PROCEDURES FOR ESTABLISHING AND CONDITIONING A SIMILAR TRANSFER MODE ON A TELECOMMUNICATION NETWORK, AND TO UNIT INFORMATION ON CONTROL OF CALLING AND INFORMATION IN THE SIGNIFICATION OF CONTROL OF TYPE 2(AAL2) OF ATM CONTROL ON A TELECOMMUNICATION NETWORK"ON A Transmission Network based on asynchronous Transfer Mode (ATM),call control signaling information associated with a first telecommunications signalling protocol, such as N-ISDN system 7 signalling protocol, is united to carrier control signalling information associated with a Q.aa12 signalling protocol,where both call control signalling information and carrier control signaling information are required to establish and maintain an ATM network connection. Union of call control signalling information and carrier control signaling information is carried out as a function of the circuit identification code associated with call control signalling information,where the circuit identification code is transferred from system 7 signal protocol of N-ISDN to the Q.aa12 signalling protocol. Call control signalling information and carrier control signalling information are then transported independently of a source node in the transmission network to a destination node, through a Type 5 adaptation layer link of ATM/ATM, according to the signalling protocol system 7 of ISUP and the Q.aa12 signalling protocol respectively. In the knot of fate,Call control signal information and carrier control signaling information are aligned as a circuit identification code function, and an ATM network connection is established.
