The iConverter GM3 is a flexible and cost-effective Network Interface Device (NID) with Service Operations, Administration and Maintenance (OAM), and Link 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.
