In a cable television system switches (119) are located between the splitting point (115) and the subscribers (117), or in the splitting point (115). The switches (119) are used for switching off the signals to and/or from subscribers (117) which intentionally or unintentionally transmit signals to the system and thereby jamming the system for other subscribers. The switches (119) can also be used for effectively disconnecting a particular subscriber permanently or temporarily. |
