Abstract
Abstract A telephone for use in ISDN telephone systems that implement advanced features such as call forwarding and a method for operating an ISDN telephone system to provide such advanced features are provided for. In an ISDN telephone system implementing the invention, the telephone communicates commands to the switching system by sending codes to the switching system. These codes normally denote keys on the telephone that have been depressed by a user of the telephone. A user of the advanced telephone features having a conventional telephone signals the switching system to activate the advanced telephone feature by depressing a specific key on the conventional telephone. In a system according to the present invention, a code having a value greater than any key code in any telephone in the telephone system is defined and an advanced telephone feature is assigned to that code thereby causing the switching system to implement that advanced feature when the switching system receives that code from a telephone over the network. A telephone according to the present invention includes a menu system that allows the user to select the advanced features implemented by the telephone system. The controller also includes a communication program that causes the switching system to download a list of advanced features implemented by the switching system, and the controller creates a menu item corresponding to each advanced feature identified in the list. In one embodiment of the present invention, the controller implements programs that simplify the use of the advanced features.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
In a method for operating an ISDN telephone system including a set of telephones that communicate with a switching system via a telephone network using a first set of codes, said codes normally denoting keys that have been pressed by a telephone user, said tone system implementing a set of advanced telephone features, a user signaling said switching system to activate one of said advanced telephone features by pressing a specific key on a telephone in said set, the improvement comprising: defining a second set of codes at the switching system, each code in said second set having a value greater than all codes in said first set; and assigning said one of said advanced telephone features to one of said defined codes thereby causing said switching system to implement said advanced feature when said switching system receives said one of said defined codes from a telephone over said network.
Claim 2
Dependent Claim
150 words
In a method for operating an ISDN telephone system including a set of telephones that communicate with a switching system via a telephone network using a first set of codes, said codes normally denoting keys that have been pressed by a telephone user, said tone system implementing a set of advanced telephone features, a user signaling said switching system to activate one of said advanced telephone features by pressing a specific key on a telephone in said set, the improvement comprising: defining a second set of codes at the switching system, each code in said second set having a value greater than all codes in said first set; and assigning said one of said advanced telephone features to one of said defined codes thereby causing said switching system to implement said advanced feature when said switching system receives said one of said defined codes from a telephone over said network.
Claim 3
Dependent Claim
43 words
A method of claim 1 in which a table is used to map one code from said first Set of codes to one code from said second set, said code from said second set being forwarded to said switch to implement said feature.
Claim 4
Dependent Claim
216 words
An ISDN telephone comprising: a plurality of keys, each of said keys generating a code from a first set of codes upon being pressed by a user of said ISDN telephone, said code from first set identifying the key from which it was generated, said code from said first set being sent on a telephone line connected to said telephone, at least one code from said first set of codes activating an advanced feature; and a controller including a mean for receiving a second set of codes at a switching system connected to said telephone and a memory for storing said second set of codes, at least one of said codes in said second set corresponding to said advanced feature to be activated by the switching system, said code in said second set corresponding to said advanced feature having a value greater than all codes in said first set; and display means for displaying a menu comprising a plurality of items to a user and for receiving input from said user identifying one of said items, wherein one item on said menu corresponds to said advanced feature and wherein said code in said second set of codes corresponding to said advanced feature is sent to said switching system in response to said user identifying said item.
Claim 5
Dependent Claim
216 words
An ISDN telephone comprising: a plurality of keys, each of said keys generating a code from a first set of codes upon being pressed by a user of said ISDN telephone, said code from first set identifying the key from which it was generated, said code from said first set being sent on a telephone line connected to said telephone, at least one code from said first set of codes activating an advanced feature; and a controller including a mean for receiving a second set of codes at a switching system connected to said telephone and a memory for storing said second set of codes, at least one of said codes in said second set corresponding to said advanced feature to be activated by the switching system, said code in said second set corresponding to said advanced feature having a value greater than all codes in said first set; and display means for displaying a menu comprising a plurality of items to a user and for receiving input from said user identifying one of said items, wherein one item on said menu corresponds to said advanced feature and wherein said code in said second set of codes corresponding to said advanced feature is sent to said switching system in response to said user identifying said item.
Claim 6
Dependent Claim
49 words
The ISDN telephone of claim 3 wherein said controller further comprises means for causing said switching system to download a set of advanced features implemented by said switching system, and wherein said controller creates said menu item corresponding to each advanced feature identified in said set of advanced features.
Claim 7
Dependent Claim
40 words
The ISDN telephone of claim 4 wherein said controller determines if an advanced feature is supported by said switching system by displaying said set of advanced features to a user of said telephone and receiving a response from said user.
Claim 8
Dependent Claim
67 words
The ISDN telephone of claim 3 wherein said controller further comprises means for executing a program comprising a plurality of codes from said second set of codes that are sent to said switching system in response to said user selecting one of said items on said menu, at least two of said codes corresponding to a respective one of said advanced features implemented by the switching system.
Claim 9
Dependent Claim
15 words
The ISDN telephone of claim 6 wherein one of said advanced features comprises conference calling.
Claim 10
Dependent Claim
33 words
The telephone of claim 3 in which said second set of codes includes a code that is display if and only if the controller determines that the switch supports a corresponding advanced feature.
