ATM Component Description

The Asynchronous Transfer Mode (ATM) component contains networking support using ATM devices. There are four ATM communication modes:

  • Using local area network (LAN) emulation, known as ATMLANE. This is the mode typically used in corporate LANs.
  • Using Ethernet-permanent virtual circuit (PVC), known as ATMEPVC. This is used in certain ATM-DSL deployments.
  • Using Classical Internet Protocols (IP) over ATM, known as ATMARPC and ATMARPS. This is an alternative LAN technique suitable for IP-only networks.
  • Using Winsock over raw ATM connections. This is used for special purpose applications .

Component Configuration

ATMLANE, ATMARPC, ATMARPS and Winsock do not require configuration when used over ATM.

The following table shows the settings for Ethernet-PVC configurations.

Property/setting name Default setting Description Property example Setting example
VPI 0 The virtual path identifier for the PVC on which the driver operates. VPI 1
VCI 0 The virtual circuit identifier for the PVC. VCI 100
Encap 2 Defines the encapsulation used for data transfer. Possible values are:

0 – IPv4

1 – IPv4 LLC/SNAP

2 – Ethernet

3 – Ethernet LLC/SNAP

 Encap 1

Special Notes

ATM networks commonly use only one of the four possible operation modes listed above.
