Abstract

In a telephone exchange system accommodating a large number of communication lines, a line status display system is provided, which permits display of the status of a large number of lines in a limited display space of the terminal for scale reduction, is capable of flexible use with satisfactory operation control property and will not reduce the processing capacity of the exchange equipment. In a telephone exchange system comprising an exchange equipment (1) and a plurality of terminals (2, 2'"'"') accommodated therein, the exchange equipment (1) accommodating a plurality of lines, when detecting a line status change, sends out corresponding information to all the terminals (2, 2'"'"'), and the terminals check whether the line is a subject of processing, and if so, displays pertinent information in a predetermined display position.

Claims

1. A line status display system for a telephone exchange system, comprising:

an exchange apparatus containing a plurality of lines; and

a plurality of terminals respectively connected to said exchange apparatus, said terminals displaying and controlling said line status in association with said exchange apparatus,

wherein said exchange apparatus includes control means for simultaneously informing all of said terminals of line status information including status of said lines and line identification information for identifying said lines,

wherein each of said terminals include,

a memory for storing a line status display table for controlling the line identification information relating to a line which is responsive to a one-touch manual operation in said plurality of lines contained in said exchange apparatus, and for storing the line identification information relating to a line which is responsive to an operation other than said one-touch manual operation in said plurality of lines contained in said exchange apparatus,

a first status display means provided corresponding to the line which is responsive to said one-touch manual operation,

a second status display means provided corresponding to the line which is responsive to said operation other than said one-touch manual operation,

a recognition means for referring to the line identification information of said line status information informed from control means of said exchange apparatus on the basis of said line status display table when said line status information is informed from said control means of said exchange apparatus, and for recognizing whether a line corresponding to the referred line status information is responsive to said one-touch manual operation, or whether the line corresponding to the referred line status information is responsive to said operation other than said one-touch manual operation; and

a display control means for displaying and controlling the status of the line corresponding to the line status information on the first status display means when said recognition means recognizes that the line is responsive to said one-touch manual operation, and for displaying and controlling the status of the line corresponding to said line status information on the second status display means when said recognition means recognizes that the line is responsive to said operation other than said one-touch manual operation.

2. The line status display system for a telephone exchange system according to claim 1, wherein the status of the line included in said line status information is one of a void, incoming call, answering, or holding status.

3. The line status display system for a telephone exchange system according to claim 2, wherein said each of said terminals further comprises:

a third status display means for displaying that a line responsive to said operation other than said one-touch manual operation is in said holding status, and

means for displaying and controlling the status of the line corresponding to the line status information of said holding status on the third status display means when the line status of line status information is in said holding status and a line corresponding to said line status information is responsive to said operation other than said one-touch manual operation.

4. The line status display system for a telephone exchange system according to claim 2, wherein said each of said terminals includes:

display means for displaying character information,

means for changing line identification information related to a line responsive to said operation other than said one-touch manual operation to character information, and

means for list-displaying character information corresponding to the line identification information on said display means in order to list-display character information corresponding to a line in said holding status with other lines related to said operation other than said one-touch manual operation based on an order of when lines are placed into said holding status.

5. The line status display system for a telephone exchange system according to claim 4, wherein said each of said terminals further includes means for deleting character information corresponding to the line responsive to said operation other than said one-touch manual operation when the line status information of the line related to said operation other than said one-touch manual operation is in said answering status and the display means displays the status of the line as said holding status.

6. The line status display system for a telephone exchange system according to claim 1, wherein said each of said terminals comprise:

display means for displaying character information;

means for changing line identification information related to a line responsive to said operation other than said one-touch manual operation to character information; and

means for list-displaying character information corresponding to said line identification information on said display means.

7. The line status display system for a telephone exchange system according to claim 1, wherein said each of said terminals comprise:

display means for displaying character information;

means for changing line identification information related to a line responsive to said operation other than said one-touch manual operation to character information; and

means for list-displaying character information corresponding to said line identification information on said display means in order to list-display character information corresponding to a line of an incoming call with other lines related to said operation other than said one-touch manual operation based on an order of incoming calls.

8. The line status display system for a telephone exchange system according to claim 7, wherein said each of said terminals have answering means for selecting a line of an incoming call displayed on said display means and answering the line of said incoming call.

9. The line status display system for a telephone exchange system according to claim 7, wherein said each of said terminals further includes means for deleting character information corresponding to the line responsive to said operation other than said one-touch manual operation when the line status information of the line related to said operation other than said one-touch manual operation is in said answering status and the display means displays the status of the line as said incoming call status.
