MERRIMACK, N.H. -- Metrobility Optical Systems, a next-generation optical networking company providing metro Ethernet connectivity, access, wavelength multiplexing and management solutions, today announced that it 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.

The 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 the industry’s most 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 of the R821 include the following, which enable service providers to deploy and manage Ethernet services to business and residential customers rapidly and cost effectively:

  • Metrobility’s multiple-level management approach provides flexibility in the management of Ethernet services. This approach 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 patent-pending 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 R821 also provides 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.

This sophisticated set of management tools enable network builders to realize dramatic reductions in the cost of management and higher revenue streams from new service offerings.

“The 10/100Mbps option is a natural evolution of our E-Services NID product line,” said Alex Saunders, president and CEO of Metrobility. “While we had many early adopters interested in our Gigabit E-Services NID, they also needed a 10/100Mbps solution. Based on customer feedback, there is no doubt that Ethernet in the First Mile will be a viable player for service providers looking to offer services which span voice, video and data. With the introduction of our new R821 E-Service NID, we continue on our path to provide network builders the management tools necessary to aid in the mass deployment of optical Ethernet services.”

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.
