MRV Products
Ethernet-over-VDSL providing
Broadband Video, Voice, and Data over Telephone Lines
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 OptiSwitchT 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 OptiSwitchT
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
