Choosing the assigned order for MBMs
Assign the MBMs and DS30 buses in the order shown in Figure 69 on page 117 .
Station MBMs are assigned starting with DS30 2. This allows telephones to start numbering from
the system Start DN (the default is 221).
Trunk MBMs are assigned starting at DS30 7 in a system with a 2/6 DS30 split, and at DS30 6 in a
system with a 3/5 split. The exception to this are the 4x16, 8x16, and the DDIM, which require two
DS30 buses that must be set to a DS30 that has the next bus open.
Figure 69 Assigning single-density MBMs to the DS30 bus hierarchy
Trunk MBMs are assigned
starting with the last
available MBM DS30 bus
(DS30 6 or 7, depending on
the bus split in effect).
Exception: A 4x16, 8x16, or a
DDIM cannot be assigned to
the last DS30 bus.

3/5 bus split
* DS30 7 is not available to any MBM if your system has been
configured with a 3/5 bus split
MBMs that require two DS30 buses, such as the DSM32, 4x16, 8x16,
and DDIM must be assigned to DS30s higher than 6, to accommodate
all the resource requirements.
