The invention relates to sending a data stream transmitting method wherein it can stop the standby mode of at least one transmission/reception device (LTU NTU) function stopping signal (101) by the system control device (100). at least one data transfer path (102) exchange-end transmission coefficients stored in coefficient storage device exchanging end (103) by at least one data transfer path (102) stop signal from the transmitting/receiving device of the exchange terminal (LTU) to the user end of the transmission/reception device (NTU). coefficient storing device (104) is transmission coefficient on the user end of the at least one data transmission path (102) of the transmission/reception device (NTU) is stored in the user terminal of the transmission/reception device (NTU) by the user terminal; transmission/reception device (LTU) stop signal (101) back to the exchange end from the transmitting/receiving device of the user terminal (NTUs) transmitting by the at least one data transmission path (102) stopping data stream of transmission to be transmitted therefore respectively stopped at the transmitting/receiving device of the user terminal (NTUs) and an inactive state of the transmitting/receiving device of the exchange terminal (LTU).

The invention relates to a method for transmitting data streams that are to be transmitted wherein at least one transmitter/receiver device (LTU NTU) can be deactivated in standby mode wherein a deactivation signal (101) is supplied by a system control device (100); transmission coefficients on the exchange side of at least one transmission path (102) are stored in a coefficient storage device (103) on the exchange side; the deactivation signal is transmitted via the at least one data transmission path (102) from the transmitter/receiver device (LTU) on the exchange side to the transmitter/receiver device (NTU) on the subscriber side; transmission coefficients on the subscriber side of the at least one transmission path (102) are stored in a coefficient storage device (104) on the subscriber-side of the transmitter/receiver device (NTU) on the subscriber side; the deactivation signal (101) is transmitted back from the transmitter/receiver device (NTU) on the subscriber side to the transmitter/receiver device (LTU) on the exchange side via the at least one data transmission path (102) and the transmission of the data streams to be transmitted is stopped whereby the transmitter/receiver device (NTU) on the subscriber side and the transmitter/receiver device (LTU) on the exchange side are respectively deactivated in standby mode.
