One of the top priorities for the location engineering is the ability for later modification. Due to this general design concept, most of the locations enable the later installation of additional cabling and sockets. The wall cable duct is applied for cabling and socket installation along the walls. The duct ideally fulfils two functions in one: The cable housing and the receptacle housing. The wall cable duct is typically used for amplifier rooms, control rooms, shielded rooms, Jacky rooms.

The ground plane CP (connection point) is applied for modular raised floor with ground plane. The CP is a metal box which can house both the receptacles and the connectors. The cover plate is made of a solid galvanized steel plate with openings for the cabling. Receptacles can be implemented at the box bottom and the two side plates. For easier working on the plates, they can be easily dismantled.
