Re: ISDN 2b+1d support on incoming connection.

Can you explain this a little better? At the most, you can support 4 64k calls simultaneously. That doesn't take into account how many remote sites you have or the possibility as to how many might try to dial in at the same time.

If your question is if theoretically tou can configure 15 interfaces for the remote sites in the 1721 the answer is yes.

Use dialer profiles and put the BRI's in the same pool

Interface BRI0/0

encap ppp

dialer pool-member 4 priority 255
