Distributed Office implementation
The Distributed Office solution provides a set of standard hardware configurations or constructs 
and set of provisioning profiles. A construct is chosen that best satisfies the hardware 
requirements for one ore more locations. A provisioning profile, consisting of a set of files 
containing provisioning data, is selected and loaded onto the hardware platform.
Selecting a construct 
When you use the Avaya Solution Designer to create a configuration template for a group of 
branch locations, the choice of a construct is the most important parameter. The choice of 
construct determines the number of lines and trunks of each type. The goal is to choose the 
smallest construct that accommodates the maximum requirements assuming growth.
The first consideration when choosing a construct is the Distributed Office model, i40 or i120. A 
construct that uses the i120 model provides a larger number of lines and trunks than the i40, as 
well as higher capacities for several other parameters such as the number of voice mail boxes, 
the number of DSPs, and the busy hour call completion rate.
