A Broadmore 1750 with OC-12c NIM can utilize Cell Buses A, C, D, and E and

of 622.080 Mbps.
For NIM redundancy, install OC-12c NIMs in slots A and B
If a single OC-12c NIM is used, it should be installed in slot B
To utilize the 1:N SAM protection feature, working SAMs are installed in
slots C to N and the protection SAM is installed in slot P
NOTE:
Configurations using more than four Structured DS3 SAMs
require a high-capacity 3-fan tray for cooling. (Contact factory for details.)
