Figure 13 Assigning double density modules to the DS30 bus hierarchy
Setting module DIP switches for double density
Doubling the available telephone lines also requires additional DN records to accommodate the additional
telephones. The following charts show the DIP switch settings for single and double-density. Note that the ASM8s
do not have special double-density/single-density settings, whereas DSM16 and DSM32 modules must be set to
one mode or the other.
Note that the second set of 16 lines are not consecutively numbered from the first set. This was done to
accommodate existing installations.
ASM 8 switch settings
In a single density configuration, such as for DS30 06 or 07 when they are set to the default PDD, only offset 1
and 2 are available to ASM8s. In a double-density configuration, you can install four ASM8s per DS30 bus. Table
1 shows the switch settings for each DS30 bus and the dialing numbers (DNs) assigned to each DS30.
Partial density
Systems configured with Partial double density (PDD), allow
Companion telephones on DS30 06 and 07 (if the system is
set to a 2/6 split). In this configuration, DS30 06 and 07 only
allow single-density modules. DS30 02 to 05 are set to allow
double density modules.
Double density
Systems configured with Full double density (FDD), do not
allow Companion telephones. All DS30s are set to allow
double density modules.
3/5 channel split
If your system is set to a 3/5 split, DS30 07 is not available to
any media bay modules.
