The equipment to be installed in the user’s home is the PLC modem. This modem allows the end user to access the services by means of their PC or a phone. The PLC modem connects end user terminals to the network. Available interfaces for the PLC modem are RJ45 for Ethernet, USB and RJ11 for telephone.

Following upstream the low voltage grid, we find a Repeater. It improves the signal quality along the network.

In the transformer premises there is the PLC master facility. It controls and gathers the information traffic (voice and data) that end users send and receive. It also delivers it to the external network. This equipment is also known as Head End Modem.



The pilot Test

For the pilot test, two head end modems have been installed in the Tussol and High School transformer premises so as to give coverage to users depending on them.

In the following map we can see the coverage of the Tussol station (ET17) with all its lines.
