ATM Tranparent Multimedia Interface Specification
(ATMIS?) ATMIS? is an interface between the ATM device driver and the upper SW stack. It is located between the AAL layer and upper layers
respective the ATM reference model. This interface enables very fast data
transport especially for ATM traffic beside the usual TCP/IP stack.
The ATMIS? interface makes PSC the ideal ATM adapter card for high
bitrate and/or realtime Multimedia data.
PCI Interface AAL5 SAR
All necessary functions for variable bit rate data transfer (AAL5 and AAL3/4) are performed in the hardware. Transparent AAL0 frame processing for constant bit rate services is executed in hard- and software. Located on a half-size PCI card, the segmentation and reassembly device provides optimized ATM cell and AAL5, AAL3/4 and OAM frame functions.Windows/NT Driver
The Microsoft Windows NT®-based ATM software offers trans-parent support
for the NDIS 3.0® protocol stack and a general purpose program-ming
inter-face that provides direct access to the ATM specific network features. The
software is ready to support evolving standards.
SONET/SDH Chip (STS-3/STM-1)
The adaptor 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 a system clock of 155 MHz from a 19 MHz oscillator.SC Duplex Transceiver
A SC connector interfaces to a duplex 62.5/125µ multimode fibre (2 km max.). Other examples of physical media interfaces are available upon demand.PCI-Configuration
The PCI SAR provides internal PCI configuration registers to support its initialization and error-handling functions.Standards Compliance
Environment
Our network interface cards should be considered as a basic solution that we will adapt to your environment. No matter if your network infrastructure consists of copper wiring or if you need a specific interface on ATM for your preferred application, we will provide you with the optimal access to broadband networking.
Control Memory
The architecture of the device supports VBR and UBR traffic. Using 256 KByte of local control memory, the ATM155-PSC offers support of up to 1023 virtual circuits on the transmit side and up to 1023 virtual circuits on the receive side. Each virtual circuit can be individually configured for bit rate and AAL type.Host RAM
For data transfers, the device accesses direct memory access master transfers with 32 and 16 byte bursts. Host memory data buffers are efficiently managed by descriptor rings and scatter-gather data transfers. The software device driver provides a packet-level interface and makes ATM functionality trans-parent for the user.
Technical Specifications
The ATM155-PSC is compatible to any PCI-based platform equipped with one available, fully-PCI compliant slot and running under Windows NT 3.5®. It requires at least a 486 processor and 16 MBytes of memory.
