New PMC ATM Network Interface Card

Raleigh, NC, March 2013 Beyond Electronics, a technology leader providing rugged, real-time computing solutions to OEMs and system integrators, has introduced a new PMC ATM Network Interface Card (NIC) that provides compliance with Wide Area Network (WAN) standards. The new OC-3 PMC ATM NIC is designed to relieve obsolescence problems by using new technologies to replace aging ones. The product is register compatible with legacy Integrated Device Technology IDT77211A hardware thus reducing software, integration and test costs incurred in maintaining or upgrading existing platforms. Most legacy system deployments will require little to no change in system or application software.

The NIC is designed using a combination of a general purpose communications processor coupled with a high density CPLD. This combination so closely mimics the original hardware that a system cannot distinguish the difference from the legacy product except by interrogating some of the added feature registers or by examining the EPROM based product signature.

To further support legacy systems, an optical interface has been designed that enables connection to DIN LSA 47256 (IEC 61754-3 ed 1.0) terminated fiber. As with the NIC, the implementation utilizes new technologies, including the design of stainless steel replacement connectors.

The new OC-3 PMC-ATM NIC currently supports CBR and UBR service classes and has the infrastructure in place to support VBR and ABR. It has been tested with most popular TCP/IP protocols (Classical-IP, ATM Forum LANE). The PMC-ATM has demonstrated compatibility with software and drivers available on VxWorks from WindRiver Systems as well as Linux. Built in test is also provided with the product allowing high coverage testing to be performed in system ensuring reliable operation.

To offer an upgrade path to Ethernet for deployed systems, the PMC-ATM can be programmed to act as a “transparent” media converter. The host system continues to run existing ATM drivers while the physical media and external protocol is converted to Ethernet.

The PMC-ATM is available in various environmental grades. It has been fully qualified for military applications including: shock/vibration, altitude, pressure rate of change, temperature, temperature rate of change, noise injection, etc.

The new OC-3 PMC-ATM NIC has already been deployed, is in service and is available immediately.
