Features

10/100BaseT Interface

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.

STM-1/OC-3c Interface

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

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