View source for User–network interface

In [[telecommunications]], a '''user–network interface''' ('''UNI''') is a [[demarcation point]] between the responsibility of the service provider and the responsibility of the subscriber.  This is distinct from a [[network-to-network interface]] (NNI) that defines a similar interface between provider networks.
