DDIM switch settings

The DDIM combines a DTM and a data module. The switch setting you choose determines the
DS30 bus assigned to the DTM portion of the DDIM. The data module is automatically assigned
the next DS30 bus number.
The DS30 bus you assign to the DDIM determines the line numbers of the T1 line connected to the
DDIM. Table 34
