DSM16/DSM 32 single density switch settings (new system)

The following table shows the switch settings for DSM modules deployed as single density on a new system running BCM 3.0 or later software.

Note: DSM modules deployed prior to BCM 3.0 are all single density and cannot be set to double density, but they can still be used on new systems. The DSM 16+ and DSM32+ modules can be set to either density.

*The extensions listed are based on a three-digit DN with a Start DN of 221. If your system has longer DNs or a different Start DN, enter the range in the blank column.

**If your system is configured with a 3/5 split, you cannot use DS30 7 for the DSM 16 module. You cannot configure the DSM32 module for DS30 6 because the second set of DNs cannot be accessed.

DSM16+ and DSM 32+ double density switch settings (new system)

The following table shows the switch settings for DSM-plus modules deployed as double density on a new system (BCM 3.0 or later software).

Note: DSM modules deployed prior to BCM 3.0 are all single density and cannot be set to double density, but they can still be used on new systems. The DSM 16+ and DSM32+ modules can be set to either density.
