Description This parameter in-packets determines the maximum number of correctly received
packets before X.25 sends the acknowledgement information. As long as the
bandwidth allows, the greater the window size, the higher the transmission efficiency.
Out-packets determines the maximum number of data packets sent by X.25
before it receives the correct acknowledgment information. As long as the bandwidth
allows, the greater the window size, the higher the transmission efficiency.
Please consult users’ ISP about the sending and receiving window sizes. Unless
supported by the network, do not set these two parameters to different values.
