**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 channel 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.
****If you need more DNs for Companion sets, use the range that starts at 597 (ISDN or DECT) and change the
DN type to NA Portable.
*****If you system is set to Full Double Density (FDD), Companion telephones are not supported.
