4X16 switch settings
The 4X16 module combines a CTM and a DSM 16. The CTM only requires four lines on the
DS30 bus. Therefore, it can be assigned any of the four offsets in a DS30 bus. The DSM module
then automatically assigns the next DS30 number and all the assigned DNs.
This module can be combined with three other CTMs or one CTM8 on the same DS30 bus.
Table 60 shows the switch settings for each DS30 bus, and the assigned lines and dialing numbers
(DNs) for each DS30 bus.

** 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 configure this module for DS30 6
since DS30 7 is not available for the second level.
