MBM combinations
This section describes some combinations of trunk and station MBMs to demonstrate how to fit
the MBMs into the DS30 resources. These configurations are meant to help demonstrate how your
system can be configured using the information in this guide and do not necessarily reflect real-life
configurations.
Combining CTM/GATMs, 8x16s, and 4x16s
The 4x16 combination MBM is a combination of a CTM4 and a DSM16 (GATM4 and DSM16 for
G4x16). A maximum of four CTM4/GATM4s can fit into a DS30 bus when each is given a
different offset. Therefore, you can combine a maximum of three CTM4/GATM4s with a 4x16
MBM. This configuration would occupy two full DS30 buses.
The 8x16 combination MBM is a combination of a GATM8 and a DSM16. A maximum of two
CTM8/GATM8s can share a DS30 bus when each is given a different offset. Therefore, you can
combine either a maximum of two CTM4/GATM4s or one CTM8/GATM8s with a 8x16 MBM.
This configuration would occupy two full DS30 buses.
