SunATM 622 3U CompactPCI Adapter

The SunATM622 compact PCI adapter is a 622 Mbps ATM network interface board
with a multi-mode fiber optical transceiver for LAN access. The SunATM622
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 622 Mbits/sec.

Hardware Features

■Supports 622-Mbps operation over 62.5/125 µmultimode fiber cable at 1300 nm
wavelength
■Integrates PCI and SAR (segmentation and reassembly) functions in an ASIC
implemented in standard CMOS
■Aligns SAR function with ATMForum specified and International
TelecommunicationsUnion-Telecommunication Sector (ITU-TS) approved ATM
Adaptation Layer (AAL) 5
■Supports 32- and 64-bit bus master interface
■Supports 33 MHz clock speeds
■Supports the SONET and SDH (Synchronous Optical NETwork/Synchronous
Digital Hierarchy) physical layer framing structure
Hardware and Software Requirements
Toconnect the Sun adapter to an ATM switch, you need a multimode fiber cable
with an SC connector.
Refer to the manuals supplied with the ATMswitch for specific instructions about
the switch’s cable connections and cabling an ATMnetwork.
The software drivers required for operating the adapter arelocated on the Solaris
Sun Computer Systems Supplement CD-ROM, which is included with the Solaris
software.
