Computer controlled test facility for a telecommunication switch
First Claim
1. An apparatus for testing a telecommunications switch in a telecommunications system that includes telephone devices connected to the switch and the apparatus, each telephone device including means for detecting signals sent from the switch, means for sending reply messages to the apparatus corresponding to the signals detected by the detecting means, means for receiving command messages from said apparatus, and means for generating signals sent to the switch corresponding to the command messages, the apparatus comprising:
- means operating under the control of a program for directly sending said command messages over a first communication channel to a selected one of said telephone devices, said generating means responding to said command messages by generating corresponding signals sent to the switch via a second communication channel;
means, operating under the control of a program and responsive to said means for sending reply messages, for directly receiving said reply messages over said first communication channel from said selected one of said telephone devices, said reply messages representing the status of parameters associated with said selected one based on signals sent via the second communication channel by the switch;
means operating under the control of a program for identifying a received reply message that is responsive to a predetermined one of a previously sent command message;
means operating under the control of a program for determining if the actual status of parameters represented by said identified reply message matches an anticipated status of said parameters corresponding to said one of the command messages, a match of the actual and anticipated status of said parameters indicates an anticipated, successful reaction by said selected one of the telephone devices to said one command message and hence indicates successful switch operation.

Abstract
A plurality of telephone devices responsive to computer commands are connected to a telecommunications switch. A computer controlled apparatus sends command messages to the telephone devices causing them to initiate conventional actions such as dialing. The apparatus receives reply messages from the telephone devices which represent the status of parameters such as ringing associated with the telephone device. Reply messages are identified relative to previously sent command messages. If the actual status of parameters represented by a reply message matches an anticipated status of the parameters corresponding to actions expected in response to a command message, a successful test of the switch functions associated with the command message results. An unmatched condition corresponds to a test failure requiring user analysis.

8. A method for testing a telecommunications switch in a telecommunications system that includes telephone devices connected to the switch, each telephone device including means for detecting signals sent from the switch, means for sending reply messages to the apparatus corresponding to the signals detected by the detecting means, means for receiving command messages from said apparatus, and means for generating signals sent to the switch corresponding to the command messages, the method comprising the steps of:
-
sending said command messages over a first communication channel directly to a selected one of the telephone devices, said generating means responding to said command messages by generating a corresponding signal sent to the switch via a second communication channel; directly receiving said reply messages over said first communication channel from said selected one of the telephone devices, said reply messages representing the status of parameters associated with said selected one based on signals sent via said second communication channel by the switch; identifying a received reply message that is responsive to a predetermined one of a previously sent command message; determining if the actual status of parameters represented by said reply identified message matches an anticipated status of said parameters corresponding to said one of the command messages, a determination of the validity of said match indicating a successful reaction by said selected one of the telephone devices to said one command message and successful switch operation. - View Dependent Claims (9, 10, 11, 12, 13)
