Whether you want to speed your text and data
transmission or to run distributed multimedia applica-tions, the ATM155-SSC
brings the advantages of ATM network technology to your desktop. With our
network interface card, numerous applications can communicate simultaneously
with their counterparts. The ATM155-SSC network interface card allows
SBus-based systems like SPARCservers® and SPARCstations® to participate
in high speed ATM networks. The ATM segmentation and reassembly device provides
a highly integrated solution for network exhausting applications like real time
CD-quality audio, full-motion video and high-speed data communication.
ATM technology makes your network much faster than shared media networks
like FDDI or even fast ethernet. It ensures that your applications get the
network bandwidth they need.
A SC connector interfaces to a duplex 62.5/125µ
multimode fiber (2 km max.). Other examples of physical media interfaces are
available upon demand.
SBus Interface /AAL5 SAR
All necessary functions for variable bit rate
data transfer (AAL5) are per-formed in the hardware. Transparent AAL0 frame
processing for constant bit rate services can be done by the software.
Located on a single slot SBus card, a segmentation and reassembly device
(SAR) provides optimized ATM cell and AAL5 frame functions.
The architecture of the device supports CBR, VBR and
UBR traffic. Using 128 KByte of local 32 KB control memory, the ATM155-SSC
offers support for up to 255 virtual circuits on the transmit side and up to
1023 virtual circuits on the receive side. Each virtual circuit can be
individually configured concerning bit rate and AAL type.
SONET/SDH Chip (STS-3 /STM-1)
The adapter card contains a single chip
receiver / transmitter for transporting 53-Byte ATM cells at SDH/STM-1 and
SONET/STS-3c data speeds of 155 Mbps. Electromagnetic interference is
significantly reduced by an on-chip clock circuit that generates an output speed
of 155.52 Bit/s from a 19.44 MHz oscillator.
Solaris 2.x Device Driver
The ATM SBus Adaptor provides transparent
support for the classical TCP/UDP/IP protocol stack and a general purpose
programming interface that enables direct access to the ATM-specific network
features. The software is ready to support evolving standards.
ATM cell processing per ANSI T1.627; ITU-T I.361, I.363 and ATM Forum UNI
SBus specification IEEE1496
ATM Forum LAN-Emulation over ATM V2.0 LEC
ATM Forum LAN-Emulation Service optional
The SBus SAR provides an external SBus configuration PROM to
support its initialization and error-handling functions. The PROM can also
beused for device-specific initialization and other booting mechanisms.
Fully compliant with ATM Forum UNI v3.1
Solaris® 2.x operating system support
Supports the new ATM Forum LAN emulation standard for transparent use of
existing ethernet and token ring environments
Supports up to 255 channels on the transmit side and 1023 channels on the
Features ATM Adaptation Layer for variable bit rate services
Onboard SAR chip performs full duplex ATM and AAL processing
Self-identifying single slot SBus card behaves as SBus slave and as direct
virtual memory access master with 32 and 16 byte bursts
High-performance SONET/STS3c and SDH/STM1 physical layer interface
Supports full duplex 155 Mbps data transmission over 62.5/125µ
Dynamically loadable, cloneable, multi-threaded device driver with auto
