Changing configurations
Here are some points to consider when changing modules in existing or new BCM systems:
• Trunk and analog station MBMs cannot share a DS30 bus.
• MBMs that require more than one DS30 bus automatically assign the next bus in
chronological order. Therefore, if an existing installed MBM uses either of the required DS30
buses, remove the installed MBM. You must then assign the DIP switches for both MBMs so
there is no conflict between them or with any other installed MBM.
