RV-EMS/NGN LA-210 Overview of LA-210 1-1
Chapter 1
Introduction
This chapter provides an overview for managing LA-210 using the RADview-
EMS/NGN LA-210 management solution. It introduces the graphical user
interface. It is assumed that you are familiar with basic RADview-EMS/NGN
operations. For more information about basic RADview-EMS/NGN operations,
refer to the
RADview-EMS/NGN (PC) or (UNIX) User's Manual .

1.1 Overview of LA-210
RV-EMS/NGN LA-210 is an advanced DSL Ethernet access device operating at
rates of up to 22 Mbps using G.SHDSL.bis EFM bonding technology (TC-PAM 16 or
TC-PAM 32 line coding technologies) to transmit data rates of up to 5.7 Mbps
over each copper pair with EFM bonding (2-wire line).
RV-EMS/NGN LA-210 supports multiple data rates and works in full duplex mode
over 2-wire, 4-wire, or 8-wire lines.
In addition to the EFM mode, RV-EMS/NGN LA-210 operates the SHDSL link in
ATM mode to be compatible with the existing DSLAM infrastructure.
EFM bonding ensures that a failure or addition of a link does not drop the traffic
being transmitted over the other wires in the group, nor is the capacity of the
group decreased when a new link is added at lower rate. This is particularly
relevant for operators offering Ethernet services in the First Mile where fiber is
absent or impractical to install.
RV-EMS/NGN LA-210 implements the IEEE.1Q standards to provide VLAN-tagging
with four levels of prioritization, enabling carriers to offer differentiated Ethernet
services. VLAN tagging can also be employed to separate traffic, ensuring
transparency of the customer traffic and bolstering security of management
traffic.
RV-EMS/NGN LA-210 provides monitoring, control, and diagnostics of local and
remote units via a terminal supervisory port.
