First Claim
Patent Images
1. A method for transmitting a packet of information including a preamble and data throughout a local area network comprising a multiport repeater having a plurality of ports for respectively connecting an end of each of a plurality of coaxial cables to said repeater, a port for connecting a transceiver cable to said repeater, FIFO buffer means, and repeating means, comprising the steps of:
- (a) storing information received on one of said ports in said FIFO buffer means;
(b) regenerating a preamble in response to storage of said received information and transmitting said regenerated preamble on all of said ports except for said one port;
(c) detecting an end of said received preamble at the output of said buffer means and;
(d) always replicating the information stored in said buffer on all of said ports except for said one port in response to completion of said regenerated preamble.

- 4. A local area network comprising first, second and third multiport repeaters, each multiport repeater having a repeater interconnect port, a plurality of local ports and repeating means for coupling all data received at one port of said repeater for transmission at all other ports of said repeater, first, second and third pluralities of signal connection means coupled to said pluralities of local ports of said first, second and third multiport repeaters respectively, first, second and third repeater interconnection means coupled to said repeater interconnect ports of said first, second and third multiport repeaters respectively, and a repeater interconnect bus means connected to each of said repeater interconnection means at different junctions therealong, whereby data transmitted by a device coupled to any one of said signal connection means is received by all other devices coupled to said pluralities of signal connection means.
- 8. A global local area network connected to a standard Ethernet coaxial cable by means of transceiver, said local area network comprising first, second and third multiport repeaters, each multiport repeater having a repeater interconnect port, a plurality of local ports and repeating means for coupling all data received at one port of said repeater for transmission at all other ports of said repeater, first, second and third pluralities of signal connection means coupled to said pluralities of local ports of said first, second and third multiport repeaters respectively, first, second and third repeater interconnection means coupled to said repeater interconnect ports of said first, second and third multiport repeaters respectively, and a repeater interconnect bus means connected to each of said repeater interconnection means at different junctions therealong, said first multiport repeater having a transceiver connection port connected to said transceiver by a transceiver connection means, whereby data transmitted by a device coupled to any one of said signal connection means is received by all other devices coupled to said pluralities of signal connection means, and wherein each of said signal connection means has higher signal attenuation and lower resistance to interference than said standard Ethernet coaxial cable.
