the connection. Acceptable values range from 300 (3 seconds) through 18000
(180 seconds).
ZX25PVC
specifies the channel number of the permanent virtual circuit (PVC) with
which the X25AM subdevice to be created is bound. The value of ZX25PVC
must be compatible with the values of the X25AM attributes PVCRANGE and
SVCRANGE. Refer to the X25AM Management Programming Manual for
information about how to set up an X.25 line as a PVC line. The range is 1 to
4095. For TRANSPAC networks, the range is 0 through 4095. To reset this
field to its default value, set the first byte to ZOS4-VAL-PVC-RESET.
ZIP-NULL-LAYER
enables or disables the generation of the null network layer (inactive subset)
protocol header. This attribute is valid only when ZCLASS is ZOS4-VAL-
CLASS-4. This attribute is used only for LAN networks.
ZIP-X25-SNDCF
specifies whether the subnetwork conversion function (SNDCF) is to be used.
This attribute is used only for X.25 networks. If set to ZSPI-VAL-TRUE,
SNDCF is enabled; if set to ZSPI-VAL-FALSE, SNDCF is disabled.
ZX25CUG-TYPE
specifies the type of closed user group (CUG) facility. This attribute is used
only for X.25 networks. The possible values are:
Value Meaning
ZOS4-VAL-X25CUG-TYPE-BASIC Basic CUG format
ZOS4-VAL-X25CUG-TYPE-EXT Extended CUG format
ZOS4-VAL-X25CUG-TYPE-BASICOA Basic CUG format with outgoing access
ZOS4-VAL-X25CUG-TYPE-EXTOA Extended CUG format with outgoing access
If no value is provided for ZX25CUG, ZX25CUG-TYPE will default to ZOS4-
VAL-X25CUG-TYPE-BASIC. If ZX25CUG is 0 to 99, ZX25CUG-TYPE can be
any of the four values, and will default to ZOS4-VAL-X25CUG-TYPE-BASIC.
If ZX25CUG is 100 to 9999, ZX25CUG-TYPE must be ZOS4-VAL-X25CUG-
TYPE-EXT or ZOS4-VAL-X25CUG-TYPE-EXTOA, and will default to ZOS4-
VAL-X25CUG-TYPE-EXT. If you do not provide a value, the value of the
CUGTYPE attribute in X25AM is used.
ZX25BCUG
specifies the bilateral closed user group ID sent in every call-request packet.
This attribute is used only for X.25 networks. The value is an integer from 0
through 9999. No default value is provided. If you do not provide a value,
the value of the BCUG attribute in X25AM is used.
