Abstract: Methods and systems for identifying communication circuits are disclosed. In particular a communication circuit communicatively couples a first node to a second node. A virtual circuit identification is then obtained based on a first address associated with the first node and a second address associated with the second node. The communication circuit is then identified based on the virtual circuit identification.

Abstract: A method and system for provisioning a Resilient Packet Ring (“RPR”) over a Wavelength Division Multiplexing (“WDM”) network is disclosed. A plurality of stations send data packets to each other over a dual ring fiber optic link. The data packets travel over the dual ring fiber optic link at a unique wavelength to distinguish the different data packets. When one station of the plurality of stations detects a location of a failure in the WDM network, the station identifying the location of the failure either notifies all stations of the plurality of stations of the location of the failure or notifies only the stations of the plurality of stations abutting the location of the failure. If all stations of the plurality of stations are notified of the failure, all stations steer data packets sent towards the location of the failure away from the location of the failure.

Abstract: A simplified field testing tool integrates signal-strength and error-rate testing for a variety of networking technologies prevalent for home networking, including but not limited to Multimedia over Coax (or applicable coax standard), HomePNA 2, VDSL, 10OBaseT Ethernet, 802.11 Wi-Fi, and analog/coaxial RF signals.

Abstract: A system and method are disclosed for transporting data including a first add drop multiplexer (ADM) configured to receive non Time Division Multiplexing (non-TDM) traffic and to encapsulate the non-TDM traffic as an embedded payload within a SONET synchronous transport signal (STS) frame. A first synchronous optical network (SONET) ring may be coupled to the first ADM and an optical cross connect module may at least partially interconnect the first SONET ring and a second SONET ring. The optical cross connect module may be configured to pass the SONET STS frame, having an embedded non-TDM data as a payload, to the second SONET ring without de-encapsulating the non-TDM traffic from the SONET STS frame. The ADM may be capable of converting data formats that comply with Open System Interconnection (OSI) layers 2, 3, and 4 into an STS format.

Abstract: A method of deploying a synchronous optical network (SONET) terminal is provided. The SONET terminal includes a management interface and an Ethernet port. A layer 2/3 data switch is connected to the management interface and the Ethernet port. Data associated with the SONET terminal is received at the layer 2/3 data switch. Further, the management data from the SONET terminal is converted from STS-1 data to DSx data at the layer 2/3 data switch. In a particular embodiment, the DSx data is routed to a DS1 channel within the SONET terminal. Also, the converted management data is transported over a data network as part of a SONET signal payload.
