BCM200/400 4.0 Installation and Maintenance Guide
Combining CTMs/GATMs and 4x16s
The 4x16 combination MBM is a combination of a CTM4 and a DSM16. A maximum of four
CTM4s/GATM4s can fit into a DS30 bus when each is given a different offset. Therefore, you can
combine a maximum of three CTM4s/GATM4s with a 4x16 MBM. This configuration would
occupy two full DS30 buses.
You can install a maximum of three of the above combinations in a BCM system with an
expansion unit added to it. Table 52 demonstrates this configuration of CTMs and 4x16 MBMs,
including the switch settings for each MBM.
Fully-loaded setup
This section describes a system containing one DSM 32/32+, one DSM 16/16+, two ASM 8s, and
two DTMs. This configuration uses all the DS30 buses, with the exception of two offsets.
