I don't think you would have any problems defining the entire E1 (30 b
chans) in both config files.  Provided you do not disable
resetinterval, and your telco only signals the correct number of b
chans as "up", you should be fine.

With that configuration, one phone call to the telco "Yes, can you
please turn up X more channels on my E1" should result in no user
intervention on your side to utilize the new b chans as they are
turned up.

Thanks,
