ETX-102 Fast Ethernet Network Termination Unit

ETX-102 is a network termination unit (NTU) owned and operated by the service provider and installed at the customer premises. The RAD ETX-102 serves as clear demarcation between the user and operator networks.RAD ETX-102 Fast Ethernet Network Termination Unit, ETX-102/NULL/NULL/1UTP,ETX-102/NULL/NULL/4UTP, ETX-102/SFP-2/NULL/4UTP, ETX-102/UTP/UTP/4UTP

Providing monitoring and diagnostic as well as QoS capabilities, the RAD ETX-102 focuses on the service and allows the service provider to achieve end-to-end rather than edge-to-edge service control.

IP address, IP mask and default gateway can be automatically obtained using DHCP.

ETX-102 ETHERNET CAPABILITIES

ETX-102 features an internal bridge, operating in the VLAN-aware and VLAN-unaware modes.

VLAN stacking can be used for traffic separation between different users or services, by defining a Service VLAN ID per customer or service. When VLAN stacking is used, a Service VLAN tag is added to the user traffic and removed from network traffic. Both Service VLAN ID and Service VLAN priority can be defined.

The RAD ETX-102  provides a user-configurable fault propagation mechanism. When a link failure is detected at the network port, ETX-102 optionally shuts down any of the user ports until the network link is restored.

QoS
Different levels of service require different QoS types to be provided end-to-end. QoS can be defined per subscriber as well as per service. QoS has two aspects: rate limitation and traffic prioritization.
Hierarchical rate limitation allows defining peak traffic rate per user, per service or per traffic aggregate. This allows the user to maximize bandwidth utilization.

In order to perform user traffic prioritization, ETX-102 supports up to four separate queues, which handle traffic with different service demands, such as real-time traffic, premium data or best-effort data. In case of congestion, the relevant service already receiving higher priority at the customer premises. Traffic can be classified dynamically and mapped to different priority queues according to VLAN  priority, DSCP, or ToS. Appropriate QoS can be achieved without customer marking, by mapping different services and different user ports (port-based priority).

ETX-102 MANAGEMENT CAPABILITIES

The RAD ETX-102 can be managed using different ports and applications:
Local management via an ASCII terminal connected to the RS-232 port
Remote inband management via user or network ports. Remote management is performed using Telnet, Web browser or RADview Lite, RADís SNMP-based management system.

Management traffic can be separated from user data by creating a dedicated management VLAN.

Up to three different stations can manage ETX-102 simultaneously, enabling monitoring the network status from different locations.

RAD ETX-102 MEF 9 COMPLIANCE

ETX-102 is certified by Metro Ethernet Forum for EPL services (MEF 9).

TYPICAL APPLICATIONS FOR THE ETX-102 Fast Ethernet Network Termination Unit

Providing access to packet-switched networks (Ethernet, IP/MPLS), as well as next-generation 
SDH/SONET backbones over Ethernet, using standard fiber optic interface. Access to legacy 
networks is possible when the edge devices include tributary Ethernet ports (see Figure 1).

ETX-102 can be used for site-to-site connectivity (E-line), and for multiple site connectivity (E-LAN),  depending on network topology.
