Chapter 8 Installing a media bay module (MBM) 131BCM200/400 4.0 Installation and Maintenance GuideDSM switch settingsThere are different types of DSMs:• DSM16/DSM16+ have one connector, which connects to 16 lines (telephones). Thesemodules require a full DS30 number each (single density) or half a bus (double density).• DSM32/DSM32+ have two connectors, each of which connects to 16 lines (telephones).These modules require two full, consecutive DS30 numbers (single density) or one full bus(double density).This section includes these charts:• “DSM16/DSM32 single-density switch settings (upgraded system)” on page 131• “DSM16+ and DSM 32+ double density switch settings (upgraded system)” on page 132• “DSM16/DSM 32 single density switch settings (new system)” on page 133• “DSM16+ and DSM 32+ double density switch settings (new system)” on page 133DSM16/DSM32 single-density switch settings (upgraded system)The following table shows the switch settings for DSM modules deployed as single density on asystem. For single-density modules, you set the first DS30 number on the DIP switches and thesystem assigns the next DS30 bus. Note in Table 43 how the DSM32 module spans two DS30 busnumbers and that there are only five possible DS30 settings for the DIP switches.Note: Switch settings not shown in this table will default to the North Americanprofile.Table 42 ASM8+ country select DIP switch settingsManual settings(pre-BCM 3.6 systems) Country profile Manual settings(BCM 3.6 and newer systems)1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8off off off off off off off off North America on off off off off off off offoff off off off off off off on United Kingdom on off off off off off off onNote: DSM modules deployed with 2.5 systems are all single density and cannot be set todouble density.
