•
Voice. Telephony over IP services. The InternetBox behaves like a telephone
receiver to which the analog telephones used on the switched telecommunica-
tions network (STN) are connected.
•
Video. IPTV for the broadcasting of TV channels over IP networks and video
on demand (VoD).
•
IP services. Domestic mobile telephony, home automation (like electrical
power management and family server), and so forth. These services will turn
the InternetBox into a true smart gateway in the near future.
Each of these services must be routed to the end user (television set, telephone,
computer, IP household appliances, and so forth) via an Ethernet network. For this
purpose, the PLC local area network is an excellent solution as it uses a network
available in any building.
As illustrated by Figure 6.9, these services require an Ethernet link between the
InternetBox and the video decoder or the telephones; this link can be provided by
PLC devices.
Internet access providers already provide the following devices integrating PLC
products or completed by them:
