Description If the X.25 switching function is not used, and two Routers are directly connected
back to back via the X.25 protocol, one Router shall work in DTE mode, while the
other shall work in DCE mode. When two Routers are connected via the X.25 public
packet network, they shall generally work in DTE mode. If the X.25 switching
function is used, the Router shall generally work in DCE mode.
In practice, select the IETF format of datagram if there is no special requirement.
