ATMworks 350L Adapter

This document provides a comprehensive guide for installing and configuring the Digital Equipment Corporation ATMworks 350L adapter card in personal computers running Windows NT 3.51 or later, specifically with Intel 486 or Pentium processors.

The guide covers hardware installation, detailing the physical process of inserting the single-slot adapter into a PCI/EISA bus slot, emphasizing anti-static precautions, and conducting initial diagnostics using the DOS-based decdiag utility. It also provides instructions for correctly attaching optical (SC) or Unshielded Twisted Pair (RJ45) cables and includes detailed technical specifications for both multi-mode fiber and Category 5 UTP versions of the adapter.

For software installation and configuration, the document outlines the procedure using the Windows NT Control Panel. It explains various configuration parameters such as the Slot Number, UNI Version (3.0 or 3.1), Cell Frame Type (SONET or SDH), and Empty Cell Type (Idle or Unassigned). A significant portion is dedicated to LAN Emulation (LANE) through ATM, which allows Ethernet or Token Ring traffic to operate over an ATM network. This section details the components of LANE (LAN Emulation Client (LEC), Configuration Server (LECS), Server (LES), and Broadcast Unknown Server (BUS)) and guides users through configuring LECs, including assigning MAC addresses, specifying LECS addresses, and setting ELAN names. The document also provides steps for assigning IP addresses and subnet masks to the ATMworks 350L.

Finally, it includes instructions for removing, moving, and updating the adapter's software. Verifying operations is discussed through the Windows NT Event Viewer, with an extensive Appendix detailing various event messages related to ILMI, QSAAL, Q93B, LEC, and AAL, along with their indications and suggested troubleshooting actions. The ATMworks 350L is described as a high-performance 155.52 Mbps adapter that uses a custom ASIC to implement AAL5 protocol and supports various ATM traffic types, physical layers, and features like per VC rate control and early packet discard.
