1.	Indicate the modules you want to install	4. Assign an offset
2.	Note how many DS30 buses each module requires	number to each module

3. Choose the DS30 numbers to	5. Make a note of the DIP switch settings for the DS30/offset numbers
assign to the modules	DIP switch setting for offset

Example: Position your DSM 32 MBM (step 1), which requires two full DS30 buses (step 2), in DS30 2 and 3 (step 3). Moving across, note that the offset is 0 (step 4). Set the DIP switches on the MBM to match the DIP switch settings indicated for that offset (step 5).

Table 28 shows possible DS30 and offset configurations for each type of trunk MBM, and the corresponding switch settings. For FEM settings, refer to “FEM switch settings” on page 133.
