The iConverter GM3 is a flexible and cost-effective Network Interface Device (NID) with Service and Link Operations, Administration and Maintenance (OAM) capabilities. The GM3 provides Carrier Ethernet service demarcation with rapid service activation, SLA assurance and fault management.

The GM3 supports MEF-certified User-to-Network Interface (UNI) functions including Class of Service (CoS) management, granular rate-limiting, and 802.1ad Provider Bridge VLAN stacking (Q-in-Q) for service multiplexing of multiple E-Line, E-LAN and E-Tree services. The GM3 provides per-flow service mapping, traffic policing and shaping. CIR/EIR “two rates, three colors” ingress port policing provides granular bandwidth optimization. The GM3 also provides advanced classification and filtering of subscriber traffic as an EVC or CoS flow based on layer 1, 2, 3 or 4 identifiers.

The GM3 supports carrier-class Ethernet Service OAM standards. IEEE 802.1ag Connectivity Fault Management (CFM) proactively monitors service availability and provides tools for rapid fault isolation. ITU-T Y.1731 Performance Monitoring provides the ability to monitor key SLA parameters including frame delay, frame delay variation and frame loss. These OAM features provide proactive fault detection and rapid isolation of potential service problems, enabling SLA assurance while reducing Operational costs (OPEX).

iConverter GM3 NIDs provide industry-leading interoperability with the most comprehensive 802.1ag and Y.1731 standards implementations.

Zero-Touch Provisioning (ZTP) allows providers to achieve efficiencies in service activation that accelerate turn up and reduce the need for onsite technicians. ZTP allows service provisioning to be centralized, standardized and remotely managed.

The GM3 fiber ports support Gigabit (1000BASE-X) or Fast Ethernet (100BASE-FX) SFP transceivers, and the copper interface operates at 1000, 100 or 10Mbps. The GM3 is available in 2-port or 3-port options. The 3-port configuration supports geo-diverse redundant access links or multi-tenant demarcation with two subscriber ports.

The GM3 is available as a compact standalone unit or as a chassis plug-in module. The GM3 plug-in module can be mounted in any iConverter chassis and manage other modules in the same chassis, and operate as a Network Interface Device. It features two Gigabit Ethernet backplane ports for connectivity to adjacent modules in a chassis for multi-port and multi-service configurations.

The standalone GM3 is available with or without integrated mounting brackets. It is DC powered and available with an external AC/DC power adapter, or with a terminal connector for wiring directly to a DC power source.

The GM3 also functions as a fiber transport module for the modular iConverter T1/E1 and Ethernet Multiplexer System.

The GM3 provides comprehensive support of the latest carrier class Ethernet Service OAM standards, enabling service assurance and reducing operational costs. IEEE 802.1ag Connectivity Fault Management (CFM) provides Maintenance Domain and Maintenance Associations for Subscribers, and multiple Service Providers. IEEE 802.1ag functions proactively monitor service availability and provide tools for rapid fault isolation.

ITU-T Y.1731 Performance Monitoring provides the ability to monitor SLA parameters including frame delay, frame delay variation and frame loss. Hardware-based Delay Measurement and Loopback Measurement with nanosecond resolution provides the highest level of service testing and SLA assurance for delay sensitive voice and financial services.

802.3ah Link OAM provides tools for fault management and troubleshooting the first mile access links.

In this application, the GM3 NIDs on the top are used for demarcation of LTE Mobile Backhaul and provide performance monitoring for latency sensitive voice data.

The GM3 NIDs on the bottom are providing demarcation for business services. The GM3 NID at the subscriber location on the right is providing a UNI with multiplexed services to two other locations.
