avoid introduction of non-cancelled crosstalk, which may arise in xDSL connections of other customers.
