Karl, 

The following type of surge is applicable for BRI. FCC uses three types of 
classification for ISDN Bri equipment. 

For DE and DD type interface 
Line Surge type A (metallic and Longitudinal)  
Line Surge type B (metallic and Longitudinal) 
Power line surge if applicable 


For XD interface( Behind NT1) 
Power line surge if applicable
