If the cables are longer than 10 meters, there is a good chance that they
may run in cable troughs along side of cables that may come in from the out
of doors.

Subject: Surge (immunity) requirement for equipment in telecommunication c
enters
Hi,
The EN 300 386 (EMC requirements for telecommunication network equipment)
require to perform a surge of 1.2/50 Tr/Th us, 0,5 kV to ports for indoor
signal lines (in telecommunication centers), when cables longer than 10 m
are connected !
Can some one explain my the rational of divided up to 10 m and more than 10
m, anyway all cable is in the building (indoors) ?
