Abstract

An improved technique for connecting calls through a telephone network is disclosed wherein a data signal transmitted from a computer over- a separate network is used to instruct the telephone switch to make the desired connection.

Claims

1. In a communications system having a telephone network and a separate second network, a method of completing a telephone call from a calling terminal having a first telephone number to a called terminal having a second telephone number via a switch over the telephone network, the switch having a first address on said separate second network and a second address on said telephone network, comprising:

transmitting over said separate second network using said first address to said switch, a single request for said call from said calling terminal, said request including both said first telephone number and said second telephone number;

selecting, at the calling terminal, which of said first or second numbers should be dialed first;

sending information indicative of which of said first or second telephone numbers should be dialed first from the calling terminal to said switch over said second network;

receiving, at the switch, said request and said information;

forming a connection between said calling terminal and said called terminal through said telephone network in response to said request and said information by dialing said first telephone number and said second telephone number in an order as selected at said calling terminal.

2. The method of claim 1 wherein said transmitting is performed from a personal computer.

3. The method of claim 2 wherein said personal computer is connected to both a data network and a telephone network.

4. The method of claim 2 further comprising the steps of:

transmitting a message from said switch to said personal computer; and

displaying on said personal computer information indicative of the state of the called telephone.

5. A method of completing a telephone call from a first terminal having a first telephone number to a second terminal having a second telephone number comprising:

transmitting over a data network from said first terminal digital signals including both said first telephone number and said second telephone number to at least two switches at different locations, the digital signals instructing each switch to establish a telephone connection to said first terminal and said second terminal respectively;

selecting, at said first terminal, which of said two telephone numbers should be dialed first;

sending information indicative of which of said first or second telephone numbers should be dialed first from the calling terminal to said two switches over said data network;

forming said each telephone connection in an order as selected at said first terminal; and

connecting the two switches via a telephone network.

6. The method of claim 5 wherein said step of transmitting comprises transmitting at least one of said digital signals from at least one of said switches to at least a second one of said switches.
