Not sure I understand - you mean like a serial leased 
line?

First you need an ISDN-BRI interface - something like the 
WIC-1B-S/T-V3 (Cisco 1-port ISDN BRI S/T WAN Interface 
Card). You may also need an external NT-1 for 
connectivity to the local telco's ISDN switch.

You don't mention whether you'll be dialing from a router 
or PC, so I'll direct you to:

http://cisco.com/en/US/tech/tk801/tk133/tech_configuration_examples_list.html

There's lots of scenarios there that will be of interest. 

Cheers,

Mark.
