Expansion Modules

Pay-only-as-you-grow expansion uses snap-in modules to bring the total to 15 lines and 41 extensions or 19 lines and 9 extensions--depending on your needs.

With the addition of a 5 Slot Carrier or 2 Slot Carrier, the Partner ACS has modules that allow you to expand the system beyond it's initial 5 lines and 9 extensions. The 308EC Module gives you the ability to add an additional 3 lines and 8 Extensions.
