The following information should be deleted.
BCM 3.0 software introduced the concept of Full Double Density (FDD) and Partial Double
Density (PDD). On the default system, DS30 02 to 05 were defaulted to FDD, which provides 32
new ports for connecting digital telephones. To use the FDD feature, DSM16+, DSM32+ media
bay modules are configured to double density. DS30 06 and 07 default to PDD, but can be
configured to FDD.

Table 6, Analog engineering specifications, should be replaced with the table below:
Warning: Changing DS30 06 and 07 to FDD
Once you change DS30 06 and 07 to FDD, Companion telephones can no longer
be supported. This change cannot be reversed.
