Description


The iConverter GM4 PoE Network Interface Devices (NID) deliver advanced Carrier Ethernet 2.0 services and provide integrated Power over Ethernet (PoE) at the demarcation. GM4 PoE NIDs function as PoE Power Sourcing Equipment in small cell (metro cell) and Wi-Fi applications, where the radio equipment can be powered through the Ethernet UTP cables.

By integrating Carrier Ethernet demarcation and PoE functions into a single device, Service Providers can easily deploy Wi-Fi hot spots and small cells almost anywhere, reduce equipment costs and overall power consumption. This integrated PoE NID speeds time to market and reduces technical risks.

The GM4 PoE NIDs are available in two PoE power levels. GM4-PoE+ and GM4-HPoE models support IEEE 802.3af PoE (15W) and 802.3at PoE+ (30W) on each RJ-45 port. The GM4-HPoE models also provide 60 Watts of High-Power PoE (also called 4 Pair PoE, PoE++, or UPoE) to all RJ-45 ports.

The GM4 PoE NID 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).

The GM4 PoE NID supports ITU-T Y.1564 and RFC 2544 service testing to easily verify the configuration and performance of Ethernet services prior to customer hand off. RFC 2544 provides per flow testing of Key Performance Indicators (KPI), such as throughput, latency, jitter and frame loss up to full wire speed. Y.1564 is a comprehensive Carrier Ethernet testing standard that tests all data flows and service attributes, including multi-flow Information Rate and Traffic Policing. Y.1564 tests all performance attributes simultaneously so testing is run quickly and efficiently, and can detect potential interaction between data flows.

The GM4 supports ITU-T G.8031 Ethernet Linear Protection Switching and G.8032v2 Ethernet Ring Protection Switching with Connectivity Check Messages (CCM) at 3.3ms rate for sub-50ms protection switching. G.8032v2 includes multi-ring protection and sub-ring support.

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 integrated management eliminates the cost and space required for external management hardware. The integrated management provides comprehensive remote configuration and performance monitoring.

The GM4 supports IPv4 and IPv6 addressing, IP-Less protocol using the IEEE 802.3ah OAM channel, SNMPv1/ v2c/v3, SSH, Telnet and serial console port.

The IP address is user-defined or can be resolved through DHCP. Telnet and serial console management interfaces are supported, and utilize an easy-to-use, menu-driven interface. The serial interface provides local configuration access.

SNMP management is available via Omnitron’s NetOutlook® SNMP Network Management Software with an intuitive Graphical User Interface, or third party SNMP software.

The GM4 Small Form Pluggable (SFP) standalone models support a wide variety of Gigabit and Fast Ethernet SFP transceivers in standard, CWDM and DWDM wavelengths.

The RJ-45 port supports 10/100/1000 and Half/Full-Duplex auto-negotiation and Pause control, with both hardware and software manual override controls. The module supports frame sizes up to 10,240 bytes.

The GM4-PoE+ and GM4-HPoE are available in 2, 4 and 5 port models, with up to four RJ-45 ports with PoE. They are DC powered, or available with an external AC to DC power adapter. Built-in mounting brackets provide table-top and wall-mounting capability, and can also be rack-mounted using the 19” 1U rack-mounting shelf or DIN-rail mounted using the optional DIN-rail Mounting Clips (8251-0).





Examples


Metro Ethernet Ring

In the application example, a Service Provider offers metro/small cell coverage in addition to Wi-Fi hot spot services. The multiport GM4 PoE NIDs provide full PoE power on each RJ-45 port.

GM4 PoE NIDs are available with two SFP fiber ports, and support G.8032 Ethernet Ring Protection Switching to enable resilient ring configurations. An on-board sensing circuit monitors the equipment enclosures for unauthorized tampering.

A GM4 PoE NID and the power supply can be installed in a compact NEMA enclosure for outdoor deployments.
