DC1135 with two to four stub lines
(zero ohm resistance on the circuit unit not removed)
Regardless of whether the stub lines have devices connected or not, each beginning
(DC1135m) and end (T-T END) of the four stub lines always has its own D-Bus address.
This means that the multiple T-branch module always occupies eight D-Bus addresses.

The eight nodes for the beginning (DC1135m) and end (T-T END) of the stub line
have no counterparts in the logical structure and thus remain unlinked.
Example: DC1135 with four stub lines
