XCA major node for host A02 (token-ring LAN)

TYPE=XCA on the VBUILD definition statement indicates that this is an external communication adapter major node.

On the PORT definition statement:

ADAPNO=0 is the adapter number assigned by the 3172.
CUADDR is the device address of the attached LAN. In this case, A02's CUADDR matches A500's CUADDR (CUADDR=BC0).
MEDIUM=RING indicates that this is a token ring connection.
A02's SAPADDR=4 is the SAP address of the connection defined by this major node.

The group named GP2BC1 defines a peripheral node connection to a PS/2 connected to the LAN. DIAL=YES is required for a a peripheral node connection. Group name GP2BC1 matches the GRPNM value on the PATH definition statement in the corresponding switched major node in Attaching a peripheral node over an IBM 3172 Interconnect Controller.

The group GP5BC1 is used to define the subarea node connection to host A500. DIAL=NO on the GROUP definition statement is required for a subarea node connection. USER=SNA on the L5BC11 LINE definition statement specifies that the line uses SNA protocols to access an IBM® 3172 Nways Interconnect Controller for use by the LAN. A02's SAPADDR for PU P5BC11 must match A500's PORT SAPADDR (SAPADDR=8).
