 Compact design with 8.5-inch enclosure

ETX-26 is a compact Ethernet accessswitch with three Gigabit Ethernet and six
Fast Ethernet ports. Featuring
non-blocking architecture, small form
factor, and low power consumption, thedevice enables wire-speed datatransmission for Layer-2 Ethernet
connectivity. It is ideal for providing
Ethernet Private Line connectivity and
LAN-to-LAN interworking to small andmedium enterprises.

The device features an internal bridge thatcan operate in VLAN-aware orVLAN-unaware mode. VLAN stacking canbe used for traffic separation between
different users or services, by defining aservice VLAN ID per customer or service.
When VLAN stacking is used, a service
VLAN tag is added to user traffic andremoved from network traffic. Both VLAN
ID and VLAN priority can be defined forservices.

Supporting Ethernet Ring Protection
Switching (ERPS) per ITU-T G.8032, ETX-26
enables link resiliency to ensure highsurvivability and service continuity in theevent of link failures.

PORT COMBINATIONSETX-26 offers flexible Ethernet port
combinations:Six 10/100BaseT Fast Ethernt

One or three Gigabit Ethernet ports
with electrical or optical interfaces.

QoS
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-26 supports four priority queues per
Ethernet port with configurable scheduling( strict priority or WFQ). In addition thedevice supports ingress and egress rate
limiting to control the incoming andoutgoing traffic bandwidth.

To prioritize user traffic, ETX-26 features
up to four separate queues that handle
traffic with different service demands,
such as real-time traffic, premium data, orbest-effort data. In case of 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).
NETWORK INTERFACE REDUNDANCYTo ensure high survivability and service
continuity, ETX-26 features Ethernet ringprotection switching per ITU-T G.8032v1,allowing the device to be connected to an
Ethernet ring topology and achieve
50 msec protection restore time in case oflink failure.

PROPRIETARY POWER OVER ETHERNET(PoE)
Power over Ethernet is provided on Fast
Ethernet ports 5 and 6 if the unit has a
48V DC power supply.
The ETX-26 device with proprietary Powerover Ethernet capability can be used tofeed the outdoor unit (ODU) of RAD’s
Airmux-200/400 broadband wirelesstransmission devices, providing a single
indoor device for Ethernet connectivity
and ODU power feeding.
DYING GASPETX-26 reports power failure (if the unit isconnected to AC power), thus enabling
the device to properly disconnect from thenetwork with notification of the reason
for the service problem.
MANAGEMENTThe unit can be managed using thefollowing ports and applications:Local management via an ASCII
Terminal connected to the RS-232 port

Inband management via any Ethernet
portRemote management via Telnet, Web
browser, or an SNMP-basedmanagement system.
