Official abstract text for this publication.
System and method for detecting and reporting an error in communications with customer premise equipment. A preferred embodiment comprises monitoring the communications link between an access device and customer premise equipment located on customer premises. If a communications link fails, or some other condition occurs, an error signal is transmitted to the access network to notify downstream network elements of the error condition. In one embodiment, an access device is communicatively coupled to a demarcation device via an Ethernet link. If a loss of link occurs on the Ethernet link, an error signal, such as an alarm indicator signal, is transmitted through the network.
Opening claim text (preview).
What is claimed is: 1. An access device comprising: a processor; a first port configured for communicatively coupling to a demarcation device via an Ethernet link; a second port configured for communicatively coupling to an add/drop multiplexer (ADM) via a DS-3 communications link, wherein the ADM separates traffic on the DS-3 link from, and integrates onto, the Ethernet link; and a processing unit configured to monitor the first port and to generate an alarm signal on the s…
