Local area network of serial intelligent cells
First Claim
1. A device that is part of a local area network in a building for coupling a digital data signal to a data unit, the network including at least part of an existing telephone wire pair that is at least in part in walls of the building and is terminated by an outlet, the wire pair carrying a frequency multiplexed analog service signal and a digital data signal, said device comprising:
- a telephone connector for connecting said device to the telephone wire pair;
a filter coupled to said telephone connector and having a data signal port operative to pass only the digital data signal;
a modem coupled to said data signal port for bi-directional digital data signal communication with one or more additional modems of the same type as said modem over the telephone wire pair;
a data connector for connecting to the data unit;
a data transceiver coupled between said data connector and said modem and operative to effect full-duplex serial digital data communication with the data unit;
a power port connectable to a power signal from a power signal source;
a power supply coupled between said power port and said modem for DC powering said modem from the power signal; and
a single enclosure housing said filter, said power supply, said modem and said data connector, wherein said device is addressable in the local area network.
