**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 DS30 split, you cannot use DS30 7 for the DSM 16 module. You cannot
configure the DSM 32 module for DS30 6 because the second set of DNs cannot be accessed.
Note: DSM modules deployed with BCM 2.5 systems are all single density and cannot be
set to double density. The DSM 16+ and DSM32+ modules can be set to either density.
