For a T1 the phone company would expect to see their Network Interface 
Unit (NIU) which can be looped with a special repeating code. Using a 
different repeating code they would expect to be able to loop up a 
Circuit Service Unit (CSU). The NIU belongs to the phone company. The 
NIU would belong to the customer.

A CSU is not needed for voice TDM services and so does not usually exist.

I do not believe the Digium T1 cards have built in the CSU functionality 
and so the phone company will not be able to loop it. When I have talked 
with the phone company I just tell them that there is not a CSU.

If CSU functionality is required, it would require a change to the driver.
