Abstract
Abstract A shared receiver demand priority repeater (20) for use in a shared receiver demand priority repeater network having at least two transmission media (30), has a demand priority repeater core (22). A receiver (26) is coupled to the demand priority repeater core (22). A multiplexer (28) is coupled between the receiver (26) and the at least two transmission media (30). A transmitter (24) for each the transmission media (30) is coupled between the demand priority repeater core (22) and the transmission media (30). The multiplexer (28) couples a selected one of the transmission media (30) to the receiver (26) in response to the demand priority repeater core (22). The multiplexer can comprise an address selectable switch. A method is described for interfacing a demand priority repeater core to at least two downlinks, each downlink coupled to a device.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
94 words
A shared receiver demand priority repeater network comprising: a demand priority repeater core; at least two transmission media; a receiver coupled to said demand priority repeater core; a multiplexer coupled between said receiver and said at least two transmission media; a transmitter for each of said at least two transmission media, said transmitter coupled between said demand priority repeater core and one of said at least two transmission media; wherein said multiplexer couples a selected one of said at least two transmission media to said receiver in response to said demand priority repeater core.
Claim 2
Dependent Claim
15 words
The network as recited in claim 1 wherein said multiplexer comprises an address selectable switch.
Claim 3
Dependent Claim
20 words
The network as recited in claim 1 wherein said at least two transmission media comprise unshielded twisted four pair cable.
Claim 4
Dependent Claim
19 words
The network as recited in claim 1 wherein said at least two transmission media comprise shielded twisted pair cable.
Claim 5
Dependent Claim
19 words
The network as recited in claim 1 wherein said at least two transmission media each comprise an optical fiber.
Claim 6
Dependent Claim
17 words
The network as recited in claim 1 wherein said demand repeater core routes an Ethernet data frame.
Claim 7
Dependent Claim
18 words
The network as recited in claim 1 wherein said demand repeater core routes a token ring data frame.
Claim 8
Dependent Claim
100 words
In a shared receiver demand priority repeater network having at least two transmission media, a demand priority repeater comprising: a demand priority repeater core; a receiver coupled to said demand priority repeater core; a multiplexer coupled between said receiver and said at least two transmission media; a transmitter for each of said at least two transmission media, said transmitter coupled between said demand priority repeater core and one of said at least two transmission media; wherein said multiplexer couples a selected one of said at least two transmission media to said receiver in response to said demand priority repeater core.
Claim 9
Dependent Claim
15 words
The device is recited in claim 8 wherein said multiplexer comprises an address selectable switch.
Claim 10
Dependent Claim
17 words
The device as recited in claim 8 wherein said demand repeater core routes an Ethernet data frame.
Claim 11
Dependent Claim
18 words
The device as recited in claim 8 wherein said demand repeater core routes a token ring data frame.
Claim 12
Independent Claim
67 words
A method of interfacing a demand priority repeater core to at least two downlinks, each downlink coupled to a device, the method comprising the steps of: selecting a device; selectively coupling a downlink corresponding to said selected device to a receiver; sending an acknowledgment to said selected device wherein enabling said selected device to transmit a response; receiving said response from said selected device; processing said response.
Claim 13
Dependent Claim
18 words
The method as recited in claim 12 further comprising the step of prioritizing a request to transmit response.
Claim 14
Dependent Claim
20 words
The method as recited in claim 13 wherein said prioritizing comprises evaluating a level of said request to transmit response.
Claim 15
Dependent Claim
17 words
The method as recited in claim 12 wherein said demand repeater core routes an Ethernet data frame.
Claim 16
Dependent Claim
18 words
The method as recited in claim 12 wherein said demand repeater core routes a token ring data frame.
Claim 17
Dependent Claim
21 words
The method as recited in claim 12 wherein a multiplexer couples said downlink corresponding to said selected device to said receiver.
Claim 18
Dependent Claim
15 words
The method as recited in claim 17 wherein said multiplexer comprises an address selectable switch.
Claim 19
Dependent Claim
20 words
The method as recited in claim 13 wherein the step of prioritizing a request is a demand priority access method.
