Attaching Multiple Expansion Modules

Multiple modules (up to 3 total modules) can be piggy-backed to an IP phone providing an additional 108 softkeys with
M670is and an additional 180 softkeys with M675is. You connect the additional modules to the right side of an existing
module. The following figure illustrates the addition of multiple M675i modules on the 6755i IP Phone.
For more information about setting the softkeys, see the Aastra Model 6755i IP Phone User Guide.
