Digital data transmission system having additional bits for auxiliary data |
摘要 |
Data transmission system for transmitting data on a cable and in two directions between two terminal stations (LTE1/2) and via repeater stations (REP1/2). Each terminal station has a sender/receiver (CODEC) and each repeater station has a receiver/sender (CODEC1/2) for each direction. Each station is able to convert predetermined 5-bit data words and auxiliary information into predetermined 6-bit data words and to extract auxiliary information from these 6-bit words. In the case of cable rupture the receiver for one direction in a repeater station is connected to the receiver for the other direction.
