Installing an expansion unit
Adding an expansion unit increases the capacity of your BCM50 system by providing a method of
adding a media bay module (MBM). Each MBM you add increases the number of public switched
telephone network (PSTN) trunks or extensions that you can connect to the BCM50 system.
The figure Overview of installing a expansion unit on page 93 shows the steps required to install
the expansion unit.
