With J179/J169 phones, JEM24 button module capacity depends on whether a single or multiple modules are attached to phones:
A single JEM24 module on a phone provides 72 buttons in 3 pages of 24. In this mode, single modules are equivalent to 3 modules for overall capacity.
Multiple JEM24 modules on a phone only provide 24 buttons each.
Capacities are regardless of whether the buttons are configured for use or not, and whether physical or logical (as in the case of BM12 or JEM24).
