Table 65 Description on the user facility option
Option	Description
window-size	Carries out the window size negotiation when initiating calls
input-window-size	from the X.25 interface. Window size negotiation is a part of
output-window-size	flow control parameter negotiation. It needs two parameters:
	input window size and output window size. When the modulo
	is 8, the size is in the range 1 to 7; when the modulo is 128, it is
	in the range 1 to 127.

Description Use the x25 call-facilitycommand to set user options for an X.25 interface. After an option is set, all X.25 calls from the X.25 interface will carry the relevant information field in call packet.

Use the undo x25 call-facilitycommand to delete the set option.

By default, no facility is set.

The user facilities set via this command are available for all the calls originating from this X.25 interface. You can also use the optional parameter option of the x25 map command to set user facility option for the X.25 call originating from a specific address map. What’s more, the priority of user facility configured with the x25 map command is higher than that configured with the x25 call-facilitycommand.

Related command: x25 map, x25 modulo.
