ZINBOUND-TPDU-XSUM-ERR-THLD
is the threshold value that the Transport Layer compares to the counter
ZINBOUND-TPDU-XSUM-ERR. An L4-THLD event is generated whenever
the counter value is nonzero and dividing the counter value by the threshold
value leaves a remainder of zero. The values range from 0 through 65535. If
the threshold is set to 0, events are never generated. The default value is 0.
ZL4-TIMEOUT-THLD
is the threshold value that the Transport Layer compares to the counter ZL4-
TIMEOUT. An L4-THLD event is generated whenever the counter value is
nonzero and dividing the counter value by the threshold value leaves a
remainder of zero. The values range from 0 through 65535. If the threshold is
set to 0, events are never generated. The default value is 0.
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.
ZCOM-TKN-CMD-TIMEOUT
is described in the Communications Management Programming Manual. This token is
optional; duplicate occurrences are not allowed.
