Internal csu switching to external csu 3740

I am required to swap my interal csu/dsu for an external due to telco monitoring the external csu/dsu. When swapped I do not appear to be getting full v.35 connectivity to the csu/dsu. My encapsulation and lmi type have not changed. All options are all set on the serial interface. Does anyone know of any changes that might have to take place. I tried to look at the controller but the t-1 setting are the same. It could also be a telco issue but I cannot confirm that yet.

External CSU/DSU needed to have clock source internal command to provide clocking like the telco would normally.Refer URL
