As a carrier-class device, the Metrobility R861 Services Line Cards for Ethernet by Telco Systems provide an intelligent optical Ethernet CPE demarcation point for service providers who are deploying Ethernet in the First Mile. The R861 Services Line Cards are specifically designed to maintain the maximum isolation between the public and private network while offering the Operations, Administration and Maintenance (OAM) aspects of the IEEE 802.3ah standard as defined by both the IEEE and the Metro Ethernet Forum (MEF). These OAM management features provide loopbacks, MIB statistics, errored frame events, and “Dying Gasp” capabilities. These features allow keep-alives for transparent service monitoring.

The R861 Services Line Cards supports delivery of E-Line services. Traffic belonging to each service is classified by, and tunneled over, pre-determined VLANs for segregation and transport across carrier networks. Controlled at the Services Line Cards, VLANs identify and segregate the specific ISP-access or corporate-access E-Line service. Proxy-based Management is via the Metrobility NetBeacon ESP Element Manager.
