Abstract

The invention relates to an arrangement for connecting an optical waveguide to a microprocessor-controlled electrical appliance having an arithmetic module which is connected to the electrical appliance and has network functionalities for linking the electrical appliance to a network, an interface chip, connected to the arithmetic module, in the form of an integrated circuit chip, and an optical transmission and reception chip which is connected firstly to the interface chip and secondly to the optical waveguide. In order to make such an arrangement particularly efficient, provision is made for the interface chip to have integrated functional modules which provide at least some of the network functionalities.

Claims

1. A method for signaling an instruction to modify coding of a user data connection section termination of a media gateway from a media gateway controller to the media gateway, comprising signaling an instruction from the media gateway controller to the media gateway that verification of the connectability of terminations is implemented after receipt of a plurality of instructions to modify the coding of at least one termination.

2. The method according to claim 1, where the media gateway no longer transmits user data from and to a relevant termination once it has received a modification instruction for this termination, until the specified verification of the connectability of terminations has taken place.

3. The method according to claim 1, wherein the media gateway receives an instruction from the media gateway controller to hold the verification of the connectability of terminations until the media gateway receives at least one instruction from the media gateway controller to modify the coding of another connected termination.

4. The method according to claim 1, wherein the media gateway starts the verification when it has received instructions for the connected terminations to modify the terminations.

5. The method according to claim 1, wherein the media gateway starts the verification when it receives an instruction to start the verification of the connectability of terminations.

6. The method according to claim 1, wherein the instruction to hold the verification of the connectability of terminations is signaled to the media gateway in a message, in which the media gateway is informed that it should modify the coding for at least one termination at the media gateway.

7. The method according to claim 1, wherein the MGW does not isolate the relevant termination immediately after receipt of the modification instruction from the MGC but waits until switching of the coding is prompted via a subsequent separate signaling with the switching node at the other end of the user connection section.

8. The method according to claim 1, wherein the MGW does not restore the connections immediately after the verification but waits until switching of the coding at the terminations has also been prompted via separate signaling with the switching node at the other ends of the user connection sections to be reconnected.

9. The method according to claim 1, wherein the MGW reconnects the originally connected terminations in their old coding, if the MGW determines during the verification that it cannot connect the terminations to each other in their new coding.

10. The method according to claim 1, wherein the MGW transmits an error message to the MGC in response to the instruction to modify the last termination and the MGC then uses mechanisms existing in BICC, Q.1902.4, to reject the modification of the user connections.

11. The method according to claim 1, wherein an extension of existing instructions to modify a termination is used as the voice element for an instruction to hold the verification.

12. The method according to claim 10, wherein the voice element is a characteristic of the so-called H.248 context.

13. The method according to claim 10, wherein the voice element is a characteristic of the so-called H.248 termination.

14. The method according to claim 10, wherein the MGC isolates a termination by means of a specific instruction, before the MGC modifies the coding at said termination and after the MGC has also modified the coding at one or a plurality of other originally connected terminations, the MGC reconnects the isolated termination by means of a further specific instruction.

15. The method according to claim 10, wherein the MGC isolates a termination by moving it to another so-called H.248 context.

16. The method according to claim 10, wherein the MGC uses the so-called Q.1950 instructions “

Isolate” and

“

Join”

.

17. The method according to claim 10, wherein a termination is a termination of a user data connection section of the telecommunication network, which ends at the media gateway.

18. A device for signaling an instruction to modify coding of a user data connection section termination of a media gateway from a media gateway controller to the media gateway, with an instruction being signaled from the media gateway controller to the media gateway that verification of the connectability of terminations is implemented after receipt of a plurality of instructions to modify the coding of at least one termination.

19. A method for signaling an instruction to modify coding of a user data connection section termination of a media gateway from a media gateway controller to the media gateway, comprising signaling an instruction from the media gateway controller to the media gateway that verification of the connectability of terminations is implemented after receipt of a plurality of instructions to modify the coding of at least one termination, wherein the media gateway no longer transmits user data from and to a relevant termination once it has received a modification instruction for this termination, until the specified verification of the connectability of terminations has taken place.
