Hello:
I have to install a ISDN wic1bu to my existing 2610. I am currently using this router with a T1 CSU/DSU connected to a 384k serial dedicated line to my provider for internet access. I want to be able to have redundancy when my primary 384k line fails. How can I configure my 2610 to switch to the isdn when the T1 line fails?
Thanks
Jorge
