Network Effectiveness Ratio (NER)
In telecommunications, the Network Effectiveness Ratio (NER) measures the ability of a network to deliver a call to the called terminal. Busy signals and other call failure due to user behaviour are counted as "successful call delivery" for NER calculation purposes. Unlike ASR, NER excludes the effects of customer and terminal behaviour.
The NER is a measure of network quality defined in ITU-T Recommendation E.425.
