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 137
•
“DSM16+ and DSM 32+ double density switch settings (upgraded system)” on page 138
•
“DSM16/DSM 32 single density switch settings (new system)” on page 139

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
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.
