Abstract
Abstract The invention uses a suppressed ringing connection, switched through the existing call processing switch fabric, to connect between two customer premise equipments (CPEs) for long duration, low priority calls. The suppressed ringing connection is implemented such that the connection is disconnected if an incoming call to one of the CPEs or an outgoing request for service from one of the CPEs is made. If the suppressed ringing connection is disconnected due to a request for normal service to or from one of the CPEs, the system of the invention automatically reestablishes the suppressed ringing connection after the normal service call has ended such that the long duration suppressed ringing connection can be maintained on a quasi-permanent basis. As a result, the suppressed ringing connection can be maintained for long duration connections without disrupting normal incoming or outgoing service to either of the connected CPEs.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
A system for controlling connections in a telecommunications network comprising: a switching system for hosting a plurality of local lines and for switching calls to and from said local lines, customer premise equipment being connected to said lines; means for establishing a suppressed ringing connection over a selected one of said plurality of lines to a particular customer premise equipment connected to said selected one of said lines; means for disconnecting said suppressed ringing connection when a request for a regular connection over said selected one of said plurality of lines is made, said means for disconnecting operating in response to a service profile defining how the suppressed ringing connection is to be handled; and means for reestablishing said suppressed ringing connection when use of said regular connection is ended.
Claim 2
Independent Claim
130 words
A system for controlling connections in a telecommunications network comprising: a switching system for hosting a plurality of local lines and for switching calls to and from said local lines, customer premise equipment being connected to said lines; means for establishing a suppressed ringing connection over a selected one of said plurality of lines to a particular customer premise equipment connected to said selected one of said lines; means for disconnecting said suppressed ringing connection when a request for a regular connection over said selected one of said plurality of lines is made, said means for disconnecting operating in response to a service profile defining how the suppressed ringing connection is to be handled; and means for reestablishing said suppressed ringing connection when use of said regular connection is ended.
Claim 3
Dependent Claim
15 words
The system of claim 1, wherein said particular customer premise equipment constitutes a medical device.
Claim 4
Dependent Claim
16 words
The system of claim 1, wherein said particular customer premise equipment constitutes a processor controlled appliance.
Claim 5
Dependent Claim
30 words
The system of claim 1, wherein the means for establishing a suppressed ringing connection includes a central office service unit capable of establishing a plurality of suppressed ringing connections simultaneously.
Claim 6
Dependent Claim
17 words
The system of claim 1, wherein a calling unit is connected to the particular customer premise equipment.
Claim 7
Dependent Claim
27 words
The system of claim 5, wherein the means for reestablishing includes means, controlled by said calling unit, for periodically requesting that the suppressed ringing connection be established.
Claim 8
Dependent Claim
33 words
The system of claim 1, wherein said means for disconnecting includes means for identifying the suppressed ringing connection as low priority, said means for disconnecting operating in response to said means for identifying.
Claim 9
Dependent Claim
49 words
The system of claim 1, wherein said means for reestablishing includes means for monitoring the status of the selected one of the local lines after the means for disconnecting disconnects said suppressed ringing connection, said means for monitoring recognizing when said selected one of the local lines becomes idle.
Claim 10
Dependent Claim
23 words
The system of claim 1, wherein the service profile is variable such that the handling of the suppressed ringing connection can be varied.
Claim 11
Independent Claim
160 words
A system for controlling connections in a telecommunications network comprising: a switching system for hosting a plurality of local lines and for switching calls to and from said local lines, customer premise equipment being connected to said lines; means for establishing a suppressed ringing connection over a selected one of said plurality of lines to a particular customer premise equipment connected to said selected one of said lines; means for disconnecting said suppressed ringing connection when a request for a regular connection over said selected one of said plurality of lines is made including an advanced intelligent network (AIN) for providing a disconnect signal to said switching system for controlling disconnection of said suppressed ringing connection in response to a trigger hit by the request for said regular connection; and means for reestablishing said suppressed ringing connection when use of said regular connection is ended including a means for sending a reestablish signal from said AIN to said switching system.
Claim 12
Independent Claim
160 words
A system for controlling connections in a telecommunications network comprising: a switching system for hosting a plurality of local lines and for switching calls to and from said local lines, customer premise equipment being connected to said lines; means for establishing a suppressed ringing connection over a selected one of said plurality of lines to a particular customer premise equipment connected to said selected one of said lines; means for disconnecting said suppressed ringing connection when a request for a regular connection over said selected one of said plurality of lines is made including an advanced intelligent network (AIN) for providing a disconnect signal to said switching system for controlling disconnection of said suppressed ringing connection in response to a trigger hit by the request for said regular connection; and means for reestablishing said suppressed ringing connection when use of said regular connection is ended including a means for sending a reestablish signal from said AIN to said switching system.
