Addressable outlet, and a network using same
View Patent ↗An addressable outlet for use as part of local area network based on wiring installed in a building, such as telephone, electrical, cable television, dedicated wiring, and the like. The use of such wiring for data communications networks in addition to the wiring's primary usage creates a need for ways of determining the condition of the network and monitoring this information remotely. Network condition includes such factors as continuity of wiring, connector status, connected devices, topology, signal delays, latencies, and routing patterns. Providing basic processing and addressing capabilities within the outlet permits messaging to and from specific individual outlets, thereby allowing inquiries and reports of the condition of the immediate environment of each outlet. In addition, outlets can be configured with sensors to report on voltage, temperature, and other measurable quantities.
1. An addressable device for coupling packet-based data signals to and from a data unit, for use with service wiring in a building concurrently carrying an analog service signal and the packet-based data signal using frequency division multiplexing, wherein the data signal is carried over a data signal frequency band and the analog service signal is carried over an analog service signal frequency band distinct from the data signal frequency band, and the service signal is one of a telephone signal, a power signal and a CATV signal, the device comprising:
a single housing and, in said single housing;
a wiring connector connectable to the service wiring;
a data filter coupled to the wiring connector for passing only the data signal,
a wiring modem coupled to said data filter and operative to couple to the data signal;
a data connector connectable to a data unit;
a multiport unit comprising a hub, the multiport unit comprising a first port coupled to said wiring modem and a second port coupled to the data connector, said first and second ports being operative to couple data carried by the data signals between said modem and said data connector; and
a processing unit coupled to the multiport unit and comprising an address unit storing an address that uniquely identifies the device,
wherein the processing unit is operative to identify and compose messages associated with said address in a data network,
and wherein said housing is attachable to a wall.
2. The device according to claim 1 , wherein:
the service wiring is a residential telephone wiring;
the analog service signal is an analog telephone signal; and
the device further comprises:
a low pass filter coupled to the wiring connector for passing the analog telephone signal; and
a telephone connector coupled to said low pass filter for coupling the analog telephone signal to a telephone unit.
3. The device according to claim 1 , wherein:
the service wiring is a residential power wiring;
the analog service signal is a power signal; and
the device further comprises:
a low pass filter coupled to the wiring connector for passing the power signal; and
a power connector coupled to said low pass filter for coupling the power signal to an appliance.
4. The device according to claim 1 , wherein:
the service wiring is a residential CATV wiring;
the analog service signal is a CATV signal; and
the device further comprises:
a CATV filter coupled to the wiring connector for passing the CATV signal; and
a CATV connector coupled to said CATV filter for coupling the CATV signal to a CATV unit.
5. The device according to claim 1 , wherein the data signal is Ethernet based, and the address is one of a Media Access Control (MAC) address and an Internet Protocol (IP) address.
6. The device according to claim 1 , further comprising sensors coupled to said processing unit for checking the device status.
7. The device according to claim 1 , wherein the device is further operative to be power fed by a power signal carried over the service wiring.
