Metrobility Optical Systems introduced an Ethernet Network Interface Device (NID) that adheres to the IEEE 802.3ah draft standard for Ethernet in the First Mile (EFM) and conforms to the Metro Ethernet Forum’s Services Model for E-Line or point-to-point services. Metrobility said its new E-Services NID enables service providers to utilize existing Ethernet switches and routers at the customer site to offer Metro Ethernet services.
As the CPE demarcation point, the E-Services NID supports VLAN-aware bridging and provides MEF-compliant E-Line services. The solution consists of a Gigabit Ethernet Services Line Card mounted into Metrobility’s Radiance R5000, R1000, R400 or R200 chassis. The Services Line Card supports copper-to-fiber or fiber-to-fiber connectivity with 10/100/1000Mbps autonegotiation on the copper port. The fiber connectivity is provided using small form-factor pluggable (SFP) optics. Singlemode fiber connectivity can extend network distances up to 100km.
Metrobility’s E-Services NID monitors the health and status of devices and network connections, including remote optical link loopback testing, integral optical power monitoring, IEEE 802-compliant and RMON Group 1 statistics to determine quality of line, errored symbol and frame events. It also delivers real-time analog information for equipment power and temperature that provide “dying gasp” capabilities. The solution scales for a large metro access service deployment by eliminating the need for an IP address at each customer site. http://www.metrobility.com
