There is no way to prioritize dialer
maps that will cause existing connections
to be torn down. The best that I can
suggest is you try the command ,
which will cause the fast-idle timer to be
used instead of the idle-timer in the
event that all links are used and we need
to dial out to a new site. If the existing links
still have interesting data, you may not
see a disconnect right away. You could set the
fast-idle to a low value (like 5), but
beware that this may cause more than just
2 links to drop.
