The Ethernet over VDSL (Very high bit rate Digital Subscriber Line) or EoV technology enables the creation of high-speed links of up to 15 Mbps full duplex, over standard telephone lines. The Ethernet over VDSL product line is delivering standard Ethernet traffic over VDSL transport, which reaches distances of up to 1500 m, in parallel to the POTS or ISDN service.

It integrated with the different OptiSwitch™ family modules including full support for QoS, rate limitation per flow, bandwidth management, marking and intrusion control over the EoV traffic.

The Ethernet carrier uses standard Ethernet frames, and supports the full range of MRV Ethernet features supported in the OptiSwitch™ such as Ethernet switching, Rapid Spanning Tree Protocol (RSTP), VLAN Encapsulation (VMAN) and Virtual LAN (VLAN).

Building Blocks

The EoV solution comprises three elements in addition to the OptiSwitch chassis and modules:

• EoV OptiSwitch modules : available in configurations of 8 EoV ports, hybrid models of 4 EoV ports and two ports of 100Base-FX or two ports of 10/100Base-TX and a repeater module which mixes 4 ports of NT (Network Termination) side and 4 ports of LT (Line Termination) side.
The different modules available in two basic shapes: Fully support for Classification and QoS or Layer2 based EoV modules.

• Extensive QoS EoV : The OptiSwitch EM2004-8EoV module series features MRV unique Ethernet Circuit Switching technology. This module provides EoV Layer 2-3-4 switching capabilities with QoS techniques. The on-board switching engines are capable of recognizing a series of frames as belonging to a specific flow (“Ethernet Circuit”), and apply policy based traffic classification and prioritization based on:
• DiffServ - ToS
• 802.1p queue mapping
• Per VLAN membership
• Per ingress PORT
• Layer 2-3-4 traffic flows:
MAC, IP, TCP/UDP source and/or destination
• Per protocol


High-flexibility bandwidth management with EM2004 QoS modules allows VDSL rate limiting from 64 Kbps up to 15 Mbps on each flow (“Ethernet Circuit”) with 1 Kbps granularity. Rate limiting allows multiple bandwidth provisioning policies to be applied and to provide maximum flexibility for network designers to build intelligent network.

• EoV Customer premises equipment (CPE) : an Ethernet over VDSL modem, with a single RJ-45 port for 10/100Base-TX, and two RJ- 11ports– one connected to the voice line that carries the voice and Ethernet over VDSL traffic to the out-going line

• EoV Splitter : a passive device which functions as a low pass filter, which separates the high- frequencies used by the VDSL carrier, from the Voice traffic. The splitter is available in a configuration of 30 ports

Features
Modular Ethernet VDSL with QoS solution : The most advanced in the industry modular Ethernet over VDSL (EoV) technology enables the creation of high-speed links of up to 15 Mbps full duplex, over standard telephone lines.
NT and LT side : Module and CPE are available as NT (Network Termination) and LT side (Line Termination), for modem-to-modem and module-to-module connectivity
Support ETSI Standard : The basic EoV model supports the VDSL standards – ETSI plans 997 and ETSI plan 998.
Dynamic Carrier Management (Self-healing) : Ethernet over VDSL uses standard copper telephone cables as the physical transmission medium.
Long range : A special model of the system delivers long-range VDSL transmission, which can reach distances of up to 2.4 Km with 4 Mbps, full duplex traffic.
Modularity : With over 90 different types of modules and a variety of 2, 4, 8, 12 and 24 slots chassis, OptiSwitch enables a “pay as you grow” model: only the port density required at the time of installation is acquired. Thanks to its “all-modular” design, you can either replace/add modules as needed, or reuse the existing modules in a larger chassis.
Intelligence by Classifier Engine : The OptiSwitch classification modules provide network intelligence to implement features such as access rules according to Layer 2-3-4 parameters like VLAN, IP and TCP/UDP with rate limit and marking of QoS fields in the packet header.
Bandwidth Control : A network partitioning is required to preserve each valuable Kilobit and ensure allocated flows from the end users to network resources. OptiSwitch classification modules allow isolation and rate limitation of the traffic based on variable flows definitions.
Security : The implementation of Policy ACL capability into the OptiSwitch family permits a powerful feature to enforce another protection at the access and aggregation points for the Enterprise or Metro Carrier.
Density : Telco chassis with highest optical, copper and VDSL density per rack in the industry
Resiliency and Redundancy : OptiSwitch, serving as a critical network component, supports different level of redundancy at all layers to increase system resilience and redundancy.
Management : Fully managed solution through out-of-band CLI or in-band powerful Comprehensive SNMP graphical managed solution – MegaVision Web.
Integrated Solution: The modular solution integrated EoV with Voice E1/T1 TDM over Ethernet, Gigabit Multimode Extender over fiber, Optical wireless, different fiber and copper interface all in the same chassis.
