Basic Ethernet Demarcation Device

Smart demarcation

service provider and Complete Ethernet OAM and Layer-2 loopback functionality for reduced Opex

customer networks

 Network link protection based on 802.3ad or dual homing for increased service
resiliency
 Up to two Gigabit Ethernet network ports and up to four Gigabit Ethernet userportsETX-202 is a carrier Ethernet demarcation
device owned and operated by the service
provider and installed at the customer
premises.

ETHERNET CAPABILITIESProviding monitoring and diagnostic aswell as QoS capabilities, ETX-202 focuseson the service and allows the service
provider to achieve end to end rather thanedge-to-edge service control.

VLAN stacking can be used for traffic
separation between different users orservices by defining a Service VLAN ID per
customer or service. When VLAN stacking
is used, a Service VLAN tag is added touser traffic and removed from network
traffic. Both Service VLAN ID and Service
VLAN priority can be defined.

IP address, IP mask, and default gateway
can be automatically obtained using DHCP.

ETX-202 features an internal bridge,
operating in VLAN-aware or VLAN-unawaremode.

ETHERNET OAM

FAULT PROPAGATION

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 two aspects: rate
limitation and traffic prioritization.

ETX-202 provides comprehensive Ethernet
OAM capabilities:

The unit provides a user-configurable fault
propagation mechanism. When a link
failure is detected at the network port,
ETX-202 optionally shuts down a user port
until the network link is restored.

Hierarchical rate limitation defines peaktraffic rate per user, port service, or per
traffic aggregate. This maximizes
bandwidth utilization.
For prioritizing user traffic, ETX-202
features up to four separate queues,
which handle traffic with different service
demands, such as real-time traffic,
premium data, or best-effort data. In caseof congestion, the relevant service
receives higher priority at the customer
premises.
Traffic can be classified dynamically andmapped to different priority queues
according to VLAN priority, DSCP, Per Port,or ToS. Appropriate QoS can be achieved
without customer marking, by mapping
different services and different user ports(port-based priority).

End-to-end (path) based on IEEE
802.1ag and Y.1731 for continuity
check, non-intrusive loopback, andperformance management, including
Frame Delay, Frame Delay Variation,
Frame Loss, Availability etc.
Single segment (link) OAM according toIEEE 802.3ah for remote management
and fault indication, including remoteloopback, dying gasp, and MIB
parameters retrieval
Performance monitoring includes
Frame Delay, Frame Delay Variation,
Frame Loss and Availability.

NETWORK INTERFACE REDUNDANCYThe unit supports two redundancy modes:
Link aggregation (1+1) based onIEEE 802.3ad



Dual homing (1:1), allowing ETX-202
to be connected to two different
upstream devices.

MEF-9, MEF-14 CERTIFICATIONMANAGEMENTThe unit can be managed using thefollowing ports and applications:Local management via an ASCII
terminal connected to the RS-232 port

Remote inband management via
network ports. Remote management
via Telnet or Web browser.

Management traffic can be separated
from user data by creating a dedicatedmanagement VLAN.
Up to ten different stations can manage
ETX-202 simultaneously, enabling
monitoring the network status fromdifferent locations.
The following security protocols areprovided by ETX-202 to ensureclient-server communication privacy andcorrect user authentication:

ETX-202 is certified by the Metro Ethernet
Forum for EPL services (MEF-9, MEF-14).

PORT COMBINATIONSRADIUS (client authentication only)

ETX-202 offers flexible network and user
port combinations:

SSL for Web-based management

ENVIRONMENTPorts 1 and 2 – Any Gigabit Ethernet
fiber optic SFP or built-in
10/100/1000BaseT

SSH for Secure Shell Telnet session

SNMPv3 for secure SNMP sessions.

Ports 3–6 – Any Gigabit Ethernet fiber
optic SFP or built-in
10/100/1000BaseT.

ETX-202/H is a temperature-hardened
version with matching SFPs intended forindustrial installations.
TYPICAL APPLICATIONSETX-202 provides access to packet
switched networks (Ethernet, IP/MPLS), as
well as next-generation SDH/SONET
backbones over Ethernet, using standard
fiber optic interfaces. Access to legacy
networks is possible when the edge
devices include tributary Ethernet ports.
The termination unit can be used forsite-to-site connectivity(E-line), and for multiple site connectivity(E-LAN), depending on the network
topology.

LAYER-2 LOOPBACK WITH MAC
SWAPPING
Layer-2 link integrity can be tested by anon-disruptive loopback with MAC address
swapping. When the loopback is activated,
ETX-202 exchanges source anddestination MAC addresses of theincoming packets. This loopback can be
performed per VLAN (or EVC), it passes
through Ethernet bridges and does notdisrupt traffic flows that are not being
tested.

REMOTE MONITORING
ETX-202 uses the Syslog protocol togenerate and forward event notifications
over IP networks.
ETX-202 supports DDM (Digital DataManagement) SFPs according to SFF-8472
Version 9.3.
