    Launching New Work ProgrammePSTN/ISDN simulation serviceITU-T Rec. Q.2211 defines OIP, OIR, TIP, TIR, MCID, ACR, CDIV, HOLD, CB, CCBS, CW, MWI, CONF, AOC, ECT, RC, UPT, CRBT, CRTProcess to develop protocol specificationsStep 1: Define the target of PSTN/ISDN simulationservices to develop service protocol specificationsStep 2: Define the reference base specification of other SDOs (ex. TISPAN, 3GPP)Step 3: Modify base reference specifications and adjust them to ITU-T requirements and architectures, etc

    Detailed protocol specifications of global standard are needed to achieve interoperability
