Abstract
Abstract A communication system has multiple and uniformly weighted station interconnected by a shared digital bus. A particular station comprises globally relevant information, and, with a predetermined maximum recurrence time, transmits a data packet representing such item to any other interested station. If unanimous counter signalization occurs, the item is in order, other wise updating thereof is undertaken. The unanimity is either by positive signalization, or by default.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
83 words
A communication system having multiple and uniformly weighted stations that are interconnected by a shared digital bus, characterized in that a particular station comprising a globally relevant information item comprises means for, recurrently with a predetermined maximum recurrence interval transmitting a data packet representing such information item for unanimous counter signalization thereto by at least a relevant subset of actually interconnected stations thereto, but upon absence of such unanimous counter signalization initiating an updating action with respect to its own relevant information item.
Claim 2
Dependent Claim
21 words
A communication system as claimed in Claim 1, wherein said globally relevant information is an address of the particular station itself.
Claim 3
Dependent Claim
19 words
A communication system as claimed in Claim 1 or 2, wherein any physical counter signalization actually occurring means non-unanimity.
Claim 4
Dependent Claim
26 words
A communication system as claimed in Claim 2, wherein the data packet contains said address as a destination address and said unanimity represents an unpresent signalization.
Claim 5
Dependent Claim
25 words
A communication system as claimed in Claim 2 or 4, wherein said updating action is generating a new address according to a predetermined updating pattern.
Claim 6
Dependent Claim
28 words
A communication system as claimed in any of Claims 1 to 5, wherein said updating is followed by signalling result of said updating to any other relevant station.
Claim 7
Dependent Claim
28 words
A communication system as claimed in any of Claims 1 to 6, and comprising distinguishing means for distinguishing among actual recurrence intervals of respective ones among said stations.
Claim 8
Dependent Claim
19 words
A communication system as claimed in any of Claims 1 to 7, wherein said digital bus is single channel.
Claim 9
Dependent Claim
18 words
A communication system as claimed in any of Claims 1 to 8 and configured as a home system.
Claim 10
Dependent Claim
73 words
A station interfaceable to a communication system as claimed in any of Claims 1 to 9 and having accommodating means for accommodating a globally relevant information, transmission means for recurrently with a predetermined maximum recurrence interval transmitting a data packet representing such information item, detection means for thereupon detecting unanimous counter signalization as emanating from other stations connected, and updating means for under absence of said unanimous counter signalization updating said information item.
