Sun (Sun Microsystems, Inc. ) : ATM 622

SunATM 2.0 SBus Adapter

SunATM adapters are single-wide SBus cards that conform to ATM Forum Specifications. One implementation offers 155Mbps network bandwidth over multimode fiber and the other supports category 5 Unshielded Twisted Pair (UTP) wiring. Product Features include

• Supports 155Mbps operation over multimode fiber or category 5 UTP wiring
• Supports SONET/SDH physical layer framing
• Enables TCP/IP applications to run transparently over ATM (IETF RFC 1577 )
• Supports LAN Emulation (ATM Forum LANE 1.0 Specification)
• Supports User Network Interface (ATM Forum UNI 3.0/3.1 Specification)
• Offers Sun interim ATM APIs for signalling and raw AAL5 frame transfer
• Gives "wirespeed" performance in standard TTCP test environment
• Implements SAR (Segmentation And Reassembly) function aligned with AAL 5 (ATM Adaptation Layer 5, pioneered by Sun and endorsed by LAN manufacturers and ITU)
• Up to 128 transmit channels and up to 1024 open receive channels
• Offers 64bit SBus and 64byte bursts support, conforming to IEEE 1496
• Provides SNMP Agent for interface to standard management systems
• Integrated SBus/SAR ASIC SAHI3 (SBus to ATM Host Interface) implemented in CMOS
• Compatible with relevant emerging standards, including ATM Forum baseline specifications
