Abstract
An enhanced data communication node is disclosed. The data communication node can be coupled to a local area network and a wide area network for transferring data traffic between the two networks according to a first protocol, for example, a frame relay protocol. The data communication node includes a network reporting element capable of monitoring management information of an intermediate network coupled into a data communication path to the wide area network. The management information includes service level information of the intermediate network and equipment fault information of a bridging device coupled to the data communication node and the intermediate network. The bridging device encapsulates data according to a second protocol, for example, a Digital Subscriber Line (DSL) protocol. The encapsulating is transparent to the transfer of data between the local area network and the wide area network by the data communication node.
