ZLOC-TSEL
specifies the local transport service access point selector. It is a string of
hexadecimal digits (0 through 9 and A through F) up to a maximum of 64
digits. OSI/TS uses this field to build the calling TSAP-ID field of the
CR-TPDU. If the content of the field is blanks, the CR-TPDU will not contain
the calling TSAP-ID.
ZRMT-TSEL
shows the remote transport service access point selector. It is a string of
hexadecimal digits (0 through 9 and A through F) up to a maximum of 64
digits. OSI/TS uses this field to build the called TSAP-ID field of the
CR-TPDU. If the content of the field is blanks, the CR-TPDU will not contain
the called TSAP-ID.
ZTCON-PRI
shows the priority of the transport connection. This attribute is used to
reassign transport connections after errors have occurred. Because an
agreement has not yet been reached among the implementors concerning this
attribute, Tandem OSI does not currently process this field. The values range
from 0 through 32767 (0 being the highest priority).
ZL4-WIN
shows 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
shows the 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.
