Changing configurations
Here are some points to consider when changing modules in existing or in new Business
Communications Manager systems:
• Trunk and analog station modules cannot share a DS30 channel.
• Modules that require more than one DS30 channel automatically assign the next channel in
chronological order.
Therefore, if an existing, installed module uses either of the required DS30 channels, remove
the installed module. You must then assign the DIP switches for both modules so there is no
conflict between them or with any other installed module.
• The goal is to have a balanced mix of trunk and station modules.
• Write the DIP switch settings for each module in a place that is handy to reference when you
decide to change or add modules.
• If you update your Norstar system to Business Communications Manager, your station
amphenol connectors can be connected into the media bay modules without adjustment. Trunk
connectors must be converted to RJ11 (CTM) or RJ45 (BRI) connectors.
However, if you use the FEM module to connect your Norstar modules to the Business
Communications Manager hardware, the station wiring needs to be adjusted. Refer to
“FEM
wiring” on page 182 .
