The Access CompanyETX-205A
Carrier Ethernet Demarcation DeviceSFP/COPPER COMBO PORTS
All ETX-205A units are equipped withSFP/copper combo Ethernet ports,
enabling flexible mixture of fiber optic andcopper interfaces in one device. The SFPports accommodate a wide range of Fast
Ethernet and Gigabit Ethernet SFP
transceivers, allowing service providers toseamlessly connect customers located at
different distances from the device.
TYPICAL APPLICATIONSETX-205A is used in the following
applications:

Ethernet demarcation device –ETX-205A separates the service
provider network, the access providernetwork, and the customer network,
providing proactive service monitoringand easy fault localization throughout
the entire network (see Figure 1)
Mobile demarcation device – ETX-205A
is installed at the operator tower andcontroller sites equipped with an
Ethernet port, connecting the NodeB
or eNodeB to the packet network,
providing sophisticated traffic
management and service assurance
capabilities, including proactive service
monitoring and fault identification
throughout the entire network (seeFigure 2).

FLEXIBLE TRAFFIC MAPPINGHIERARCHICAL QUALITY OF SERVICE(H-QOS)

maximum precision, offering the followingpowerful benefits:

Different service types require different
levels of QoS to be provided end-to-end.
QoS can be defined per subscriber as wellas per service. QoS has three aspects: rate
limitation, traffic shaping, and traffic
prioritization.

Immediate detection of loss ofcontinuity (LOC), ensuring under 50 ms
protection switchingHighly accurate frame loss
measurements of live trafficFlow-level (per CoS) monitoring,enabling simultaneous processing ofmultiple OAM sessions with E-LAN andE-TREE supportNon-disruptive MAC and IP levelloopback testing of network integrity.

Traffic policing is applied per flow or groupof flows, and operates according to thedual token bucket mechanism based onuser-configurable CIR + CBS and EIR + EBS.
Traffic can be limited to the line rate or
the data rate.
Every flow per EVC or EVC.cos has its own
queues and scheduler supporting strictpriority and weighted fair queues (WFQ).
Queue blocks of eight queues per EVC arescheduled and shaped, forming an H-QoS
model with shaped services and prioritizedclasses of service. The WRED mechanism isused for smart packet drop.
The VLAN priority bit in Ethernet frames
can be modified at network ingress
according to the ‘color’ of the frame. This
allows service consistency and QoS
continuity across color-aware (dropeligible enabled) as well as color-unawarenetworks.
HARDWARE-BASED ETHERNET OAM
Featuring ultra fast, hardware-poweredprocessing, ETX-205A performs OAM andPM measurements in line rate with

ETX-205A provides these types ofEthernet OAM:Single-segment (link) OAM according
to IEEE 802.3-2005 for remotemanagement and fault indication,
including remote loopback, dying gasp
with SNMP trap, and MIB parameter
retrieval. Active and passive mode aresupported.

End-to-end connectivity OAM basedon IEEE 802.1ag-D8 that enables
Ethernet service providers to monitor
their services proactively andguarantee that customers receive thecontracted SLA

End-to-end service and performancemonitoring based on ITU-T Y.1731.
Fault monitoring and end-to-end
performance measurement include
delay, delay variation, frame loss andavailability.

Traffic is mapped to the Ethernet flows
using very flexible classification criteria
based on incoming port (port-based
all-to-one bundling), VLAN ID, VLAN
priority, IP precedence, DSCP, Ethertype,and IP/MAC source/destination address.
Classification is defined for both VLAN
tagged as well as untagged traffic.
The device can be configured to passthrough Layer-2 control frames (including
other vendors’ L2CP frames, and withoptional MAC change) across the network,to peer supported protocols(IEEE 802.3-2005 and LACP), or to discard
the L2CP frames.

FAULT PROPAGATIONFLOW LEVEL RESILIENCYMOBILE BACKHAUL SYNCHRONIZATIONThe unit provides a user-configurable fault
propagation mechanism in the
network-to-user or user-to-network
direction.

ETX-205A applies standard ITU-T G.8031
Ethernet Linear Protection switching forfast protection of one or more EVCs fromend to end. The standard implementation
ensures interoperability with third-party
devices. With standard APS functionality,
Ethernet OAM messages provide
bandwidth-efficient unidirectional orbidirectional 1:1 protection

ETX-205A implements the RAD SyncTop™
synchronization suite (see Figure 2),
allowing cellular backhaul providers tomeet the necessary synchronization
requirements without the need to invest
in dedicated timing equipment at everybase station. ETX-205A timing features
include:When a link failure is detected or OAM
failure received, ETX-205A can shut down
the affected port or forward the OAM
failure message. The fault propagation
mechanism enables routers and switches
connected to both ends of the link toreroute the traffic to the redundancy
path.
RFC-2544
The device provides a built-in RFC-2544
wire-speed traffic generator and analyzer
for unidirectional and bidirectional testingof throughput, latency, and frame loss.
Based on standard OAM messages, thetests can be simultaneously performed
over multiple flows, at the EVC.CoS level.
Enhanced RFC-2544 functionality provides
service-oriented KPI analysis. SLA
conformance is measured per service
bandwidth and packet size, within auser-defined amount of time, for faster
service introduction.
NETWORK INTERFACE RESILIENCYETX-205A provides the following network
interface protection modes:
802.3ad Link aggregation (LAG),
providing 1:1 link protection with Link
Aggregation Control Protocol (LACP)
supportDual homing (1:1), allowing ETX-205A
units to be connected to two different
upstream devices.

The EVC protection path can be configuredon the same network port, enabling thetransport network to provide analternative path for the working andprotecting paths. It can also be configured
on separate network ports, adding
protection at the access layer andenabling load balancing on network
interfaces by splitting traffic between thetwo network ports.
The performance of the hardware-based
Ethernet OAM together with protection
switching for physical layer failure ensures
fast protection in any scenario.
The flow level protection provides a fullset of manual commands for maintenancepurposes.
INTEGRATED SMART SFP
Integrated management of MiRICi smart
SFPs provides TDM (E1/T1/E3/T3/OC-3/STM-1) connectivity over PDH orSDH legacy networks. ETX-205A supports
configuration and statistic collection forthe smart SFP TDM port.

Synchronous Ethernet (SyncE) per
ITU-T G.8261-G.8264

IEEE 1588v2 Precision Time Protocol

time stamping and hardware
provisioning for PTP slave functionalityExternal clock in/out interfaces (T3/T4)
supporting 2MHz, 2M bits, and T1frequencies

Primary/secondary clock redundancy

performance.

LAYER-2/ LAYER-3 LOOPBACK WITH
MAC AND IP ADDRESS SWAPPING
Layer-2 and/or layer-3 network integrity
can be tested by a non-disruptive
loopback performed per flow, withswapping of MAC address and optionallyIP address. When the loopback isactivated, ETX-205A exchanges the sourceand destination MAC/IP addresses of theincoming packets. This loopback passes
through Ethernet bridges (MAC address)
and routers (IP address).

DYING GASPTRAP SYNCHRONIZATIONMANAGEMENT PORTS

ETX-205A reports power failures todefined network management stations bysending an IEEE 802.3-2005 message orSNMP trap, thus enabling the unit toproperly disconnect from the networkwith notification of the reason for theservice problem.

Traps are sent with sequence IDs tonetwork manager groups, to enable themanagers to detect when traps are lostand request the traps be sent again.
