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 75Ω BNC 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.
