Basic Ethernet

Demarcation Devices

SLA assurance, Ethernet OAM and

performance monitoring

The ETX-102, ETX-201 and ETX-202 feature

enhanced Ethernet OAM capabilities, to enable

remote and automatic fault localization without

service interruptions or costly on-site

inspections. The devices’ comprehensive

Ethernet OAM suite includes Ethernet Link OAM

(IEEE standard 802.3-2005, formerly 802.3ah),

Ethernet Service OAM (IEEE 802.1ag) and

Performance Measurement (ITU-T Y.1731).

In addition to the non-intrusive OAM-based

loopback testing, the ETX demarcation devices

support Layer 1 and Layer 2 loopbacks for link

integrity diagnostics, performed per port,

whereby the source and destination MAC

addresses are swapped without disrupting the

traffic flows that are not being tested.

Remote provisioning and traffic

management

The ETX devices are equipped with advanced,

software-based capabilities for handling multi-

priority traffic, ensuring latency, jitter and

packet delivery performance on a per-port

basis. The devices support traffic classification

according to user-defined criteria, including

VLAN priority (P-bit), DSCP/ToS and subscriber

port. In addition, metering and policing

functionalities help carriers to rate-limit user

traffic according to pre-defined CIR (committed

information rate) profiles, while traffic

prioritization per class of service guarantees

level of service during periods of congestion.

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

devices enable service providers to ensure

transparent delivery of user traffic, while

minimizing the number of required VLAN IDs in

the network.

Uplink redundancy

Some customers require high level service

resiliency. In such cases, the demarcation

device should also be able to provide uplink

redundancy to protect the access link and allow

five nines (99.999%) reliability. The ETX-102,

ETX-201 and ETX-202 offer both dual homing

and single homing redundancy.

Management and security

The ETX-102, ETX-201 and ETX-202 feature

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 ETX-102, ETX-201 and ETX-202 also

support a variety of access protocols, including

Telnet, SNMP, Web server, and TFTP.

Incorporated security features include Secure

Shell (SSH), Web-based Secure Socket Layer

(SSL), SNMPv3, and RADIUS.

Available ETX configurations

All ETX units are equipped with two network

ports for link redundancy and are available with

SFP or UTP port configurations. The ETX-102 is

a Fast Ethernet NTU with two network ports

and up to four subscriber ports. The ETX-201 is

a Gigabit Ethernet NTU with two GbE network

ports (SFP only) and up to four Fast Ethernet

subscriber ports. The ETX-202 is an all Gigabit

Ethernet NTU with two GbE network ports and

up to four GbE subscriber ports.

End-to-end service and transport

demarcation

The ETX-102, ETX-201 and ETX-202 basic Ethernet

demarcation devices deliver up to 1 Gigabit of

user throughput over native Ethernet access.

They provide transport demarcation to SLA-based

Layer 3 business services, such as IP VPN, VoIP

and dedicated Internet access, converging voice

and data services over a unified Ethernet, IP or

MPLS network. Alternatively, the ETX devices

perform service demarcation for Layer 2

applications, such as LAN-to-LAN services, with

end-to-end quality of service control.
