Product SummaryThe RIC-E3/ETH interface converter and RIC-T3/ETH interface converter offer simple, cost-effective connections between E3, T3 services and 10/100BaseT LANs. The RIC-E3/ETH interface converter and RIC-T3/ETH interface converter provide built-in bridging and VLAN support at Ethernet/Fast Ethernet rates, enabling virtual connections of remote LANs (e.g., campus applications). Benefits• Low cost interface configuration • User-configurable • Supports auto-negotiation; plug-and-play Ethernet connectivity Further Product InformationThe RIC-E3/ETH interface converter and RIC-T3/ETH interface converter are a cost-effective alternative to expensive E3/T3-to-Ethernet router interfaces, achieving maximal bandwidth utilization of the E3/T3 link, without the heavy overhead associated with ATM technology. The Ethernet interface module performs frame filtering and forwarding at the Fast Ethernet maximum theoretical rate of 150,000 frames per second without adding delays. The RIC-E3/ETH interface converter and RIC-T3/ETH interface converter forward Ethernet/IP traffic over SDH / SONET networks at full E3, T3 speed. The user can configure the RIC-E3/ETH interface converter and RIC-T3/ETH interface converter to enable or disable broadcasting and IP multicasting to the WAN as required, increasing network efficiency. The RIC-E3/ETH interface converters and RIC-T3/ETH interface converters can be used to connect high-volume routers over E3, T3 links to Internet service providers (ISPs). Using these interface converters, the carrier can connect to the router's low-cost 10/100BaseT port, rather than using an expensive E3, T3 router interface. The converters support auto-negotiation, which allows plug-and-play Ethernet connectivity without any additional configuration. The products are available as standalone units.
