Introduction

1.1 Overview

RIC-155 is a converter that enables simple and efficient connection of Fast Ethernet traffic over STM-1/OC-3c lines. Equipped with a 10/100BaseT and fiber optic or coaxial STM-1 interface, RIC-155 serves as cost-effective alternative to ATM devices and routers. The RIC-155’s packet-over-SONET encapsulation protocol enables virtually total utilization of SDH/SONET payload traffic, since only a small header is required. RIC-155 supports VLAN bridging, flow control and backpressure, according to IEEE 802.3x requirements.
