High-speed ADSL: digital using twisted pair;
TV cable: analog or digital using coaxial cable;
155/622 Mbps FTTH: using optical fiber; and
Wireless transceiver: (possibility of MMDS, LMDS).
Combining these functions offers the opportunity for innovation.
At least one CPI adapter is required for each type of cable or network that extends within the residence. In many cases, a single adapter may be able to service several in-residence cables, such as multiple telephone extensions.
Examples of CPI adapters include:
NTSC TV adapter;
MPEG2 TV adapter;
POTS(s): one or more phone extensions w/optional services;
High-speed digital networks: data network (e.g., Ethernet);
Low-speed home automation networks: home control (X-10, CEBus, LonWorks, SmartHouse);
Low-voltage systems (security, sprinklers and low-voltage contacts/relays); and
