The SunATM155 CompactPCI adapter is a 155 Mbps ATM network interface board
with a multi-mode fiber optical transceiver for LAN access. The SunATM155
compact PCI adapter provides full duplex transmission of data between a host on a
compact PCI (cPCI) bus and the fiber optics with a data rate of 155 Mbits/sec.
