System and method for switching a connection

1. A method for switching a connection between a first and a second terminal of a communications network, where switching occurs upon request from a source outside of the communications network, comprising:

connecting two time-slot-controlled inputs for transmission segments of a media gateway via a data line;

sending a CtD connection request from a CtD server to the media gateway such that the inputs connected with one another are configured for transmission of signals in a common time slot;

establishing a connection between a first of the inputs and the first terminal and a connection between a second of the inputs and the second terminal; and

switching the two connections together to form a transmission segment.

2. The method according to claim 1 , further comprising, before sending, determining availability of inputs connected in pairs for the transmission segments in a common time slot.

3. The method according to claim 2 , wherein the availability of inputs connected in pairs for the transmission segments is determined by time-cycle-controlled inquiry to the media gateway.

4. The method according to claim 3 , wherein the availability of inputs connected in pairs for the transmission segments is determined by querying availability data stored in a database.

5. The system of claim 1 , wherein a Web application, a SLAP protocol application, and the database application run on different servers linked to one another in a network.

6. A system for switching a connection between a first and second terminal of a communications network, comprising:

a media gateway connected with an IP network and has protocol functionality;

a CtD server communicating with the media gateway;

at least two inputs for transmission segments of the media gateway connected with one another via a data line; and

a database application in which current availability data of inputs connected in pairs for the transmission segments is stored in a common time slot on the media gateway.

7. The system according to claim 6 , wherein the CtD server communicates with the media gateway via a SLAP protocol application.

8. The system according to claim 7 , wherein the CtD server makes available a Web application, with an interface such that a subscriber can initiate a CtD connection request.

9. The system according to claim 8 , wherein the Web application communicates directly with the SLAP protocol application for signal transmission.

10. The system according to claim 6 , wherein signaling on the transmission segments proceeds on the basis of a standardized protocol.

11. The system of claim 6 , wherein a Web application, a SLAP protocol application, and the database application run on different servers linked to one another in a network.

12. A media gateway for switching of connections, comprising:

connecting two time-slot-controlled inputs for transmission segments of a media gateway via a data line;

sending a CtD connection request from a CtD server to the media gateway such that the inputs connected with one another are configured for transmission of signals in a common time slot;

establishing a connection between a first of the inputs and the first terminal and a connection between a second of the inputs and the second terminal; and

switching the two connections together to form a transmission segment.

13. The media gateway of claim 12 , wherein a Web application, a SLAP protocol application, and the database application run on different servers linked to one another in a network.
