Leased connections between APPN nodes

A leased connection can be used to connect a composite network node to a composite network node or to other nodes that support leased connections. Figure 1 shows a leased connection.

The following examples show how to connect two composite network nodes.

Connect the NCP major node for the first host as follows:
GRP4A6   GROUP LNCTL=SDLC,DIAL=NO,MODE=SEC,TYPE=NCP,                   X
               CLOCKNG=EXT,DUPLEX=HALF,SPEED=1200
*
LN4A6    LINE  ADDRESS=04E, TADDR=C1
*
         SERVICE ORDER=(P4A4956C)
*
P4A4956C PU    PUTYPE=2,XID=YES,                                       X
               MAXDATA=256,MAXOUT=1,PASSLIM=1,                         X
               ANS=CONTINUE,CONNTYPE=APPN,CPCP=YES
Connect the NCP major node for the second host as follows:
GRP3A9   GROUP LNCTL=SDLC,DIAL=NO,TYPE=NCP,                            X
               CLOCKNG=EXT,DUPLEX=HALF,SPEED=1200
*
LN3A11   LINE  ADDRESS=03F
*
         SERVICE ORDER=(P3A4956M)
*
P3A4956M PU    PUTYPE=2,ADDR=C1,XID=YES,                               X
               MAXDATA=256,MAXOUT=1,PASSLIM=1,                         X
               ANS=CONTINUE,CONNTYPE=APPN,CPCP=YES
