Check the scopes. EN 300 386-2 is for the Central Office side of the
demarkation point. It is for equipment which IS the network. That leaves
EN55024 for equipment that is on the customer premise side of the
demarkation point or is ITE that doesn't connect to the network. EN55024 is
for telco terminal equipment.
If your equipment goes in both places, test the extra non-overlap parts of
the two standards and declare conformity to both.
As for the generics, product family standards superceed the generics. For
ITE that go in heavy industrial environments it may be appropriate to
increase the levels of specific tests of EN55024 to the levels of EN50082-2
in order to prevent customer disatisfaction with your product, but you can
CE mark your ITE for any environment with EN55024 alone. After all
conflicting standards are withdrawn for EN55024 in 2001, it would be
inappropriate to CE mark an ITE product based on test data to EN50082-2
alone. EN55024 has specific test configurations and among other things,
extra surge tests to cover the special product family needs of ITE.

Thanks to all of you for your info - but I'm still a bit confused Is
the applicable standard for telecommunications terminal equipment EN
55024 or is it EN 300 386-2 ? It's my understanding that both standards
cite EN 61000-4 sections but that there is a difference- EN 61000-4-8 is
called out in EN 55024 but not in
EN 300 386-2. Which is the applicable standard?
