Introduction
1.1 Overview
LA-210 is an enhanced Ethernet Access Device, MEF 9 and MEF 14 certified for
EPL (Ethernet Private Line) and EVPL (Ethernet Virtual Private Line) services.
Operating in both Bridge and Flow based working modes, incoming customer
traffic is classified and mapped according to port-based (all-in-one) bundling or
by user port and CE VLAN-ID, VLAN priority, DSCP and IP precedence. This offers
operators the flexibility to differentiate services using different kinds of
classification methods, police this traffic and enforce SLA per service.
Operating at rates of up to 22 Mbps using G.SHDSL.bis EFM bonding technology
enables transmitting data rates of up to 5.7 Mbps over each copper pair with EFM
bonding (2-wire line).
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, LA-210 operates the SHDSL link in ATM mode to be
compatible with the existing DSLAM infrastructure.
End-to-end OAM, based on IEEE 802.1ag and ITU-T Y.1731 enables Ethernet
service providers to monitor their services proactively, measure end-to-end
performance and guarantee that the customers receive the contracted SLA. Fault
monitoring and performance measurement include Frame Delay, Frame Delay
Variation, Frame Loss and Availability. LA-210 support also Single segment (link)
OAM according to IEEE 802.3ah fault indication, including remote loopback.
