056786 Tandem Computers Incorporated 5–97
attribute, Tandem OSI does not currently process this field. The values range
from 0 through 32767 (0 being the highest priority).
ZL4-WIN
specifies the initial credit allocation to the remote transport entity. This is the
number of TPDUs that can be sent by the remote transport entity without
acknowledgment. This attribute is valid only when ZCLASS is ZOS4-VAL-
CLASS-1, ZOS4-VAL-CLASS-2, ZOS4-VAL-CLASS-3, or ZOS4-VAL-CLASS-4.
When ZCLASS is 1, you must specify 0 or 1 (a value of 0 is interpreted as 1).
For transport class 1, the use of values 2 through 15 could lead to a deadlock
situation when the sending transport entity waits for the acknowledgment of
each DT-TPDU before it sends the next one. The range of values is 0 through
15.
ZNETTYPE
specifies network services in terms of quality. Possible values are:
ZOS4-VAL-NETTYPE-A
Network connection with an acceptable residual error rate: not signaled
by disconnect or reset, with an acceptable rate of errors.
ZOS4-VAL-NETTYPE-B
Network connection with an acceptable residual error rate: not signaled
by disconnect or reset, with an unacceptable rate of errors.
ZOS4-VAL-NETTYPE-C
Network connection with an unacceptable residual error rate.
ZCLASS
is the preferred transport protocol class to be used. The values for this field
are:
ZOS4-VAL-CLASS-0
ZOS4-VAL-CLASS-1
ZOS4-VAL-CLASS-2
ZOS4-VAL-CLASS-3
ZOS4-VAL-CLASS-4
The default value for ZCLASS is determined by the values of ZNETTYPE and
ZMULTIPLEX, as follows:
ZNETTYPE ZMULTIPLEX ZCLASS
A TRUE 2
A FALSE 0
B TRUE 3
B FALSE 1
