Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 182 words
In a telephone switching system comprising one or more offices including a calling line and a plurality of distinct called directory numbers; an announcement machine; intercept means for intercepting a call from said calling line to a selected one of said called numbers for establishing a connection between said calling line and said announcement machine, said intercept means including means for receiving an intercept service request, said request including said selected called number, store means in which said called directory numbers and manifestations of predetermined signals respectively associated therewith are stored such that the manifestation associated with each of said called numbers is determined by locating in said store its associated directory number, means responsive to said request for retrieving from said store the manifestation associated with said selected called number including means for searching said store for selected called number , and means for operating said announcement machine to return an audio announcement to said calling line; radio signal transmission circuitry; and means under control of said intercept means for operating said radio signal transmission circuitry to transmit said retrieved manifestations.
Claim 2
Dependent Claim 182 words
In a telephone switching system comprising one or more offices including a calling line and a plurality of distinct called directory numbers; an announcement machine; intercept means for intercepting a call from said calling line to a selected one of said called numbers for establishing a connection between said calling line and said announcement machine, said intercept means including means for receiving an intercept service request, said request including said selected called number, store means in which said called directory numbers and manifestations of predetermined signals respectively associated therewith are stored such that the manifestation associated with each of said called numbers is determined by locating in said store its associated directory number, means responsive to said request for retrieving from said store the manifestation associated with said selected called number including means for searching said store for selected called number , and means for operating said announcement machine to return an audio announcement to said calling line; radio signal transmission circuitry; and means under control of said intercept means for operating said radio signal transmission circuitry to transmit said retrieved manifestations.
Claim 3
Dependent Claim 31 words
In a telephone switching system according to claim 1 wherein said last mentioned means includes a signal generator connectable under control of said intercept means to said radio signal transmission circuitry.
Claim 4
Dependent Claim 102 words
A telephone switching system comprising one or more offices having a plurality of distinct directory numbers, intercept means including file store means operative incident to the interception of a call to a selected one of said directory numbers and in response to a request for intercept service, said request including said selected directory number, said intercept means being operative for providing data relative to said selected directory number, transmitter means, and means for operating said transmitter means in accordance with said data provided by said file store means, whereby a signal is transmitted to a receiver associated with said selected directory number.
Claim 5
Dependent Claim 102 words
A telephone switching system comprising one or more offices having a plurality of distinct directory numbers, intercept means including file store means operative incident to the interception of a call to a selected one of said directory numbers and in response to a request for intercept service, said request including said selected directory number, said intercept means being operative for providing data relative to said selected directory number, transmitter means, and means for operating said transmitter means in accordance with said data provided by said file store means, whereby a signal is transmitted to a receiver associated with said selected directory number.
Claim 6
Dependent Claim 33 words
A telephone switching system according to claim 3 further comprising audio announcement means operative in accordance with said data provided by said file store means for generating an announcement relative to said call.
Claim 7
Dependent Claim 169 words
In a telephone switching system including means for intercepting calls to selected directory numbers and for providing an audio message to the calling party; said intercepting means including trunk circuit means for receiving intercepted calls, means for storing information relative to said selected directory numbers, means utilizing the directory number of an intercepted call for retrieving information from said storing means selectively in accordance with said directory number, and means for generating an audio message in accordance with information retrieved from said storing means and for providing said audio message over said trunk circuit means to the calling party; means for providing personal signaling service relative to predetermined ones of Said selected directory numbers comprising, radio signal transmission means, and means responsive to the receipt of an intercepted call to one of said predetermined directory numbers for operating said intercepting means to enable said radio signal transmission means in a manner determined by information retrieved from said storing means in accordance with said directory number of said intercepted call.
Claim 8
Dependent Claim 169 words
In a telephone switching system including means for intercepting calls to selected directory numbers and for providing an audio message to the calling party; said intercepting means including trunk circuit means for receiving intercepted calls, means for storing information relative to said selected directory numbers, means utilizing the directory number of an intercepted call for retrieving information from said storing means selectively in accordance with said directory number, and means for generating an audio message in accordance with information retrieved from said storing means and for providing said audio message over said trunk circuit means to the calling party; means for providing personal signaling service relative to predetermined ones of Said selected directory numbers comprising, radio signal transmission means, and means responsive to the receipt of an intercepted call to one of said predetermined directory numbers for operating said intercepting means to enable said radio signal transmission means in a manner determined by information retrieved from said storing means in accordance with said directory number of said intercepted call.
