Metrobility Optical Systems has expanded its E-Services Network Interface Device (NID) product line to include 10/100Mbps support as well as the ability to support rate limiting, Q-in-Q tagging and four service classes for traffic prioritization.
Metrobility's new R821 10/100 E-Services NID consists of a 10/100BASE-T user port and 100Mbps optical network port to create a secure customer premise equipment (CPE) demarcation point for point-to-point optical Ethernet services in metro area networks. The device offers an extensive set of operations, administration and maintenance (OAM) management options through a multi-level management approach for complete, end-to-end management of Ethernet services.
The management and trouble shooting capabilities include the following:
- a multiple-level management approach that enables service providers to manage the device as an independent network interface device with its own IP address using IP PING or SNMP, without an IP address using another IEEE802.3ah-compliant device, or in a back-to-back configuration without an IP address with Metrobility's NetBeacon Element Manager Software.
- as a Layer 2 device, service providers can adjust bandwidth and assign VLANS and up to four service classes on a per port basis to simplify installation and reduce start-up costs.
- intelligent management access controls make the device impervious to denial of service attacks under all traffic conditions and traffic patterns.
- a unique logical services loopback feature provides end-to-end service level verification across multiple providers to support individual service level agreements.
- troubleshooting tools include optical power monitoring, quality of equipment monitoring, and quality of line monitoring to enable fast fault identification and minimize the need for expensive truck rolls.
- the ability to test the copper line quality between the NID and the customer equipment to locate any link problems to the subscriber's network.
The E-Services NID consists of a NEBS Level 3 certified E-Services Line Card which is housed in a Metrobility chassis. Metrobility offers a choice of chassis options ranging from a 17-slot, 2-slot and 1-slot units with optional redundant AC or DC power. Fiber optic connectivity is provided with small form-factor pluggable (SFP) optics on the network port which offers flexible multimode, singlemode, single-strand and CWDM connectivity options.

- Early in 2004, 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.
