of packets that can be outstanding before requiring packet
confirmation. The default is 2. The window size can be negotiated
down to 1 by the called DTE.
Related configuration parameters are:
vSet Default Window
Default Packet Size
Specifies the default requested packet size for SVCs. This value
serves as the lowest negotiable packet size and must be equal to
or less than the maximum packet size specified with the national
set packet-size command. The maximum

default packet size

is
4096 bytes. The default value for this parameter is 128 bytes.

Maximum Packet Size
Specifies the maximum negotiable packet size for SVCs. This value
must be equal to or less than the maximum packet size specified
with the national set packet-size command. The default value for
this parameter is 256 bytes. The maximum value that can be
configured for this parameter is 4096 bytes. This value is utilized in
calculating the maximum frame size for this X.25 interface.

Circuit Idle Time
Specifies the number of seconds that an SVC can be idle before it
is cleared by the router. The range is 0 to 65365.The default is 30
seconds. A0 (zero) specifies that the circuit is never cleared by the
router.
Maximum VCs
Specifies the maximum number of circuits that are open to the
same DTE address for a protocol. Refer to RFC 1356 for
information on utilizing this parameter. The Validrange is 1 to 10.
The default is 4.

See add address command.
The following are QLLC unique parameters:
QLLC response timer
The number of seconds to wait for a Q-response packet
before retransmitting.
QLLC response count
The maximum number of times QLLC will retransmit. Upon
exhausting this number of retries, the upper layer is notified
which may result in the circuit being cleared or reset by the
router.
Accept Reverse Charges
Allows this protocol to override the setting of this National
Personality parameter. This does not affectthe National Personality
parameter.
