Karl-Heinz , if your unit attaches directly (in the US) to the phone system, via a "U" interface, you will need to apply surge tests. - this is also applicable in canada.
If you have a "S/T" interface then you will be behind a network terminator (ie NT1 or CSU/DSU) and do not need to do surge testing. Note: if you are sitting behind a NT1 then the FCC68 rules are not in effect as you are not attaching directly to the telephone line. The only tests I can think of that would be applicable would be through gain and the enviromental drop test. However, in Canada you can attach "S/T" directly to the telephone line and would need to do applicable IC tests.
