1. Introduction

  This README file describes the new features in the Integrated Driver 1 (ID1)
  release of the ATM adapter software. This file should be read carefully
  before the ID1 software is installed on your system. The ID1 driver provides
  the following functions in the same driver. All these functions can be
  enabled and used simultaneously.

    - LAN Emulation client (SVC).
        o Ethernet
        o Token Ring

    - LAN Emulation services (LES, BUS and LECS).
        o Ethernet
        o Token Ring

    - IP-ATM (RFC-1577) client (SVC)

    - IP-ATM (RFC-1577) server

    - Bridged PVCs based on RFC-1483
        o LLC Encapsulated Ethernet/802.3
        o LLC Encapsulated 802.5
        o Null Encapsulated Ethernet/802.3
        o Null Encapsulated 802.5
     
    - Routed PVCs based on RFC-1483
        o LLC Encapsulated
        o Null Encapsulated

  The configuration and the statistics display of the driver software is done
  with a GUI based utility, CellView.


2. Installation

   The driver needs to be installed through the Network Control Panel Applet.
   The path to the driver files is <drive letter>:\PPC_WinNT where <drive
   letter> is the drive letter name of your CD-ROM drive.

4. Configuration

  After the software is installed on a system and the softfware is configured
  with CellView, the system should be rebooted. Once the software is
  configured, it does not have to be configured again after each system reboot.


5. CellView

  CellView is a GUI based utility for ATM software configuration and statistic
  display. When an entity, such as LECS, is configured with CellView, in
  addition to configuring the software, the configuration information is
  stored in the configuration file so that upon subsequent system reboots, the
  software configuration can be restored without having to configure the
  software manually again. At the system boot time, all the software entities
  are initialized with the configuration information in the configuration file.

  In the "Setup" mode, CellView displays the configuration stored in the
  configuration file. In the "Stats" mode, CellView displays the actual
  configuration of the software. Normally the configuration file mirrors the
  software configuration.
  

6. PVCs

  The LAN Emulation and IP-ATM clients include both SVC and PVC capabilities.

  In LAN Emulation clients, SVC capabilities are based on ATM Forum's "LAN
  Emulation Over ATM Specification - Version 1.0". The PVCs supported are
  bridged PVCs as described in RFC-1483. Clients can be enabled in PVC only or
  PVC and SVC mode. A 6 byte unicast MAC address and a VCI number is associated
  with each PVC. Packets received from the upper layers whose destination MAC
  address match the MAC address of a PVC are transmitted on that PVC. Each PVC
  can be individually enabled as "Broadcast PVC". If enabled as "Broadcast
  PVC", all the broadcast/multicast packets received by that client from the
  upper layers are transmitted on that PVC. A maximum of 16 PVCs can be enabled
  as "Broadcast PVC".

  In IP-ATM clients, SVC capabilities are based on RFC-1577. The PVCs supported
  are routed PVCs as described in RFC-1483. Clients can be enabled in PVC only
  or PVC and SVC mode. An IP address and a VCI number is associated with each
  PVC. Packets received from the upper layers whose first hop (an end-station
  or a router) match the IP address of a PVC are transmitted on that PVC. Like
  RFC-1577, IP-ATM PVCs do not support transmission of broadcast/multicast
  packets. 


7. Other Notes

   - MAC address for Bridged PVCs should be entered in the natural order of
     the emulated LAN. For Ethernet emulation, the MAC address should be
     entered in the conical format. For Token Ring emulation, MAC address
     should be entered in the non-conical format.

   - After the software package is installed, all the entities, except LAN
     Emulation client 0, are initially configured as disabled. Run CellView
     to enable and configure desired entities.
     
   - Set "Enable Advanced Settings" in the "Global" dialog box in CellView to
     access LAN Emulation services from CellView. 


8. Bug (missing features) list

   - The drivers do not support multiple LAN Emulation clients on the
     same ELAN.
 
   - NetBEUI does not work over Token Ring LAN Emulation.
