Telecommunication networks have become fundamental for our daily life, and their outages can bear large consequences and customers' economic loss. The importance of telecommunication network reliability is demonstrated by the large body of literature, but unfortunately reliability analysis of the network from customer damage perspective is scarce. To fill this gap, this paper analyses two key techniques to assess the reliability of a network. A review of reliability metrics and customer damage functions is given. The reliability metrics of telecommunication networks are summarized according to the network development. Furthermore, customer damage functions for several sectors are also categorized into six groups to cover the parties affected and various usage scenarios. We believe that this work represents an important point for academy and industry to understand and contribute to the area of telecommunication network reliability.

Keywords: Telecommunication network, Reliability analysis, Reliability metrics, Customer damage function, Outage loss.
