Abstract

Abstract A switching system is arranged to provide selectively changeable class of service treatments on each station served from the system. Auxiliary circuits, individually associated with the switching system line appearance of each station, are arranged with magnetic latching relays for controlling the class of service cross-connect patch field associated therewith in accordance with data transmitted to the auxiliary circuit from an attendant console. The auxiliary circuit of a selected station responds to interrogation signals from the console by transmitting to the console signals representing the class of service currently effective on that station.

Claim 2
Dependent Claim 112 words
In a communication system a station, means including a wired cross-connection field for defining a plurality of class or service designations for said station, to one of which designations said station is normally assigned, an attendant''s console, switching means controlled by the particular station class of service designation assigned for completing connections involving said station, said assigned designation being provided to said switching means upon interrogation of said wired cross-connection field, means including relay means individual to said station and controllable from said attendant''s console for inhibiting said normally assigned class of service designation and for selectively assigning a different one of said plurality of class of service designations to said station.
Claim 3
Dependent Claim 46 words
The invention as set forth in claim 1 further comprising means individual to said station and controllable from said attendant''s console for interrogating said station so as to obtain the class of service designation currently assigned thereto, and means at said console for displaying said designation.
Claim 4
Dependent Claim 93 words
In a telephone switching system a switching network, a plurality of stations each having a line appearance in said network, a cross-connection field for associating a class of service with each of said line appearances, a plurality of consoles, means for selectively establishing connections between one of said consoles and one of said line appearances, and means individual to said one line appearance and selectively responsive to signals received over said connections from said one console for controlling said cross-connection field to change the class of service associated with said one line appearance.
Claim 5
Dependent Claim 93 words
In a telephone switching system a switching network, a plurality of stations each having a line appearance in said network, a cross-connection field for associating a class of service with each of said line appearances, a plurality of consoles, means for selectively establishing connections between one of said consoles and one of said line appearances, and means individual to said one line appearance and selectively responsive to signals received over said connections from said one console for controlling said cross-connection field to change the class of service associated with said one line appearance.
Claim 6
Dependent Claim 39 words
The invention as set forth in claim 3 wherein said cross-connection controlling means further comprises means selectively responsive to signals from said one console for transmitting information to said one console corresponding to said currently associated class of service.
Claim 7
Dependent Claim 64 words
The invention as set forth in claim 3 wherein said selectively responsive cross-connection controlling means further comprises a plurality of relays the contacts of which are operable to interrupt the class of service associated with said line appearance and to substitute a different class of service therefor and means for enabling selected ones of said relays while concurrently releasing unselected ones of said relays.
Claim 8
Dependent Claim 141 words
The invention as set forth in claim 3 wherein said consoles each comprise means for transmitting a plurality of unique signals, means for serially receiving digital data, and means for transmitting digital data to a connected station, and wherein said selectively responsive cross-connection controlling means further comprises a plurality of relays the contacts of which are operable to interrupt the class of service associated with said line appearance and to substitute a different class of service therefor, a register operable upon one signal from said connected console for serially storing digital data received from said console and operable upon another signal from said connected console for transmitting thereto digital data stored in said register and means responsive to receipt of said one signal from said connected console for releasing and enabling said relays in accordance with data stored in said register.
Claim 9
Dependent Claim 39 words
The invention as set forth in claim 6 wherein said cross-connection controlling means further comprises means responsive to receipt of said another signal from said connected console for transmitting said stored digital data to said console data receiving means.
Claim 10
Dependent Claim 120 words
An auxiliary circuit for providing a plUrality of class of service treatments on a line in a communication switching system having call completion means operable to establish connections involving said line in accordance with an enabled one of said class of service treatments and wherein unique signals and data corresponding to a selected one of said class of service treatments are transmitted over said line; said auxiliary circuit comprising means for detecting the transmission of a first unique signal, means enabled by said detecting means for storing any of said transmitted data, and means concurrently responsive to the enabling of said detecting means and to storage of said data for enabling the class of service treatment corresponding to said data.
Claim 11
Dependent Claim 120 words
An auxiliary circuit for providing a plUrality of class of service treatments on a line in a communication switching system having call completion means operable to establish connections involving said line in accordance with an enabled one of said class of service treatments and wherein unique signals and data corresponding to a selected one of said class of service treatments are transmitted over said line; said auxiliary circuit comprising means for detecting the transmission of a first unique signal, means enabled by said detecting means for storing any of said transmitted data, and means concurrently responsive to the enabling of said detecting means and to storage of said data for enabling the class of service treatment corresponding to said data.
Claim 12
Dependent Claim 60 words
The invention as set forth in claim 8 wherein said class of service information is ascertained by said call completion means by interrogation of a cross-connection field and wherein said class of service treatment enabling means further comprises relay means operable in response to changes in said stored data for changing the cross-connection field in accordance with the changed data.
Claim 13
Dependent Claim 51 words
The invention as set forth in claim 8 wherein said auxiliary circuit further comprises means for detecting the transmission of a second unique signal, and means enabled by said second signal detecting means for transmitting over said line data from said storage means corresponding to said enabled class of service treatment.
Claim 14
Dependent Claim 86 words
The invention as set forth in claim 8 wherein said storage means comprises a multistage counter wherein said stored date is represented by active and nonactive stages, and said class of service-enabling means further comprises a plurality of latching relays each associated with a unique one of said counter stages, means for momentarily applying operating potential to the relays associated with active stages of said counter, and means for momentarily applying releasing potential to operated ones of said relays associated with nonactive stages of said counter.
Claim 15
