RIC-LC 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 device 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.

HARDWARE OPTIONS

RIC-LC is provided with two hardware options:

• RIC-LC with 1-16 E1 ports and aninternal power supply
• RIC-LC with a single-E1 port and an external power supply.

INTEROPERABILITY

The device can be used in a point-to-point application or in a hub-and-spoke topology, operating with RAD’s Egate-100, Egate-2000 and RICi-16 or third-party gateways.

MARKET SEGMENTS AND APPLICATIONS

RIC-LC targets cost-sensitive applications for carriers, mobile operators and service providers, such as transparent inter-LAN connectivity, Ethernet private lines, as well as IP DSLAM, WiMAX base station and
cellular backhaul.

ETHERNET

VLAN tagging and stacking

VLAN tagging and stacking at ingress and egress enable transporting user  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

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.

MANAGEMENT AND SECURITY

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, RAD’s SNMP-based management system that ensure safe and secure access control.
Out-of-band management is performed via one of the user Ethernet ports.
