ISDN Frustrations

Good Morning,
 
Have some big time ISDN frustrations.
 
If spoke is to call hub, but the task doesn't explicitly tell me that
the hub is to be able to call the spoke and there isn't any callback
stuff needed to complete the task then do I configure dialer map
statements on the hub for the spoke?
 
I know I can configure a dialer map on the hub without the LDN to make
it so the hub cannot call the spoke or as we know we can slap the LDN on
there and give the hub that option.
 
What would you do in the lab if the requirement was for the spoke to be
able to call the hub, but the hub wasn't supposed to call the spoke?
Would you configure ANY kind of dialer map on the hub? I am afraid that
if I configure the hub with dialer map statements (over configuring) I
might give the proctor the perception that I don't know how to configure
ISDN optimally for the requirement - lets assume the proctor wont help
to clarify on this point - its all up to me.
 
Also, for bringing up the second B channel.. I have seen so many
different examples of configuring ppp multilink on CCO and IPEXPERTS. In
the lab would you configure two dialer maps on the spoke or would you
use just one? I unfortunately am having problems at home with my ISDN
simulator and can not give myself a definitive answer on whether I can
even bring up the second B if I have only 1 dialer map statement in the
spoke.
 
Sorry for the long post.
 
Scott
