Omnitron iConverter GX/TM2

Protel - iconverter gxtm2The iConverter GX/TM2 is a carrier-grade Network Interface Device (NID) that provides 10/100/1000 copper to Gigabit Ethernet fibre media conversion with integrated management.

For Service Providers, the GX/TM2 NID provides MEF 9, 14 and 21 certified demarcation of Carrier Ethernet E-Line services. The GX/TM2 is a cost-effective demarcation device for Service Providers to deliver best-effort Ethernet services.

For Enterprise and Government and Utility networks, the GX/TM2 enables secure demarcation and management for mission-critical applications delivered over fibre infrastructure.

IEEE 802.3ah Operations, Administration and Maintenance
The GX/TM2 supports the IEEE 802.3ah Link OAM standard with Fault Detection, Performance Monitoring and Remote Loopback for Ethernet in the First Mile (EFM) access links.

Fault Detection
The GX/TM2 detects and indicates link faults, dying gasp and other critical events. The GX/TM2 also supports Unidirectional Link Fault Detection that indicates faults in either direction of the fibre link.

Performance Monitoring
802.3ah Performance Monitoring tools are used for the detection and notification of link performance (quality) faults. Ethernet data performance can deteriorate slowly over time, and the GX/TM2 allows the setting of error-per-second thresholds with event notification for early indication of issues that may be resolved prior to loss of service.

Remote Loopback
Remote Loopback is used for fault localization and link performance testing. When a GX/TM2 port is in loopback mode, all received link traffic is looped back and transmitted back unaltered. The statistics from the GX/TM2 port and the remote link partner can be compared for consistency.

VLAN with 802.1ad Q-in-Q and QoS for E-Line services
The iConverter GX/TM2 supports the IEEE 802.1Q tag Virtual Local Area Network (VLAN) packet tagging and untagging (including Q-in-Q tunneling and 802.1ad service provider tag) and the 802.1p Quality of Service priority standards.

VLAN 802.1ad tunneling technology enables service providers to offer their customers E-Line services via Ethernet Virtual Circuits (EVC). The 802.1p Quality of Service (QoS) prioritization standard enables delivery of high-priority, real-time applications such as voice and video over Ethernet.

Port Bandwidth Control and Port Access Control
The enhanced Bandwidth Control feature controls bandwidth between the fibre and RJ-45 ports in 64Kbps increments from 64K to Full Line Speed.

The GX/TM2 features Port Access Control which blocks user service while maintaining the network link. Port Access Control enables the service provider to control user access while maintaining port configuration for easy disabling or enabling of customer service. Port Access Control provides enterprise administrators the capability to improve network security by controlling port access when the port is not in use.

Port Statistics and Optical Performance Statistics
The GX/TM2 supports reporting of utilization, port and optical performance statistics. Port statistics are available for 38 different parameters for the RJ-45 and fibre ports. Additionally, full optical performance statistics are available on SFP fibre transceivers with a digital diagnostic interface. Port and optical performance statistics reporting provides the ability to monitor customer bandwidth utilization, network performance and the link signal quality for each individual port.

Fibre Port Options
GX/TM2 models with ST, SC and LC fixed-fibre connectors are available with multimode (MM) dual fibre, single-mode (SM) dual fibre and single-mode single-fibre (SF) options. The GX/TM2 Small Form Pluggable (SFP) model supports a wide variety of 1000BASE-X SFP transceivers in standard and CWDM wavelengths.

Link Modes
The GX/TM2 features multiple, user-selectable link fault detection modes, including Link Fault Propagation, Remote Fault Detection and Asymmetrical Fault Detection. These Link Modes provide rapid fault detection and isolation by monitoring the state of the cabling hardware, and operate independently of the network management.

Form Factors
The GX/TM2 is available as a compact standalone unit or as a chassis plug-in module. The hot-swappable GX/TM2 plug-in module can be mounted in a 19 or 5-Module chassis with any combination of redundant AC and DC power supplies. It can also be mounted in a 2-Module AC or DC powered chassis, or in a 1-Module chassis with AC or DC power input.

The plug-in module can manage other modules in the same chassis and operate as a managed 10/100/1000 media converter. It features two Ethernet backplane ports for connectivity to adjacent modules in a chassis for multi-port and multi-service configurations.

The standalone GX/TM2 is available as a table top or wall-mount unit. The table top model can be DIN-rail mounted using an optional DIN-rail mounting kit. Both the table top and the wall-mount models are DC powered and are available with an external AC to DC power adapter or a terminal connector for DC power. The GX/TM2 standalone unit combines management capability with a compact chassis for deployment at the demarcation point.

The GX/TM2 has integrated management, eliminating the cost and space required for external management hardware. The iConverter management system provides comprehensive remote configuration and performance monitoring.

iConverter management is available via IP-Less protocol using the 802.3ah OAM channel or Omnitron’s Secure OAM channel, or using SNMP or Telnet.

Management is accessed via Omnitron’s NetOutlook® SNMP Network Management Software with an intuitive Graphical User Interface, or third party SNMP software. Telnet and CLI management interfaces are also supported, and utilize an easy-to-use, menu-driven interface. The CLI interface is accessed via a Serial Console Port, that provides local configuration and allows for firmware updates. Additionally, the port can be connected to a serial modem to provide an alternative remote management path.

IP-Based Secure Management
The GX/TM2 can be managed through IP protocols, SNMPv1, SNMPv2c, SNMPv3 and Telnet. The IP address of the GX/TM2 can be user-defined or resolved through the DHCP host on the network. The IP protocols for management access can be enabled or disabled individually or as a group. Access to the management is protected by password authentication. SMNPv3 strengthens secure access to devices by a combination of authenticating and encrypting packets over the network. Management VLAN can also be defined to separate management traffic from customer traffic.

802.3ah and Secure OAM Management Channels
When utilizing a Remote OAM management channel (Secure IP-less or 802.3ah), the remote demarcation NID is securely managed by its fiber link partner located at the Central Office or Point of Presence. The network management IP address is accessed from the Network Management Module (NMM2) in the 19-Module Chassis providing a secure management channel to all remote demarcation NIDs

Application Example

Secure IP-less Management

An iConverter GX/TM2 is installed in a 19-Module Chassis with an iConverter Network Management Module (NMM2) at the Central Office or Network Core. The GX/TM2 has an integrated management processor that isolates the encrypted management data from the customer data and communicates with the NMM2 via a separate management backplane bus. Management traffic on the user data lines is IP-less and carried on a securely encrypted data channel to protect the management from unauthorized access. The 19-Module chassis requires only a single IP address to manage itself and up to eighteen remote GX/TM2 NIDs managed by the OAM channel. This is the ideal configuration for networks that separate secure management traffic from the service (customer) traffic on different networks, or when management IP addresses are at a premium.


GX/TM2 Application Example 1

Securely Managed Access Network

At the Central Office, the GX/TM2 plug-in module is installed in a managed iConverter 19-Module chassis for high-density fibre distribution from UTP switch equipment. At Customer Premises on the right, a GX/TM2 plug-in module and an iConverter 4GT four-port switch module are installed in a 2-Module chassis, and share data via the Ethernet Backplane. This configuration functions as a remotely managed demarcation switch with a fibre uplink port and five copper ports that drop off Ethernet services. At Customer Premises on the left, the GX/TM2 standalone NID provides a fibre uplink to a single copper port for intelligent demarcation of Ethernet services.

This configuration can also be deployed in an Enterprise campus, municipal, government or utility network.
