The clearest way that I have ever heard this explained is the following.
Only one side can initiate the call if only one is given the number. But
who can tear down the call? Both of them can. That is why it is necessary
to create a dialer list for the side that does not make the call.
Calling router
1. Dialer list
2. dialer-group
3. dialer map
Called router
1. Dialer list
2. dialer-group

Paul,
Hopefully you don't think there is any such thing as "the correct way of
doing" anything... ;-)
My prefered way of setting up one-way calling is to remove the phone number
but keep the map statement and keep the dialer list. The reason is that if
you remove the dialer list, that end of the connection will always timeout
after the connection has been up for idle-timeout seconds, even if data is
traversing. Using a dialer list makes that router keep reseting its idle
timer. But it still cannot make the call, because it has no number to call.
(The map statement ties the name to the connection.)
If you do go with no dialer list, I would recommend setting the idle-timeout
to the maximum. Then the calling router basically controls the connection
completely.

Hi Guys
I'm just going over a few things in the lab and have a question about only
one end of an isdn backup link making the call. What is the correct way of
doing it, 1) remove the dialer-list but leave the map statement and phone
number, 2)remove the dialer-list but leave the map statement with no phone
nubmer, or 3) remove the dialer-list and the map statement
Cheers
