This behaviour is only true with MPPP, I think. The trouble with this =
is, that currently only a client sided dynamic MPPP is useful, but you =
can't regulate the behaviour of MPPP on the PM3-side (that means only =
that I've not found it until now, HINTS WOULD BE WELCOMED! :-), and I =
think that the ComOS is trying to use MPPP always to the max of allowed =
connections, not dynamic, so it steadyly dials out and tries to connect, =
giving the router on the other side slim to none chance to make his =
dialback on the oder line.... On the other hand, we've to allow two =
connections in the location, as I understand this will be used for =
authentication, overriding RADIUS (even if the connections are logged by =
RADIUS accounting....)
