               NOTE: For the following subclauses, a cross-reference table would be helpful. However, it requires detailed
               information on the way a DFS service is using these underlying services. Also a description of the role of the
               respective basic technology in a DFS transaction is missing (or a reference to a new section, as suggested).
               Example: A DFS transaction is made of a couple of usages of some basic services of functions. For those
               functions, KPI definitions may exist. With the current structure, there is no information how far a DFS
               implementation is covered. For example: DTMF. A DFS transaction based on DTMF needs a connection set-up
               (telephony? Currently not covered; telephony is again treated by existing standards e.g. TS 102 250/E.804).


               C.2.1  SMS
               The following is a non-exhaustive list of technical KPIs which may be applied for SMS:

               •    Recommendation ITU-T E.804 (subclause 7.4.4):

                    •  SMS service non-accessibility [%]
                    •  SMS access delay [s]
                    •  SMS completion failure ratio [%]
                    •  SMS end-to-end delivery time [s]

                    •  SMS receive confirmation failure ratio [%]
                    •  SMS receive confirmation time [s]

                    •  SMS consumed confirmation failure ratio [%]
                    •  SMS consumed confirmation time [s]
               •    Recommendation ITU-T G.1040
                    •  Network contribution to total transaction time (in case the network is not packet based, the principles
                       laid out in G.1040 can be applied in analogy)
               •    3GPP TS 23107

                    •  Traffic class

               C.2.2  IVR

               The following is a non-exhaustive list of technical KPIs which may be applied for IVR:

               •    Recommendation ITU-T G.1040
                    •  Network contribution to total transaction time (in case the network is not packet based, the principles
                       laid out in G.1040 can be applied in analogy)
               •    Recommendation ITU-T P.863
                    •  Perceptual objective listening quality assessment
               •    No Recommendation currently available

                    •  Intellegibility, voice recognition

               C.2.3  DTMF

               The following is a non-exhaustive list of technical KPIs which may be applied for DTMF:

               •    ES 201 235
                    •  DTMF characteristics
               •    Recommendation ITU-T G.1040
