Configuring Expand-Over-ATM Lines
The Expand-over-ATM line-handler process provides connectivity to an Asynchronous
Transfer Mode (ATM) network.
In addition, the Expand-over-ATM line-handler process can use the services of the
ServerNet LAN systems access (SLSA) subsystem to provide Expand-over-ATM
connections.
The ATM subsystem provides a PVC and SVC connection, whereas the SLSA
subsystem provides an ATMSAP with lifname connection that enables you to manage
PVC connections under SLSA. In other words, the ATMSAP connection is identical
with a PVC connection; only the subsystem is different, which could potentially make
your subsystem configuration process easier.
An Expand-over-ATM line-handler process can be configured as a single line, as part
of a multi-line path, or as part of multi-CPU path.
This section explains how to configure an Expand-over-ATM line-handler process as a
single-line or as part of a multi-CPU path. Configuring Expand-over-ATM lines that are
part of a multi-line path is explained in Section 14, Configuring Multi-Line Paths.
Note. Multi-line paths are not recommended. For fault tolerance (i.e. a backup line) a multi-
CPU path (superpath) is the recommended approach.
