Planning and installation

Connecting terminal units
a) Terminal units that are not in the vicinity of the telephone system have to be
plugged into the telephone jacks or wall outlets that have been installed before.
b) Western jacks for the first extensions:
Please use one particular jack exclusively for each terminal device in the centre
of the jack array. Pinning of the jacks is in compliance with international
Standards, defining the two central wires as a/b. Please consult your telephone
dealer about such cables.
Please keep in mind that due to alternative connection options (screwing terminal or
western jack) unintentional parallel connection of terminal units cannot be ruled
out. Make sure that you only use one of these alternative connections methods
per terminal unit.
