Abstract
Abstract A centralized supervisory system in an automatic switching system including at least one remote office with a first time-division switching system and a first supervisory unit, and a central office with a second time-division switching system and a second supervisory unit. The first time-division switching system and the second time-division switching system being connected by a time-division multichannel line. Supervisory data output from the first supervisory unit are allocated to one or more predetermined channels on the time-division multichannel line, so that the supervisory data output from the first supervisory unit are transferred through the time-division multichannel line to the second supervisory unit and are centrally supervised therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
242 words
A centralized supervisory system in an automatic switching system, comprising: at least one remote office having a remote-office time-division switching system and a remote-office supervisory unit for supervising the system status of said remote-office time-division switching system; at least one first time-division multichannel line operatively connected to said at least one remote office, and having predetermined channels for transferring communication data representing voice signals; a central office having a central office time-division switching system connected through said at least one first time-division multichannel line to said at least one remote office, and a centralized supervisory unit for receiving supervisory data, representing at least the system status of said remote office, from said remote-office supervisory unit of said at least one remote office and for centrally supervising the received supervisory data, said central-office time-division switching system having predetermined output signal lines; first means, operatively connected to said remote office supervisory unit and said remote office time-division switching system, for allocating said supervisory data from said remote-office supervisory unit of said at least one remote office to one or more of the predetermined channels on said at least one first time-division multichannel line; and second means, operatively connected to said central office time-division switching system and said centralized supervisory unit, for connecting the predetermined output signal lines of said central-office time-division switching system to said centralized supervisory unit, the predetermined output signal lines transferring said supervisory data output from said central-office time-division switching system.
Claim 2
Dependent Claim
242 words
A centralized supervisory system in an automatic switching system, comprising: at least one remote office having a remote-office time-division switching system and a remote-office supervisory unit for supervising the system status of said remote-office time-division switching system; at least one first time-division multichannel line operatively connected to said at least one remote office, and having predetermined channels for transferring communication data representing voice signals; a central office having a central office time-division switching system connected through said at least one first time-division multichannel line to said at least one remote office, and a centralized supervisory unit for receiving supervisory data, representing at least the system status of said remote office, from said remote-office supervisory unit of said at least one remote office and for centrally supervising the received supervisory data, said central-office time-division switching system having predetermined output signal lines; first means, operatively connected to said remote office supervisory unit and said remote office time-division switching system, for allocating said supervisory data from said remote-office supervisory unit of said at least one remote office to one or more of the predetermined channels on said at least one first time-division multichannel line; and second means, operatively connected to said central office time-division switching system and said centralized supervisory unit, for connecting the predetermined output signal lines of said central-office time-division switching system to said centralized supervisory unit, the predetermined output signal lines transferring said supervisory data output from said central-office time-division switching system.
Claim 3
Dependent Claim
148 words
A centralized supervisory system as set forth in claim 1, wherein said first means is included in said remote-office time-division switching system of said at least one remote office, and said remote-office time-division switching system comprises: a first multiplexer, operatively connected to said remote office supervisory unit, for multiplexing the supervisory data from said remote-office supervisory unit with communication data to provide a multichannel with predetermined one or more channels being allocated for said supervisory data; a first time-division network, operatively connected to said multiplexer and said at least one first time-division multichannel line, for forming a desired speech path between said first multiplexer and said at least one first time-division multichannel line; and a central processing unit, operatively connected to said first time-division network, for controlling said first time-division network, so that said supervisory data are allocated to said predetermined channels on said first time-division multichannel line.
Claim 4
Dependent Claim
99 words
A centralized supervisory system as set forth in claim 2, wherein said second means is included in said central-office time-division switching system, and said central-office time-division switching system comprises: a second time-division network, operatively connected to said first time-division multichannel line, for forming desired speech paths between said at least one first time-division multichannel line and the output of said second time-division network; and a demultiplexer, operatively connected to said second time-division network and to said centralized supervisory unit, for demultiplexing the output data from said second time-division network to provide said supervisory data to said centralized supervisory unit.
Claim 5
Dependent Claim
130 words
A centralized supervisory system as set forth in claim 3, further comprising: a second time-division multichannel line separate from said first time-division multichannel line and connected between said first-time division network of said at least one remote office and said second time-division network of said central-office time-division switching system; and third means, operatively connected to said remote-office supervisory unit and said first time-division network, for allocating said supervisory data from said remote-office supervisory unit to one or more predetermined channels on said second time-division multichannel line, said second time-division network further forming desired speech paths between said second time-division multichannel line and the output of said second time-division network, said first time-division multichannel line being a regular time-division highway and said second time-division multichannel line being a standby time-division highway.
Claim 6
Dependent Claim
35 words
A centralized supervisory system as set forth in claim 4, wherein another speech path is formed between the output of said first multiplexer and said second time-division multichannel line by said first time division network.
