适用范围

This is a Recommendation on network performance. It covers the connection access phase for all network conditions from normal operation over degraded operation to unavailable states’). It provides measures and objectives for accessibility performance of international circuit switched 64 kbit/s ISDN connection types (see Table 2A.340: AI, A4, A7) between T-reference points. It covers effects of traffic load, failures, operational actions (planned and unplanned), etc. It does not cover blocking because of lack of channels at T-reference points nor catastrophic situations, e.g. earth quakes, floods, etc. It only covers connections which are all the way within ISDNs.
