Claim 1
Independent Claim
188 words
An intra-premises communication system comprising: an exchange box (10) adapted to be mounted in a premises and having different interfaces (11,12,13) for connection to different networks; a plurality of wired transmission channels (20) routed in the premises to extend from said exchange box (10) and terminate to receptacles (30) installed in said premises, said receptacle (30) having a common connector (32); a plurality of indoor wireless terminals (1,2,3) of different types; a plurality of local transmitter-receivers (41,42,43,44) of different types each detachably and selectively mounted to said common connector (32) of the receptacle (30) for wired communication with one of said different networks through the associated transmission channel (20), each of said local transmitter-receivers having means (81,82) for wireless communication with at least one of said terminals and having conversion means (88) for conversion between information carried by way of said wired communication through said transmission channel and the information carried by way of said wireless communication; said exchange box (10) having switch means for connecting said transmission channels selectively to particular ones of said interfaces (11,12,13) in order to allocate the local transmitter-receivers to the different networks.
Claim 2
Dependent Claim
188 words
An intra-premises communication system comprising: an exchange box (10) adapted to be mounted in a premises and having different interfaces (11,12,13) for connection to different networks; a plurality of wired transmission channels (20) routed in the premises to extend from said exchange box (10) and terminate to receptacles (30) installed in said premises, said receptacle (30) having a common connector (32); a plurality of indoor wireless terminals (1,2,3) of different types; a plurality of local transmitter-receivers (41,42,43,44) of different types each detachably and selectively mounted to said common connector (32) of the receptacle (30) for wired communication with one of said different networks through the associated transmission channel (20), each of said local transmitter-receivers having means (81,82) for wireless communication with at least one of said terminals and having conversion means (88) for conversion between information carried by way of said wired communication through said transmission channel and the information carried by way of said wireless communication; said exchange box (10) having switch means for connecting said transmission channels selectively to particular ones of said interfaces (11,12,13) in order to allocate the local transmitter-receivers to the different networks.
Claim 3
Dependent Claim
47 words
An intra-premises communication system as set forth in claim 1, wherein said wireless terminals include data terminals (1) and wherein said local transmitter-receiver includes means which is cooperative with one of said interfaces to construct a local area network which enables data transmission among said data terminals.
Claim 4
Dependent Claim
53 words
An intra-premises communication system as set forth in claim 1, wherein said wireless terminals include personal handy phone terminals (2) and wherein said local transmitter-receiver includes means for intercommunication with said phone terminals, said interface comprising a private branch exchange (PBX) (12) for connecting of said transmission channels (20) to an outside network.
Claim 5
Dependent Claim
21 words
An intra-premises communication system as set forth in claim 1, wherein said interfaces are arranged to enable intercommunication between said networks.
Claim 6
Dependent Claim
139 words
An intra-premises communication system as set forth in claim 1, wherein said receptacle (30) comprises a base plate (31) carrying a pair of mounting brackets (160) which are pivotally supported at one end to said base plate, and a pair of screws (163) each extending through a periphery of said base plate (31) and through an intermediate portion of said bracket (160), said base plate (31) having a circumference which abuts against a periphery of a mounting hole provided in a mounting surface of said premises with said brackets projecting through said mounting hole, said screws (163) being in threaded engagement with said brackets in such a manner that tightening of screws causes said brackets to expand behind said mounting surface for gripping the periphery of said mounting hole between said bracket and said circumference of said base plate.
Claim 7
Dependent Claim
72 words
An intra-premises communication system as set forth in claim 5, wherein said receptacle (30) has a pair of electrical contacts (156) connected to a power source, said receptacle being formed with a pair of slots (155) which engages with prongs (174) projecting from said local transmitter-receiver (41), said electrical contacts being positioned adjacent said slots to be in electrical connection with said prongs for supplying an electric power to said local transmitter-receiver.
Claim 8
Dependent Claim
43 words
An intra-premises communication system as set forth in claim 5, wherein said receptacle (30) has said connector in the form of a modular jack (32) connected to said transmission channel (20), said local transmitter-receiver having a plug (176) detachable to said modular jack.
