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
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
• 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
