X.25 pkt size The default (128) maximum, and minimum number of bytes in the
data field of a data packet.
X.25 Min pkt size Minimum number of bytes in the data field of a data packet when
negotiating the packet size with a remote X.25 switch.
X.25 Max pkt size Maximum number of bytes in the data field of a data packet when
negotiating the packet size with a remote X.25 switch. Note that a
large packet size improves throughput by reducing the overhead
associated with header transmission. However, a large packet size also
increases the probability of transmission errors, causes increased
transmission delays on the network, and is associated with processing
delays at the host.
X.25 lowest PVC The X.25 Lowest PVC and X.25 Highest PVC parameters define a
range of PVCs from 1 to 4096. If the lowest PVC number is zero, no
PVCs are supported.
X.25 highest PVC
X.25 lowest SVC
The X.25 Lowest SVC and X.25 Highest SVC parameters define a
range of SVCs from 1 to 4096. If the lowest SVC number is zero, no
SVCs are supported.

X.25 Clear/Diag Whether or not Clear-Request packets include the diagnostic field. The
default is No.
X.25 Reset/Diag Whether or not Reset-Request packets include the diagnostic field.
The default is No.
X.25 Restart/Diag Whether or not Restart-Request packets include the diagnostic field.
The default is No.
X.25 Options None (no options) or NPWS (specifying that the MAX negotiates
packet and window size). The default is None.
X.25 Rev Charge
Accept
Whether or not the MAX accepts packets that request charge reversal.
The default is No.
X.25 Network Type Type of network used by the link. At present, the MAX supports only
the CCITT network type.
X.25 T20 The duration of the Restart timer (the number of one-second ticks the
MAX waits before retransmitting a Restart-Request packet).
X.25 R20 The number of Restart-Request retransmits the MAX sends before
waiting indefinitely for a response.
X.25 T21 The duration of the Call-Request timer (the number of one-second
ticks the MAX waits before clearing an unacceptable outgoing call).
X.25 T22 Sets the duration of the Reset-Request timer (the number of
one-second ticks the MAX waits before retransmitting a
Reset-Request packet).
X.25 R22 The number of times the MAX retransmits a Reset-Request packet
before clearing a call.
X.25 T23 The duration of the Clear-Request timer (the number of one-second
ticks the MAX waits before retransmitting a Clear-Request packet).
X.25 R23 The number of Clear-Request retransmits the MAX sends before
waiting indefinitely for a response.
