RICi-E3 Fast Ethernet over E3 Intelligent Converter
RICi-E3 has one unframed E3 and one 10/100BaseTx port. Packets are forwarded from the Ethernet network to the E3 network at wire speed, fully utilizing the expensive E3 circuit.
RICi-E3 is available with temperature-hardened enclosures that extend the operating temperature range.
ETHERNET
Internal Bridge
The internal bridge handles 1536-byte frames supporting VLAN applications. In filter mode, the bridge learns MAC addresses and filters local traffic, and in transparent mode, it forwards any received packet.
QoS
The priority scheme (IEEE 802.1p) enables users to define three different QoS levels, according to the application requirements.
The DHCP client automatically obtains the IP address, IP mask, and default gateway, minimizing installation time.
Separating Ethernet Traffic
VLAN stacking transports user traffic transparently, keeping the user LAN settings intact. In addition, the management traffic may be tagged with a different VLAN tag, fully separating user traffic from management data.
RESILIENCY
The units feature fault propagation. When RICi-E3 or RICi-T3 detects a link failure, it shuts down the user port.
MANAGEMENT AND SECURITY
RADview, RAD’s SNMP-based system provides fault management and monitoring.
The devices can also be managed via an ASCII terminal or Telnet.
Inband management is performed from the Fast Ethernet user port or via the E3 or T3 port. Management traffic and user Ethernet traffic are transported together on the same Ethernet flow, separated by different VLAN tags to ensure traffic security.
MONITORING AND DIAGNOSTICS
Remote and local loopbacks are used for problem isolation at the physical layer.
A built-in ping utility allows checking IP connectivity by pinging remote IP hosts.
A traceroute application quickly maps a route from RICi-E3 to any other network device.
The units feature fault propagation. When RICi-E3 detects a link failure, it shuts down the user port.

RICi-E3 are intelligent converters connecting Fast Ethernet LANs over E3 circuits. They enable service providers and ISPs to supply transparent Ethernet services, without interfering with user traffic.
- Transparent user traffic and secure management, via double VLAN tagging
- Three levels of QoS, based on VLAN priority queues as per IEEE 802.1p
- Inband and out-of-band management
- Monitoring and statistics collection of TDM and Ethernet ports
- Fault propagation of E3 error conditions to the Ethernet port
