Abstract

This invention relates to a method for event signaling without establishing a data path connection in a communication network. The method steps include (a) setting up a dialing path through a network from one device (a server) to another device (a workstation), and (b) detecting a dialing (ringing) event by the server and either removing the path or taking other action. The other action includes propagating a no- connection signal to other equipment.

No-Connection Signal Method

This invention relates to a method for event signaling without establishing a data path connection in a communication network. The method steps include (a) setting up a dialing path through a network from one device (a server) to another device (a workstation), and (b) detecting a dialing (ringing) event by the server and either removing the path or taking other action. The other action includes propagating a no- connection signal to other equipment.

There are many devices available today which attach to a telephone system. One type of device is an automatic telephone answering machine which answers incoming telephone calls after some preset number of rings, plays a prerecorded audio message to the caller, beeps, and records any verbal message the caller cares to speak. Note that these devices complete the call (answer the phone) by achieving a circuit connection.

Other devices available today automatically place telephone calls. These range from automatic speed dialers to alarm systems. Here again, however, these devices automatically achieve a telephone connection with a remote device.

The no-connection signal method described herein is able to pass multivalued signals to a remote (answering) device without completing the telephone call. This function is achieved through the use of a ring event counter which keeps track of how many ring events are detected at the answering device. Thus, if only a single ring is detected, the answerin...
