| The Figure
shows additional commands that you can configure for X.25
connections. An X.121 address is assigned to interface serial
0. This example shows how to specify X.25 windows and packets sizes.
The input and output packet and window sizes and the maximum number
of VCs for any protocol are also defined. See Table
for descriptions of the preceding example.
The typical default packet size
provided worldwide by PDNs is 128 bytes. In the United States and
Europe, default packet sizes of 1024 are common. Other countries can
also provide higher packet sizes. The Layer 3 default maximum packet
size is subject to the limit that lower layers are able to support.
