ABSTRACT:
A network environment including a provider network coupled to a first customer network site via a first access link and to a second customer network site via a second access link. The provider network is operable with the IEEE 802.1ag standard for propagating a remote link fault condition via an Ethernet Alarm Indication and Suppression (AIS) frame or a Continuity Check (CC) frame, which is translated into a locally compliant non-IEEE 802.1ag error delivery condition so that a management entity associated with the first customer network site is appropriately alerted.
