ETX-26 Ethernet Access Switch
ETX-26 Ethernet Access Switch key features include:
Ethernet Access switch with three Gigabit Ethernet and six Fast Ethernet ports
Link resiliency using Ethernet Ring Protection Switching per ITU-T G.8032
Quality of Service with queue mapping per port, P-Bit, DSCP, or ToS
Ethernet bridging and switching with VLAN-aware and VLAN-unaware modes, and VLAN stacking
Compact design with 8.5-inch enclosure
ETX-26 from RAD is a compact Ethernet access switch with three Gigabit Ethernet and six
Fast Ethernet ports. Featuring
non-blocking architecture, small form factor, and low power consumption, the device enables wire-speed data
transmission for Layer-2 Ethernet connectivity. It is ideal for providing Ethernet Private Line connectivity and
LAN-to-LAN interworking to small and
medium enterprises.
Supporting Ethernet Ring Protection Switching (ERPS) per ITU-T G.8032, ETX-26
enables link resiliency to ensure high survivability and service continuity in the
event of link failures.
The RAD ETX-26 features an internal bridge that can operate in VLAN-aware or
VLAN-unaware mode. VLAN stacking can be used for traffic separation between different users or services, by defining a
service VLAN ID per customer or service. When VLAN stacking is used, a service VLAN tag is added to user traffic and
removed from network traffic. Both VLAN ID and VLAN priority can be defined for services.
RAD ETX-26 PORT COMBINATIONS
ETX-26 offers flexible Ethernet port combinations:
Six 10/100BaseT Fast Ethernt
One or three Gigabit Ethernet ports with electrical or optical interfaces.
QoS of the ETX-26
Different service types require different levels of QoS to be provided end-to-end.
QoS can be defined per subscriber as well as per service. QoS has two aspects:
rate limitation
traffic prioritization.
ETX-26 supports four priority queues per Ethernet port with configurable scheduling
( strict priority or WFQ). In addition the device supports ingress and egress rate
limiting to control the incoming and outgoing 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, or
best-effort data. In case of congestion, the relevant service receives higher priority at the customer premises.
Traffic can be classified dynamically and mapped 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 REDUNDANCY OF ETX-26
To ensure high survivability and service continuity, ETX-26 features Ethernet ring
protection 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 of link failure.
PROPRIETARY POWER OVER ETHERNET (PoE) ON RAD's ETX-26
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 Power over Ethernet capability can be used to
feed the outdoor unit (ODU) of RAD’s Airmux-200/400 broadband wireless transmission devices, providing a single
indoor device for Ethernet connectivity and ODU power feeding.
DYING GASP
ETX-26 reports power failure (if the unit is connected to AC power), thus enabling
the device to properly disconnect from the network with notification of the reason
for the service problem.
MANAGEMENT OF THE RAD ETX-26
The ETX-26 can be managed using the following 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-based management system.
