Installation
Note:
• The total length of the cables from the communication server to the system phone must not be less
than 10 m.
Restrictions
The maximum length of a DSI-AD2 bus is further restricted by:
• the maximum power requirements of the connected system phones and their supplementary
equipment. In this context the SB-4+ and SB-8 DECT radio units are also considered as system
phones.
• the line resistance (depending on the line length and wire diameter)
