The invention relates to a remote unit for use in conjunction with a communications network. The remote unit includes a network interface which provides an interface between a premises communication system and a first network. The interface permits the premises communication system to receive at least one service over the first network. The remote unit also includes a detector for detecting a cross-connection to a second network which is also connected to the premises communication system.
