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 33 shows the switch settings for each DS30 bus, and the resulting line assignments.
