Abstract

Abstract In a power control monitoring system for monitoring a power feed for a cable communications system including n cable landing stations where n is an integer, a network connects m cable landing stations among the n cable landing stations to each other by communications lines other than power feed cables connecting the n cable landing stations where m is an integer equal to or smaller than n. A sender/receiver, which is provided in each of the m cable landing stations, transfers information concerning the power feed with respect to the m cable landing stations to each other. A control and output unit, which is provided in each of the m cable landing stations, gathers the information concerning the power feed with respect to the m cable landing stations and outputs the information so that the information is simultaneously output in the m cable landing stations.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 156 words
A power control monitoring system for monitoring a power feed for a cable communications system including n cable landing stations, where n is an integer, and power feed cables connecting the n cable landing stations, said power control monitoring system comprising: network means, provided separately from said power feed cables, for connecting m cable landing stations among said n cable landing stations to each other by communications lines, where m is an integer equal to or smaller than n; sender/receiver means, provided in each of the m cable landing stations, for transferring information concerning the power feed associated with the m cable landing stations via said network means; and control and output means, provided in each of the m cable landing stations, for gathering and outputting the information concerning the power feed associated with the m cable landing stations and outputting said information so that said information is simultaneously output in the m cable landing stations.
Claim 2
Dependent Claim 156 words
A power control monitoring system for monitoring a power feed for a cable communications system including n cable landing stations, where n is an integer, and power feed cables connecting the n cable landing stations, said power control monitoring system comprising: network means, provided separately from said power feed cables, for connecting m cable landing stations among said n cable landing stations to each other by communications lines, where m is an integer equal to or smaller than n; sender/receiver means, provided in each of the m cable landing stations, for transferring information concerning the power feed associated with the m cable landing stations via said network means; and control and output means, provided in each of the m cable landing stations, for gathering and outputting the information concerning the power feed associated with the m cable landing stations and outputting said information so that said information is simultaneously output in the m cable landing stations.
Claim 3
Dependent Claim 35 words
The power control monitoring system as claimed in claim 1, wherein said control and output means provided in each of the m cable landing stations include display means for displaying said information on a screen.
Claim 4
Dependent Claim 30 words
The power control monitoring system as claimed in claim 1, wherein said control and output means include means for schematically outputting a power feed status of the cable communications system.
Claim 5
Dependent Claim 28 words
The power control monitoring system as claimed in claim 2, wherein said display means include means for schematically displaying a power feed status of the cable communications system.
Claim 6
Dependent Claim 40 words
The power control monitoring system as claimed in claim 1, wherein said control and output means include means for displaying a power up/down procedure for starting or stopping the power feed, and a status of progress of the power feed.
Claim 7
Dependent Claim 38 words
The power control monitoring system as claimed in claim 3, wherein said control and output means include displaying a power up/down procedure for starting or stopping the power feed, and a status of progress of the power feed.
Claim 8
Dependent Claim 48 words
The power control monitoring system as claimed in claim 1, further comprising decision means for determining whether or not a power up/down procedure has been properly performed by referring to the information gathered from the m cable landing stations and predetermined information concerning the m cable landing stations.
Claim 9
Dependent Claim 30 words
The power control monitoring system as claimed in claim 1, further comprising updating means for manually updating the information on the basis of a change in the cable communications system.
Claim 10
Dependent Claim 25 words
The power control monitoring system as claimed in claim 1, further comprising computer simulation means for simulating the power feed for the cable communications system.
Claim 11
Dependent Claim 18 words
The power control system as claimed in claim 1, further comprising means for performing a power up/down procedure.
Claim 12
Dependent Claim 16 words
The power control system as claimed in claim 1, wherein said network means include a network.
Claim 13
Dependent Claim 76 words
The power control system as claimed in claim 1, wherein: said control and output means in one of said m cable landing stations includes means for generating a request signal for instructing each of the other (m-1) cable stations to execute a power up/down procedure; and said control and output means in each of other (m-1) cable landing stations includes means for said m cable landing stations of completion of execution of the power up/down procedure.
