Example of an XCA configuration in a single-domain environment, including an IBM 3172 Nways Interconnect Controller.

For the configuration in Figure 1, code the following statements:

An XCA major node to represent the PU in the IBM 3172 Nways Interconnect Controller:

XCACON1  VBUILD TYPE=XCA               XCA MAJOR NODE
PORT1    PORT  MEDIUM=BOXMGR,          3172 MANAGER
               CUADDR=500              CHANNEL UNIT ADDRESS
*
GROUP1   GROUP ISTATUS=ACTIVE          ACTIVATED AT GEN
LINE1    LINE
PU1      PU

Another XCA major node for the token ring:

XCACON2  VBUILD TYPE=XCA               XCA MAJOR NODE
PORT2    PORT  MEDIUM=RING,            TOKEN-RING
               SAPADDR=4,              SERVICE ACCESS POINT ADDRESS
               ADAPNO=1,               ADAPTER NUMBER
               CUADDR=BC0              CHANNEL UNIT ADDRESS

GROUP2A  GROUP DIAL=YES,               SWITCHED PERIPHERAL NODE
               CALL=INOUT,             CAN DIAL IN OR OUT
               ISTATUS=ACTIVE          ACTIVATED AT GEN
LINE2A   LINE  ANSWER=ON               PU CAN DIAL IN
PU2A     PU
GROUP2B  GROUP DIAL=YES,               SWITCHED PERIPHERAL NODE
               CALL=INOUT,             CAN DIAL IN OR OUT
               ISTATUS=ACTIVE          ACTIVATED AT GEN
LINE2B   LINE  ANSWER=ON               PU CAN DIAL IN
PU2B     PU

A switched major node for the two peripheral nodes attached to the LAN:
