addresses and configuration used by the first connection. You specify the SU type
with the ZDEL-TIME attribute. A value of 0 indicates a dynamic SU and a value of -1D
indicates a static SU. Information about a previous connection (including error
information) is available until the static SU is deleted or reused. This is useful for
problem diagnosis.
NSP subdevices (that is, SU objects for X25AM and TLAM) are handled somewhat
differently from TSP (OSI/TS) subdevices. For more information, refer to the
management programming manuals for those underlying subsystems.
ROUTE
A ROUTE object defines a mapping between a network service access point (NSAP)
address and a subnetwork point of attachment (SNPA). A ROUTE object is added
indirectly when a connection is attempted on a subdevice.
Hierarchy of Object Types
Figure 1-4 shows the hierarchy of the OSI/TS object types.

PROCESS
or
null
As shown, the TSP PROCESS object is at the highest point of the hierarchy, with all
other objects subordinate to it. Immediately subordinate to the PROCESS object are
the SERVICE, SU, and ROUTE objects. (The null object type is not shown here because
it is not an actual object type, but is used in commands that do not require
specification of an object type.)
