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.
ZOSI-MAP-ALTER-SERV-L5
is an extensible structured token that contains attributes of the Layer 5 SERVICE
being altered. ZOSI-DDL-ALTER-SERV-L5 contains the following fields:
ZDISCONN-TIMER
is the maximum amount of time the session service provider should wait for a
transport-disconnect indication after issuing a request for session release or
abort service. If a transport-disconnect indication is not received within this
time interval, the session service provider issues a transport-disconnect
request. The waiting time is expressed in microseconds (0.000001 seconds per
increment). Acceptable values for this field range from 1,000,000 (1 second) to
300,000,000 (300 seconds). The value initially set by the OSI manager is
3,000,000 (3 seconds).
ZVSN1
specifies whether the application using this PROFILE can operate over a
session protocol version 1 connection. If this field is set to ZSPI-VAL-TRUE,
the application can operate over protocol version 1; if it is set to ZSPI-VAL-
FALSE, the application cannot operate over protocol version 1. At least one of
the two protocol version fields (ZVSN1 and ZVSN2) must be set to ZSPI-VAL-
TRUE. The value initially set by the OSI manager for ZVSN1 is ZSPI-VAL-
TRUE.
ZVSN2
specifies whether the application using this PROFILE can operate over a
session protocol version 2 connection. If this field is set to ZSPI-VAL-TRUE,
the application can operate over protocol version 2; if it is set to ZSPI-VAL-
FALSE, the application cannot operate over protocol version 2. At least one of
the two protocol version fields (ZVSN1 and ZVSN2) must be set to ZSPI-VAL-
