Caution:
Except for interfaces encapsulated with X.25 or LAPB, all physical interfaces can use
CQ.
You can apply CQ to a dialer interface successfully only when default queuing is
configured on its physical interfaces. The configuration, however cannot update to its
physical interfaces immediately if they have connections with their respective
connected devices. Instead, the configuration updates to the physical interfaces the
next time they set up connections.
