Connecting the fiber cables
Follow these steps to connect your Norstar expansion modules to a FEM module installed into a
BCM1000.
1 Ensure the BCM1000 is properly powered and rebooted.
2 Connect the fiber cables from the Norstar expansion modules to the jacks on the FEM module.
a Connect the Norstar Line Modules to the FEM beginning at fiber port 1.
b Connect Norstar Extension Modules to the FEM beginning at fiber port 6.
3 Change the DN records in the Unified Manager or change the set wiring, as required, to match
your system.
Table 33 compares the designated extension numbers on the Norstar and on the Business
Communications Manager.
Note: Which DIP switch settings you chose will determine which FEM ports are
available. Refer to “FEM switch settings” on page 150 .
Warning: When you connect a Norstar station module to an FEM, the extension numbers
of the telephones connected to the station module change. To keep the same extension
numbers, change the DNs of the telephones or change the telephone wiring to correspond
with the required DNs.
Note: If you connect a Norstar station module amphenol cable directly to a DSM, you do
not have to change any settings to maintain the DN assignments.
