The Metrobility® Access Line Cards provide the ability to reach across a metropolitan area network to communicate, test and reconfigure an unmanaged remote device, without reducing the available bandwidth to the customer site. These devices provide a high level of manageability — including dynamic bandwidth provisioning, remote loopback testing, real-time analog and RMON statistics. The Access Line Card gathers real-time data to provide critical, up-to-the-minute Quality of Line information on an Ethernet fiber link including optical receive power level measurement, optical transmit power level measurement, and Radiance voltage and temperature measurements.

The Metrobility RA21 Optical Network Unit (ONU) from Telco Systems® provides a copper-to-fiber service demarcation point at the customer premise for the delivery of optical Ethernet services. The ONU communicates to a R231 Access Line Card in a managed Metrobility chassis at the central office.

This patented technology (U.S. Patent NO. 6,741,566 B1) utilizes a management channel embedded in the inter-packet gap (IPG) between Ethernet frames to send management information in real time across a network between two Access Line Cards or between an Access Line Card and an RA21 Optical Network Unit. The ONU communicates to a R231 Access Line Card in a managed Metrobility chassis at the central office.

Utilizing this technology, the service provider can reach across a metropolitan area network to communicate, test and reconfigure the Access Line Card or the RA21 ONU, without reducing the available bandwidth to the customer site, and without managing an additional IP address.

The innovative access line card technology does not require an IP address, or an SNMP software stack at each service subscriber (CPE), which greatly simplifies the installation. Because an IP address is not required at every access point, this solution 'scales' extremely well for large metro access service deployment, which could otherwise require the management of thousands to tens of thousands of IP addresses by the service provider. Further, network security is improved since no IP address exists to be 'attacked'.

Access Line Cards are supported in the Metrobility R5000, R1000 or R400 chassis and require an R502-M Management Card and NetBeacon 3.01 or above for reporting.

The Metrobility Ethernet interface products offer versatile speed, media, distance, and redundancy options to cost-effectively distribute fiber optic connections. These units provide seamless connectivity within the LAN, or between the LAN and public or private networks. The Metrobility R111 and 2111 preconfigured media converters offer transparent integration of fiber optic connectivity or copper-to-coaxial integration for 10Mbps Ethernet networks.

These mixed-media devices are available as interface line cards or standalone units for flexibile integration into your network. The interface line cards are supported in all Metrobility's chassis and can be managed when configured with a R502-M management card in select chassis. The standalone options utilize a rugged fabrication to offer superior reliability for the most demanding environments. Each standalone is equipped with an external, universal AC power supply.

The Metrobility® R141 line card and 2141 standalone are transparent two-port, copper-to-fiber media converters that can be set to either 10Mbps on both ports or 100Mbps on both ports. The R141 line card is support in all Metrobility chassis options. When configured with a management card (R502-M), it may be locally managed through a web browser or with NetBeacon® ESP Element Manager.

Metrobility's 10/100 AutoTwister® provides versatile connectivity for evolving network infrastructures being upgraded from existing 10Mbps copper-based networks to 100Mbps fiber networks. The AutoTwister provides media conversion and 10/100 rate adaption in a single unit, extending copper-based networks up to 100km over singlemode fiber. Now you can achieve all the features of 100Mbps fiber, such as distance and security, while minimizing costs in a mixed media environment.

Speed Flexibility
As a rate adapter, the card auto-negotiates from 10Mbps to 100Mbps, allowing existing 10Mbps devices to communicate over a 100Mbps backbone. This allows network administrators to retain existing 10Mbps devices while upgrading segments of the network as needed. As a media converter, the card also supports mixed media networks by enabling copper-to-fiber as well as fiber-to-fiber media conversion.

Remote Troubleshooting
All models incorporate Link Loss Return (LLR) and selected models also offer Metrobility's Auto-Recovery and Link Loss Carry Forward (LLCF) features to enable troubleshooting remote locations. LLR stops sending link pulses from the transmit port when link pulses are not being received. Auto-Recovery, used in conjunction with LLR, enables the card to restart the fiber link after a link loss event without a costly troubleshooting trip.

Additional features include shared network segment isolation, and auto-negotiation of full and half duplex configurations. Bi-directional Wavelength Division Multiplexing (BWDM) is also available to utilize a single strand of fiber to send and receive a two different wavelengths, doubling the capacity of the fiber (refer to Metrobility BWDM datasheet).

The AutoTwister is available for Radiance chassis platforms and as a standalone unit to provide seamless connectivity with all major switch and router manufacturers. It offers a cost-effective solution for fiber connectivity in copper switches to lower the cost per port without sacrificing function.

Patented* redundant interface provides redundant data paths for the Metrobility® Line Protection and Restoration (LPR) devices from Telco Systems. An essential connectivity tool for high priority and mission-critical applications, LPR provides fully redundant data
paths, as well as power supply redundancy, for Ethernet devices. If the primary connection fails due to a cable or hardware failure, the LPR interface switches the device’s traffic to the secondary connections within 200 microseconds.

Ensuring High Availability

LPR technology ensures a quick recovery from a physical layer failure. converges quickly to minimize packet loss. The low packet frame loss is a maximum loss of 1-2 packets (measured with minimum packet size and minimum inter-packet gap) during a failover transmission.

This physical layer solution is able to isolate failures with a faster recovery time and is simpler to implement when compared to using Spanning Tree protocol

The LPR devices have two operational modes to preserve network availability: Dynamic Recovery Mode or Network Select Mode.

Automatic traffic re-routing
When configured in Dynamic Recovery Mode, link failure is automatically detected and traffic is immediately rerouted to a secondary path or switch. This instantaneous path restoration is ideal for critical areas that require a high degree of fault tolerance.

Optional manual traffic re-routing

Network Select Mode enables the administrator to manually redirect traffic to a secondary data path, in order to perform maintenance on the first path, for example.
Both options ensure that network downtime does not affect users. Innovative Traffic Monitoring for Re-Routing SONAR (Switch on No Activity Received), available on select models, offers an even higher level of protection. By sensing not only link but also the loss of data traffic, the Metrobility SONAR-enabled LPR devices ensure reliability in the event of an upstream switch failure.

Exceptional SNMP Management
Network administrators can also maximize network uptime through proactive management. NetBeacon® ESP element management system provides end-to-end visibility of all Metrobility chassis-based network components and the ability to initiate active control through sophisticated SNMPbased management tools.

Connectivity Options
These LPR solutions support 100Mbps and 1000Mbps networks. Extended distances up to 100km may be achieved through 1550nm singlemode fiber connections.

User-configurable Gigabit Ethernet Optics
The Gigabit Ethernet LPR line card utilizes pluggable optics which may be easily replaced as network requirements change. Choose from small form factor (SFP) multimode or singlemode options.
