RIC-155 Installation and Operation Manual 

1-2 Overview

 

 

RIC-155 Fast Ethernet interface operation conforms to the IEEE 802.3u, 802.3x 
and 802.1p standards, including VLAN applications. The Fast Ethernet interface 

supports the following functions: 
•  Four levels of QoS, according to ToS or 802.3p 
•  High performance lookup engine with support for up to 1024 MAC address 

entries with automatic learning and aging 

•  Autonegotiation 
•  Backpressure 
•  Half duplex and full duplex operation 
•  FDX flow control 
•  Automatic MDI/MDIX crossover. 

RIC-155 converts Ethernet/Fast Ethernet signals into POS and vice. The  
STM-1/OC-3c interface terminates into fiber optic or 75Ω BNC coaxial 
connectors. Single mode fiber optic interface of the unit uses a 1310 nm LED or 
1310/1550 laser diode transmitters (see 

The STM-1/OC-3c interface of RIC-155 operates with internal or receive clock.
