8.9.4 Interface to “public telecommunication system”

The equipment is not constructed for electrical connection directly to a
"public telecommunication system". None of the signals shall be
connected directly from the unit to a "public telecommunication
system" leaving the building without using some kind of interface in
between such as a telecom terminal, switch or similar unit. Such kind
of buffer is required to achieve a protective electrical barrier between
the "public telecommunication system" and the unit. This electrical
barrier is required to achieve protection against lightening or faults in
nearby electrical installations.
