DSM switch settings

The DSMs support 16 internal lines. The DSM16 and DSM32 are legacy modules only support single density on a bus. Therefore, you can only install one DSM16 per DS30 bus, and one DSM32 for two DS30 bus blocks. For this configuration, the offset is always 0.

Warning: Ensure that switches 1, 2, and 3 are always set to On, otherwise your module will not function.

The DSM16+ and DSM32+ were introduced in conjunction with BCM 3.0 software. These modules can be configured in either single density or double density mode. In double density mode, you can install two DSM16+ modules (offset 0 and 1) or one DS32+ (offset is still 0) on one DS30, providing 32 DN lines per bus.

Table 22 shows the switch settings for each DS30 bus, and the dialing numbers (DNs) assigned to each bus for systems that have been upgraded from BCM 2.5 software to BCM 3.0 or newer software. Note that Companion sets can only be assigned on DS30 06 and 07, and the handsets have a different set of default DNs than the digital sets.

Table 23 shows the switch settings for each DS30 bus and the DNs assigned to each bus for systems that were new with BCM 3.0 or newer software.

On these two tables, note that the modules only use the top 16 DNs for each DS30 bus occupied. In a single-density configuration, it does not matter if the bus is FDD or PDD, only the top 16 lines can be accessed.
