ATM uses VCs to create individual communication links between
network nodes. ATM uses two types of VCs:
Permanent Virtual Channels (PVCs) are static connections
"
between network nodes that are configured statically.
The nodes of the connection operate as if they are connected
with a dedicated physical line.
Switched Virtual Channels (SVCs) are similar to voice
"
telephone network connections. These are temporary
connections between any two end points on the network and
are configured via signaling. A Switched VC (SVC) is created
dynamically for each session and released when the
information exchange is complete.

Each ATM cell carries two labels called VPI and VCI as part of its
header.
An ATM channel, commonly referred to as virtual channel, is fully
identified by these two labels. Therefore, multiple ATM channels
can reside on your ADSL line.
ATM connections are static, i.e. of type PVC.
