Claim:
A method of transmitting signaling data, which relates to a telephone connection having both signaling data and message content parts, said signaling data conforming to the ISDN standard and being transmitted on a first channel that conforms to the UDP-IP standard and does not conform to the ISDN standard, which method is characterized in that it includes the following steps: converting said signaling data in the format of the ISDN standard into data in a format accepted by the first channel, sending the signaling data converted in this way over said first channel, and when it is received, converting the signaling data reciprocally into signaling data conforming to the ISDN standard format, said method being further characterized in that: the signaling data to be transmitted is formatted into successive data blocks, send blocks are constructed from said successive signaling data blocks by adding to them information on the order of the blocks, the send blocks are sent from a unit connected to one end of the first channel, the send blocks are received in another unit connected to the other end of the first channel, send blocks that have been received are tested in said another unit, and said other unit sends an acknowledgment signal (n) designating the highest numbered send block that has been received and belongs to a continuous series of send blocks.
