NPSI Macro and Operand Descriptions (contd.)
X25.VC.
The X25.VC macro causes a LINE, a PU, and LU macros to be generated for
each logical channel defined in the LCN operand.
LCN Specifies the logical channel number used by the
virtual circuits. If LCNO=USED is specified in
the X25.MCH statement, then LCN=0 must be used.
Default: None
Range: 0-255 (Note that some networks do not use
the value 0).
TYPE Specifies whether this X25.VC statement defines a
switched virtual circuit (SVC) or a permanent
virtual circuit (PVC).
Code TYPE=SWITCHED to define an SVC. If you code
this value, you must also code the OUFINDX keyword,
which points to the X25.OUFT entry that name the
facility set you wish to use for this line.
Code TYPE=PERMANENT to define a PVC. If you code
this value, you must also code the LLC keyword,
which specifies the type of PVC being defined.
Default: None
Range: SWITCHED, PERMANENT
OUFINDX Specifies the index value of the entry in the
Optional Facility Set Table that creates the
facility field and the end of the CUD field in the
Call request packet. This keyword must be
specified if TYPE=SWITCHED. This value must
correlate to the value of the appropriate INDEX
keyword of the X25.OUFT statement.
VCCINDX Specifies the X25.VCCPT statement that describes
the connection parameters to be used by this
virtual circuit. This value must match the
X25.VCCPT index value of the table with the desired
connection parameters.
Default: N/A
Range: 1-99
CALL Specifies whether an SVC is established through an
incoming request or an outgoing request, or through
either type of request.

X25.LINE.
The X25.LINE macro can be used to specify each virtual circuit within a
logical channel group within an MCH. Each X25.LINE macro allows the user
to describe his own PU and LU characteristics using the X25.PU and X25.LU
macros.
LCN Specifies the logical channel number used by the
virtual circuits being defined. If LCNO=USED is
specified in the X25.MCH statement, then LCN=0 must
be coded.

the value 0).
TYPE Specifies whether this X25.LINE statement defines a
switched virtual circuit (SVC) or a permanent
virtual circuit (PVC).
Code TYPE=SWITCHED to define an SVC. If you code
this value, you must also code the OUFINDX keyword,
which points to the X25.OUFT entry that name the
facility set you wish to use for this line.

keyword of the X25.OUFT statement.
LLC Specifies the type of permanent virtual circuit
defined. LLC=LLC3 means that the PVC is attached
to an SNA peripheral node. This keyword must be
specified if TYPE=PERMANENT.

MAXDATA Specifies the maximum frame size (in bytes) allowed
in one data transfer on the link. For a PU type 2
this includes 3 bytes for the RH, and 6 bytes for
the TH. This value depends on the network card
installed on the HP system. NCP parameter

MAXLU Specifies the maximum number of LUs that may be
associated with this PU. Default is the value of
MAXLU operand of the PUDRPOOL or the number of LUs

PATH.
The PATH statement defines a dial-out path to a PU residing in a switched
major node. Up to 256 PATH statements may be defined for each PU.
USE Specifies to VTAM whether or not this path is
initially usable or not. The effect of this
parameter is similar to that of ISTATUS for a
minor node.
Default: YES
Range: NO
DIALNO DIALNO must be specified for SVCs when CALL=OUT or
CALL=INOUT in the X25.LINE statement. It is coded
in the following format:
{ HP X.25 net addr}{ IBM X.25 net addr}{pi}{
VCCINDX} { OUFINDX}
Each field is explained below:
HP X.25 | Specifies the HP X.25 Network
net addr | Address.
|
| Range: 1-15 characters
|
IBM | Specifies the IBM X.25
X.25 net | Network Address. IBM X.25
addr | net addr may be 15
| characters long. HP requires
| that the IBM X.25 Network
| Address be included in the
| DIALNO definition because the
| X.25 Call Packet header is
| checked for the IBM address
| when a call is received at
| the HP system. If the
| address is not included in
| the packet header (because it
| was omitted in the DIALNO
| definition) or if the address
| does not agree with the
| remote address configured in
| the HP configuration, the
| call will be rejected.
|
| Range: 1-15 characters
|
pi | Specifies the protocol used
| over the connection. If this
| value is coded, it must equal
| 3 for HP-IBM SNA X.25
| connections. The value 3
| indicates that the protocol
| is LLC3 (QLLC).
|
VCCINDX | A 2-byte index that
| references an entry in the
| X25.VCCPT macro. The VCCPT
| entries contain parameters
| that are used when the X.25
| connection is established.
|
| Range: 00-99
|
OUFINDX | A 2-byte index that
| references an entry in the
| X25.OUFT macro. The OUFT
| entries define the X.25 user
| facility sets. Thus OUFINDX
| specifies the user facility
| set used when the host dials
| out to the HP 3000.
|
| Range: 00-99
|
GRPNM Specifies the symbolic name of a GROUP statement in
an NCP major node that defines a group of SDLC
switched links. The group referenced must have all
the characteristics necessary to handle the
telephone number, and must be compatible with the
type of physical unit.
PID Specifies the path being defined. This identifier
is unique for a given PU.
Range: 0-255
