ETX-102
Basic Ethernet Demarcation Device

Smart demarcation
point between theservice provider andcustomer networks

 SLA monitoring to assure delivery of contracted Ethernet services
 VLAN bridging and stacking with P-bit, DSCP, Per Port, or ToS trafficprioritization
 Complete Ethernet OAM and Layer-2 loopback functionality for reduced Opex
 Network link protection based on 802.3ad or dual homing for increased service
resiliency
 Up to two Fast Ethernet network ports and up to four Fast Ethernet user ports

ETX-102 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-102 focuseson the service and allows the service
provider to achieve end-to-end rather
than edge-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-102 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-102 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-102 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-102
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, nonintrusive loopback, and performance
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-102 to beconnected 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 user orthe network ports. Remotemanagement via Telnet or Webbrowser.
Management traffic can be separated
from user data by creating a dedicatedmanagement VLAN.
Up to ten different stations can manage
ETX-102 simultaneously, enabling
monitoring the network status fromdifferent locations.
The following security protocols areprovided by ETX-102 to ensureclient-server communication privacy andcorrect user authentication:

The device is certified by Metro Ethernet
Forum for EPL services (MEF-9, MEF-14).

PORT COMBINATIONSETX-102 offers flexible network and user
port combinations:

RADIUS (client authentication only)

ENVIRONMENT

Ports 1 and 2 – Any standard Fast
Ethernet SFP or built-in 10/100BaseT

SSH for Secure Shell Telnet session

ETX-102/H is a temperature-hardened
version with matching SFPs intended forindustrial installations.
TYPICAL APPLICATIONSETX-102 provides access to packet
switched networks (Ethernet, IP/MPLS), as
well as next-generation SDH/SONET
backbones over Ethernet, using standard
fiber optic interface. 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 network topology.

Ports 3–6 – Built-in 10/100BaseT.
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-102 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.

SSL for Web-based management

SNMPv3 for secure SNMP sessions.
REMOTE MONITORING
ETX-102 uses the Syslog protocol togenerate and forward event notifications
over IP networks.
The device supports DDM (Digital DataManagement) SFPs according to SFF-8472
Version 9.3.
