Thanks RCA. Amen, to the phone companies. We fight with them all the time and the customer is in the middle. However, we received new info after I posted this, they went down this morning and found out they had a CSU loop, which is in the T-1 Card. It is looping by itself. We just want to be sure it more than likely is a bad T-1 card before we suggest to them to purchase it. We don't believe in selling equipment to the customers unnecessarily.
