Process for transmitting data, in particular GSM data

A method of transmitting data between a calling subscriber and a called subscriber, using a predetermined frame format, comprising the steps of:

• subdividing a data stream between a first transcoder assigned to the calling subscriber and a second transcoder assigned to the called subscriber into a first data stream with samples for transmission and a second data stream with signal parameters for at least one of reconstructing user data and signaling, wherein the signal parameters are provided for transparent switching;
• simultaneously transmitting the first and second data streams as a function of predetermined operating conditions, wherein the data is GSM data;
• and
• transmitting identification information instead of the signal parameters for a predetermined period of time during a handshake phase between the calling subscriber and the called subscriber, wherein the step of transmitting identification information includes,
• transmitting only samples during the handshake phase, and
• inserting zero sequences instead of the signal parameters, wherein the zero sequences are inserted before the identification information.
