Hi All, I am hoping that someone has had some experience the interface definitions covered in the ITU K series recommendations. My question is regarding the interface references given as T<sub>1 and T<sub>2 in Table 1 of K.41. This is referring to the telecommunications interface, but it is not clear if the surge should be applied in common mode to all of the connections or if the reference is to a table of connections for 2 and 4 wire interfaces. Thanks in advance. Regards, Dave Spencer Oresis Communications
