4.1.5.2 Connecting telephone lines
Connect the telephone lines as shown in figure 4.5.
Caution
A connection to a telephone network must
always be made via a telephone coupler that
provides adequate isolation between the
telephone network (PBX) and the Plena system.
The telephone coupler must also meet all
relevant requirements for this type of
communication equipment as imposed by law
and/or responsible telecommunication
organizations in the country of use. Never try to
make a direct connection between the telephone
network and the mixer amplifier.
