DSM switch settings

There are different types of DSMs:

•DSM16/DSM16+ have one connector, which connects to 16 lines (telephones). These modules require a full DS30 number each (single density) or half a bus (double density).

•DSM32/DSM32+ have two connectors, each of which connects to 16 lines (telephones). These modules require two full, consecutive DS30 numbers (single density) or one full bus (double density).

This section includes these charts:

•“DSM16/DSM32 single-density switch settings (upgraded system)” on page 130

•“DSM16+ and DSM 32+ double density switch settings (upgraded system)” on page 131

•“DSM16/DSM 32 single density switch settings (new system)” on page 132

•“DSM16+ and DSM 32+ double density switch settings (new system)” on page 132

DSM16/DSM32 single-density switch settings (upgraded system)

The following table shows the switch settings for DSM modules deployed as single density on a system. For single-density modules, you set the first DS30 number on the DIP switches and the system assigns the next DS30 bus. Note in Table 42 how the DSM32 module spans two DS30 bus numbers and that there are only five possible DS30 settings for the DIP switches.

Note: DSM modules deployed with 2.5 systems are all single density and cannot be set to double density. The DSM 16+ and DSM 32+ modules can be set to either density.
