The media can be either distribution line carrier, telephone (including isDN), radio or other electrical or optical systems; and they may be used for local or remote data exchanges. Meter reading and programming may be performed manually by a meter reader, or supported by means of a local communication system, or automatically by means of a remote communication system. Manual meter reading means that the reader has access to the meter and reads each register, while "supported" meter reading implies the use of a communication system or a local bus system and a hand-held unit (HHU). Fully automatic meter reading implies a remote communication system such as those i
