ETHERNET OVER FIBER

The ETX-220A Carrier Ethernet demarcation device

delivers SLA-based business services to the

customer premises over native Ethernet access.

Transporting up to 10 Gbps of user throughput,

it converges voice and data services over a

unified Ethernet, IP or MPLS network.

The ETX-220A features two 10-Gigabit Ethernet

network ports and a 10-GbE user port

(hardware-ready for 1+1 redundancy). All ports

are SFP+ or XFP compatible.

Hardware-ready for RAD’s SyncToP platform of

synchronization and timing over packet feature

set, the ETX-220A is designed to support

standard technologies, such as 1588v2 Precision

Time Protocol and Synchronous Ethernet. For

further details on the ETX-220A’s SyncToP

capabilities, please refer to page 76.

Hardware-based Ethernet OAM and

performance monitoring for SLA assurance

The ETX-220A combines Ethernet demarcation

with test-head functionalities, featuring a

complete Ethernet OAM suite that includes

Ethernet Link OAM (IEEE standard 802.3-2005,

formerly 802.3ah), Ethernet Service OAM (IEEE

802.1ag) and Performance Monitoring (ITU-T

Y.1731). These are enhanced with a built-in

RFC-2544 test generation engine, as well as

Layer 1, 2 and 3 diagnostic loopback capabilities

with MAC and IP address swap.

Featuring ultra-fast, hardware-based processing

capabilities, the ETX-220A performs OAM and

PM measurements in under 1 microsecond with

maximum precision.

The ETX-220A offers advanced SLA assurance

tools, including user-defined KPI (key

performance indicators) threshold configuration,

real-time SLA violation alerts and per-flow daily

statistics reporting.

Remote provisioning and traffic

management

The ETX-220A features advanced softcore

architecture for efficient handling of multi-

priority traffic on a per-flow basis, with ultra-

high capacity that enables simultaneous

processing of hundreds of service flows. The

device enables multi-criteria traffic classification

as well as metering, policing and shaping to

help carriers rate-limit user traffic according to

pre-defined CIR (committed information rate)

and EIR (excess information rate) profiles.

Enhanced quality of service is further supported

by a hierarchical scheduling mechanism that

combines Strict Priority (SP) and weighted fair

queue (WFQ) scheduling, as well as weighted

random early detection (WRED) policy and color-

sensitive P-bit re-marking packet editing.

Uplink resiliency and protection

The ETX-220A supports dual homing link

redundancy and Link Aggregation (LAG) using

802.3ad LACP. In addition, path protection is

supported with Ethernet Linear Protection

Switching per ITU-T G.8031.

Management and security

The ETX-220A features flexible management

capabilities, including local management via an

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

management can be performed either inband

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

using a dedicated management port, 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-220A also supports a variety of access

protocols, including CLI over Telnet, SNMP, and

TFTP. Incorporated security features include Secure

Shell (SSH), Web-based Secure Socket Layer (SSL),

SNMPv3, RADIUS and Terminal Access Controller

Access-Control System (TACACS+), as well as

management access control list (ACL).
