available for the IP network applications based on the PLC network. According to

this table, it is important to find an outlet 5 that gives a minimum 10-Mbit/s dis-

played throughput.

The analog telephony flow originating from the Internet connection and avail-

able on the RJ-11 connector of the InternetBox connected to the telephone jack can

also be broadcast over the electrical network.

Wingoline PLC devices from Niroda, for example, operate in the 3.3- to

8.2-MHz frequency band according to a proprietary communication protocol dif-

ferent from that of HomePlug devices. The PLC network created with Niroda

devices is therefore not interoperable with a HomePlug PLC network. Up to 24

Niroda PLC devices can be placed on the same electrical network for adding analog

telephone lines.

Figure 10.5 illustrates the possible connectivities from the InternetBox provided

by the IAP with the following PLC networks:

•

HomePlug Ethernet PLC network used for connecting the IP terminals of the

house to the InternetBox Ethernet jacks;

•

RJ-11 PLC network used for connecting analog telephone devices to the

InternetBox voice jack;

•

RJ-11 PLC network used for connecting the InternetBox to the France

Télécom voice jack via the house electrical network.
