RIC-LC

Ethernet Converter for Multiple PDH Circuits

RAD’s RIC-LC is a Fast Ethernet over E1 converter that provides simple, efficient and cost-effective Ethernet connectivity over up to 16 bonded E1 links. As an Ethernet converter for multiple PDH circuits, the RIC-LC enables service providers to supply high capacity Ethernet services to remote locations over existing TDM infrastructure. Deployed in point-to-point or hub-and-spoke topologies, it operates opposite Ethernet over TDM demarcation devices and aggregators, such as RAD’s RICi-4/8/16E1 and Egate-100, as well as opposite third-party gateways that support Ethernet over NG-PDH encapsulation and bonding techniques.

The RIC-LC Ethernet converter for multiple PDH circuits is an ideal solution for Ethernet private Line and Ethernet private LAN services, inter-office connectivity, and IP DSLAM, IP NodeB and WiMAX base station backhaul over PDH access networks.

Ethernet over NG-PDH encapsulation and bonding

The RIC-LC supports standard Ethernet over NG-PDH protocols, including GFP (generic framing procedure), VCAT (virtual concatenation) and LCAS (link capacity adjustment scheme). These protocols allow service providers to dynamically allocate bandwidth to their customers by simply changing the number of links bonded to the virtual group, without stopping the service.

Ethernet capabilities

Featuring four Fast Ethernet user ports, the 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 ToS marking, to enable differentiation between various user applications. The RIC-LC supports both Strict Priority and WFQ (weighted fair queuing), as well as per-port rate limitation.

Management options

The device features the following management alternatives:

Local management via an ASCII terminal (RS-232)
Out-of-band management using one of the user ports
Remote inband management via the network ports using a dedicated management VLAN
Remote configuration and monitoring accessible via RADview-EMS, RAD’s element management system
Access and management options include Telnet, SNMP, Web server, and TFTP
