RIC-LC from RAD is a Fast Ethernet over E1 converter that provides simple, efficient and
cost-effective Fast Ethernet connectivity over one, four, eight or sixteen bonded E1
circuits. The RIC-LC enables service providers to supply high-capacity Ethernet services to remote locations and
transparently connect corporate LANs over existing E1 links.
RIC-LC supports standard Next Generation Ethernet over PDH protocols including GFP
ITU-T G.8040, VCAT ITU-T G.7043 and LCAS ITU-T G.7042. These protocols allow service providers to dynamically allocate
bandwidth to their customers by mere changing the number of links bonded to the virtual group, without stopping the
service. The RIC-LC can be used in a point-to-point application or in a hub-and-spoke
topology, operating with RADís Egate-100, Egate-2000 and RICi-16 or third-party
Typical applications include:
- Ethernet private Line/LAN services
- IPDSLAM, cellular IP, and WiMAX base station backhauling
- Interoffice or enterprise LAN connection.
Using interface bonding, RIC-LC creates a scalable, large virtual pipe comprised of up
to four, eight or sixteen E1 lines. The bonding is performed at the E1 level,providing flexible bandwidth for different
RIC-LC TRAFFIC SEPARATION VLAN tagging and stacking at ingress and egress enable transporting user traffic
transparently, keeping all the user VLAN settings intact. Management traffic and
user Ethernet traffic are sent together on the same Ethernet flow and can be separated by different VLANs, thus
ensuring high traffic security. QUALITY OF SERVICE (QoS)
RIC-LC supports VLAN-aware and VLAN unaware bridging, as well as VLAN stacking (Q-in-Q). It maps Ethernet frames into
four priority queues based on user port, VLAN priority (802.1p) or DSCP marking,
to enable differentiation between various user applications. It uses both Strict
Priority and WFQ (weighted fair queuing), as well as per port rate limitation.
INTERNAL BRIDGE OF RAD RIC-LC
The internal bridge can be configured to filter or transparent mode. In filter mode,
the bridge learns MAC addresses and filters local traffic accordingly. In transparent mode it forwards the received
packets, ignoring the MAC addresses.
RIC-LC can be managed locally via an ASCII terminal connected to RS-232. Remote inband management is performed
via the E1 ports using Telnet, Web browser or RADview, RADís SNMP-based management system that ensure safe and
secure access control.
Out-of-band management is performed via one of the user Ethernet ports.
LOOP DETECTION E1 loops are immediately detected when they occur, avoiding the resulting Ethernet
loops and Ethernet storms. The RAD-LC automatically recovers when the TDM loop clears. FAULT PROPAGATION
If a failure is detected on the E1port, the fault propagation mechanism deactivates
the Fast Ethernet links, enabling routers and switches on both ends of the link to
reroute the traffic.
RIC-LC diagnostic capabilities include:
- Ping test for checking IP connectivity
- User-activated diagnostic loopback tests on VCG or individual E1 generated using management
software or rear-panel DIP switch.
