ALTER SU Command
TPDUSIZE
specifies, in bytes, the maximum length of a TPDU.
Value: 128 | 256 | 512 | 1024 | 2048 | 4096 | 8192
The values 4096 and 8192 are valid only when the transport protocol class is 1, 2, 3,
or 4.
For X.25 subnetworks: OSI/TS will adjust the value of TPDUSIZE to not exceed
the value of the X25AM SYSGEN attribute MAXIOSIZE. Use the STATUS SU
command to see the actual TPDUSIZE used when the connection was established.
TTRTIMEOUT
specifies the maximum amount of time to try reassignments after network
connection failures. If the value is 0 seconds, no reassignment is performed. Only
nonzero values are transmitted in the CR-TPDU. This attribute is valid only when
the transport protocol class is 1 or 3.
Value: 0.000 through 180.000 (0 through 180 seconds)
TWRTIMEOUT
specifies the amount of time to wait for reassignment after network connection
failures. If the value is 0 seconds, no reassignment is performed. Only nonzero
values are transmitted in the CR-TPDU. This attribute is valid only when the
transport protocol class is 1 or 3.
Value: 0.000 through 180.000 (0 through 180 seconds)
WINDOWTIMEOUT
specifies the amount of time to wait before retransmitting up-to-date window
information. This attribute is valid only when the transport protocol class is 4.
Value: 1.000 through 250.000 (1 through 250 seconds)
X25ACCEPTCHG
specifies whether an incoming call request that contains a request for the recipient to
pay the charge are accepted. ON means that collect calls are accepted. OFF means
that collect calls are not accepted. This attribute is used only for X.25 networks.
Value: ON | OFF
X25BCUG
specifies the bilateral closed user group ID sent in every call-request packet. This
attribute is used only for X.25 networks.
RESET returns this attribute to the #L3 SERVICE X25BCUG value.
Value: 0 through 9999
Default: Defaults to the #L3 SERVICE BCUG value.
