router, and does not originate from the local subnet (LAN segment to which the router is
attached via the Ethernet interface). However, this means that if you are routing traffic from
the local subnet across a VPN tunnel, you would have to set up two Eroutes: one to match the
local subnet address, and one to match the XOT source address, such as the address of the
PPP interface associated with to the wireless network. If set to Ethernet, the router uses the
IP address of the Ethernet port instead of that of the PPP interface, so that you need only set
up on Eroute.
6. Configure X.25 parameters:
Don't switch facilities
If this parameter is set to Off, the packet size and window size are only switched if they need
to, such as if they specify a value different from what is currently being negotiated. If this
parameter is set to On, the facilities are not switched.
Don't strip facilities
When set to On, this parameter stops the X.25 switch from stripping packet size and window
size facilities as it switches an X.25 call. When set to Off, the X.25 switch strips facilities if the
requested facilities match the defined defaults for that interface.
L2 Deactivation Clear Cause
When one side of a switch call fails because layer 2 drops, the other side is usually cleared with
a clear cause 9,out of order. This parameter allows you to set this code to any value.
X25 Version: 84 88
Allows you to switch between X.25 version 88, and X.25 version 84, in which clear causes are
always 0 when issued if the router is the DTE.
Interpret no facilities on Call Accept as P7W2
When this parameter is set to On, the X.25 switch interprets any call accept packets that do
not include the window size (W) or packet size (P) as if the call accept has P7W2, such as a
packet size of 128 bytes and a windows size of 2.
