Restrictions
The maximum length of an DSI-AD2 bus is further restricted by:
• the maximum power requirements of the connected system phones and their sup-
plementary 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)
