The terms "customer" and "service" are used synonymously when describing a service implementation on the Nokia 7750 SR.

Within Nokia service routers, “customer” identifies the administrative owner of a set of services, while “service” defines the actual connectivity construct (IES, VPLS, VPWS, etc.). The two terms are distinct and not interchangeable.

A – Treating the two terms as synonymous would ignore the administrative separation between customer context and service instance.
