TR3271 Management Programming Manual

ELEMENTS OF SPI MESSAGES FOR THE SUBSYSTEM
Command Numbers
Although all data-communications subsystems must use symbolic
names of the form ZCOM-CMD- name , each subsystem defines which
command numbers it supports. The TR3271 subsystem supports the
following commands:
ABORT LOAD
ADD RESET
ALTER RESETSTATS
CONNECT START
DELETE STATISTICS
DISCONNECT STATUS
GETVERSION STOP
INFO SWITCH
LISTOBJECTS TRACE
These commands are described in Section 6, "Commands and
Responses."
Object Types
Object-type numbers represent the object type (class) of an
object. The value of the object-type number is subsystem-
specific and has a symbolic name. The symbolic name of the value
is of the form ZCOM-OBJ- type , where type identifies the object
type. For example, ZCOM-OBJ-SU identifies the subdevice object
type in data-communications subsystems, including the TR3271
subsystem.
Note that object-type numbers are part of the header of each
command and response. The header token named ZSPI-TKN-OBJECT-
TYPE contains the object-type number. However, if there are
multiple objects in a response or an object is returned within
a data list, an object-type number is contained in the ZCOM-TKN-
OBJTYPE token. The symbolic name of the value is also of the
form ZCOM-OBJ- type , where type identifies the object type.
The TR3271 subsystem supports the following object types:
PROCESS
LINE
SU
NULL
The objects controlled by the TR3271 subsystem are organized in
a hierarchy by object type. In descending order, the hierarchy
is PROCESS, LINE, and SU. The NULL object type is not within
the hierarchy and applies to only two commands, GETVERSION and
LISTOBJECTS.
