CLAIMS:

What is claimed is:

1 . A system, comprising:

a plurality of communication units connected to each other by communication lines, wherein each communication unit comprises

at least one receiving element to receive a signal from another communication unit, and

at least one transmitting element to transmit a signal to another communication unit, and wherein

at least one of the communication units is to act as a master unit and the other communication units are to act as slave units, wherein the slave units further comprise

a regenerating element to electrically regenerate the received signal and propagate the regenerated signal to another communication unit.

2. The system of claim 1 , wherein the communication units are connected in a daisy chain manner.

3. The system of claim 1 , wherein the regenerating element is controlled by a controller.

4. The system of claim 1 , wherein the signals transmitted by the master unit correspond to data frames.

5. The system of claim 4, wherein each data frame comprises an address field.

6. The system of claim 5, wherein the slave unit which is addressed in the address field is to transmit a response to the master unit, and the master unit is to receive the response.

7. The system of claim 1 , wherein the communication units are connected to each other by a plurality of signal lines.

8. A method, comprising:

transmitting a signal between a plurality of communication units connected to each other by communication lines,

receiving the transmitted signal at one of the communication units;

electrically regenerating the received signal and propagating it to another one of the communication units.

9. The method of claim 8, wherein

at least one of the communication units acts as a master unit and the other communication units act as slave units,

the method further comprising: transmitting from the master unit a signal across the communication line to the slave units, and

electrically regenerating, by the slave unit, the received signal and propagating it to another communication unit.

10. The method of claim 9, further comprising:

transmitting from the master unit a configuration signal across the communication line to one of the slave units, and

receiving the configuration signal at the one of the slave units.

11 . The method of claim 8, further comprising

controlling the regenerating of the received signal by a controller.

12. The method of claim 8, wherein the transmitted signals correspond to data frames and each data frame comprises an address field, the method further comprising:

transmitting, by the slave unit which is addressed in the address field, a response to the master unit, and

receiving, by the master unit, the response.

13. The method of claim 10, further comprising:

causing the one slave unit, by the received configuration signal, to reset to an initial state.

14. The method of claim 8, further comprising:

transmitting, with the transmitted signal, a command which, upon reception of the signal, causes the receiving communication unit to enable or disable at least one of the electrical regenerating of the signal and the propagating of the signal.

15. A non-transitory program product having computer readable code stored thereon that, when executed by a computing device, causes the computing device to:

transmit a signal from a communication unit which acts as a master unit to a plurality of communication units which act as slave units across communication lines by which the communication units are connected to each other,

receiving the transmitted signal at one of the slave units, and

controlling the electrical regeneration of the received signal and the propagation of the regenerated signal to another one of the communication units.
