Fig. 42 DSI-AD2 bus
Notes
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 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)
