Nosaukums<p>This International Standard specifies the signalling protocol for the support of the Call Identification and Call Linkage</p> <p>Additional Network Feature (ANF-CIDL) at the Q reference point between Private Integrated Network Services Exchanges</p> <p>(PINXs) connected together within a Private Integrated Services Network (PISN).</p> <p>ANF-CIDL is an additional network feature which allows the assignment of a Global Call Identification (GID) to identify a</p> <p>call end-to-end over the call route (i.e. between the two end PINXs). As an option, a Thread Identification (TID) may be</p> <p>assigned to different calls which are logically linked together due to the operation of other supplementary services and/or</p> <p>ANFs. Additionally a Leg Identification (LID) may be assigned, to identify the different legs of a call.</p> <p>NOTE 1 - This ANF has been developed to support the use of CSTA (ISO/IEC 18051) in a networked environment, i.e. in a PISN. Use of</p> <p>this ANF for other applications is not precluded.</p> <p>The Q reference point is defined in ISO/IEC 11579-1.</p> <p>Supplementary Service specifications are produced in three stages and according to the method specified in ETS 300 387.
