VTAM® attaches to
ATM networks through native ATM access through an Open Systems Adapter. VTAM can communicate with HPR APPN
nodes over ATM native connections. Communication occurs over the following
types of connections:
- Transmission groups (TGs) over permanent virtual channels (PVCs),
DIAL=NO
- TGs over switched virtual channels (SVCs), DIAL=YES
- TGs to connection networks, DIAL=YES
To define an external communication adapter major node
for an ATM native connection, code the VBUILD and PORT definition
statements followed by GROUP, LINE, and PU definition statements to
define the TGs.
