INFO SERVICE Command
Commands and Responses
5–102 056786 Tandem Computers Incorporated
ZCHECK-TSEL
specifies whether checksum fields are added to CC-TPDUs.This attribute is
valid only when ZCLASS is 4. The possible values are:
ZSPI-VAL-TRUE
ZSPI-VAL-FALSE
ZSPI-VAL-TRUE specifies to add checksum fields. The default is ZSPI-VAL-
FALSE.
ZPASV-MUX
specifies indicates the sharing of X25AM SUs for attaching TSP SUs in
anticipation of multiplexing performed by the remote transport entity.The
possible values are:
ZSPI-VAL-TRUE
ZSPI-VAL-FALSE
The default value is ZSPI-VAL-FALSE. If this attribute and the ZMULTIPLEX
attribute are set (ZSPI-VAL-TRUE), the TSP process will assume that the
remote transport entity will multiplex all transport connections destined to the
same X.25 port (same DTE address). In this situation, the TSP process will not
attempt to create an X25AM SU for each transport attach request. This will
greatly reduce the number of X25AM SUs created at the time attach requests
are made. Note, that the assumption is based solely on the X.25 port number
and not the local TSEL.
ZSPI-TKN-RETCODE
indicates whether or not the command was successful. If the command failed, this
token supplies the reason for the failure. Its use is described further in the
Distributed Systems Management (DSM) Programming Manual.
ZSPI-TKN-ERRLIST and ZSPI-TKN-ENDLIST
enclose a standard SPI error list, as described in the Distributed Systems
Management (DSM) Programming Manual.
ZSPI-TKN-CONTEXT
used in returning multiple response messages, is described in the Distributed
Systems Management (DSM) Programming Manual.
Operational Note
The values of the SERVICE attributes are used to set the default values of the
corresponding SU attributes.
