About Partial Double Density mode

A B2 extension is a spare extension that exists on buses 6 and 7 only if you have Partial Double Density mode enabled. All other buses have only B1 extensions, no matter what mode the Business Communications Manager is in.

Partial Double Density mode is the default setting for Business Communications Manager.

Partial Double Density mode allows compatibility with Companion base stations.

You can manually change CDNs from B1s to B2s by entering a B2 CDN in the skillset properties. If the Business Communications Manager is changed to Full Double Density mode, the system will change the B2 CDNs to B1s.
