Introduction
1.1 Overview
RIC-E3/ETH and RIC-T3/ETH are interface converters, which convert between
unframed E3/T3 data and 10/100BaseT Ethernet. RIC-E3/ETH and RIC-T3/ETH
offer simple and cost-effective interconnection between 10/100BaseT LANs and
E3/T3 services, making distant LANs operate as one local network.
Versions
Two converter models are available:
• RIC-E3/ETH: E3 to 10/100BaseT converter
• RIC-T3/ETH: T3 to 10/100BaseT converter.
Power Options
• AC power supply: 100 to 240 VAC
• DC power supply: -48 VDC.
Applications
RIC-E3/ETH and RIC-T3/ETH provide logical connection of the distant LANs, as
shown in Figure 1-1.
