RAD Data Communications 2011 Catalog

•

Mid-band Ethernet access up to

22 Mbps using EFM bonding or up

to 100 Mbps downstream/50 Mbps

upstream

•

Up to four SHDSL.bis EFM uplink pairs

or a single VDSL2 network interface

•

Up to four Fast Ethernet user ports

•

MEF-9 and MEF-14 EPL and EVPL

certified

•

Advanced QoS mechanism per

EVC/EVC.CoS

•

Ethernet link and service OAM with

performance monitoring for end-to-end

SLA control

•

Multi-standard pseudowire support for

legacy services over PSN

the network. In addition, the LA-210 features

unique P-bit re-marking capabilities, which assign

color-specific P-bit values to Ethernet frames at

the network ingress to ensure metering continuity

across the Metro Ethernet network. User traffic

that was marked “yellow” according to the CIR/EIR

parameters by the device’s QoS engine is assigned

a new P-bit value to signal its status and priority,

so that it is dropped first by 802.1Q and 802.1ad

network elements in the event of congestion. This

is especially useful in color-blind as well as in

color-aware networks with no “discard eligible”

(“yellow”) marking.

SNMP management and security

The LA-210 features flexible management

capabilities, including local management via an

ASCII terminal (RS-232). In addition, remote

management can be performed either inband or

out-of-band, using the network or user ports,

while maintaining separation between

management and user traffic via the use of

VLANs. Advanced FCAPS (Fault, Configuration,

Administration, Performance, Security) and

diagnostic tools are provided by RADview-EMS,

RAD’s carrier-class element management system,

via an SNMP-based GUI.

The LA-210 also supports a variety of access

protocols, including CLI over Telnet, SNMP, Web

server, and TFTP. Incorporated security features

include Secure Shell (SSH), Web-based Secure

Socket Layer (SSL), SNMPv3, and RADIUS, as well

as management access control list (ACL).

ETHERNET OVER DSL

LA-210

EFM DSL Network

Termination Unit

The LA-210 EFM (Ethernet in the First Mile)

access device transports Ethernet traffic over

low cost xDSL infrastructure, delivering Ethernet

services, such as inter-office LAN connectivity,

Internet access and virtual private networks

(VPNs).

The LA-210 network termination unit (NTU) is

customer-located equipment (CLE), owned and

operated by the service provider and installed at

the customer premises to mark a clear

demarcation between the user and operator

networks. It supports either multiple SHDSL.bis

(ITU 991.2) access links with EFM bonding, or a

single VDSL2 (ITU 993.2) connection with a

wide range of profiles for different deployment

architectures. This enables service providers to

deliver mid-band Ethernet and high speed

Ethernet where fiber is not present.

Service differentiation

The LA-210 features an advanced forwarding

model to facilitate management of differentiated

services. It includes the following attributes:

•

User traffic classification according to ingress

port number, VLAN ID, VLAN priority, IP

Precedence, or DSCP, as well as combinations

•

Class of service (CoS) mapping

•

Two-rate, three-color traffic policing

mechanism per CIR/CBS, EIR/EBS bandwidth

profiles

•

Hierarchical QoS with configurable Strict

Priority and WFQ (weighted fair queuing)

scheduling

•

Traffic marking and EVC shaping

These capabilities enable service differentiation

and SLA guarantees.

Ethernet OAM

Ethernet OAM is a cornerstone in the

transformation of Ethernet into a carrier-class

technology. The LA-210 EFM DSL NTU provides

two types of Ethernet OAM:

Ethernet Link OAM based on 802.3-2005

(formerly 802.3ah) allows for remote

management, including remote loopback,

remote fault indication, dying gasp, and retrieval

of MIB parameters.

Ethernet Service OAM based on 802.1ag and

Y.1731 provides end-to-end fault monitoring

and performance measurements. Ethernet OAM

enables Ethernet service providers to proactively

monitor their service end-to-end, thus

minimizing their operational expenses.

VLAN stacking and color-sensitive P-bit

re-marking

By supporting VLAN stacking (Q-in-Q), the

LA-210 enables service providers to ensure

transparent delivery of user traffic, while

minimizing the number of required VLAN IDs in
