Test Call Measurement to Access N-ISDN 64 KBITS/s Circuit- Switched Bearer Service UDI in Operation Series E: Overall Network Operation Telephone Service Service Operation and Human Factors Quality of Service Network Management and Traffic Engineering - N
This Recommendation describes methods for assessing in operation the serveability performance of setup, information transfer and disengagement phases of 64 kbitls circuit-switched ISDN connections and networks by means of test calls. Methods are given for determining the values of derived performance parameters fiom the primary measurements. The parameters themselves are, for the most part, defined in other Recommendations in the E-, G-, I-, M- and O-series.
