Planning for MMCH
The following are some of the tasks you perform in planning and administering 
MMCH.
Planning the system
This is a list of questions to help you use DEFINITY ECS for multimedia. 
How many MMCH users are you going to have? 
How many multimedia calls do you expect to have at any given time?
With the information above you can determine how many Voice Conditioner (VC) 
and Multimedia Interface (MMI) circuit packs you need. 
Will users need data collaboration capabilities? If so, you need to install the 
Expansion Service Module (ESM).
Which stations, hunt groups or vectors need early answer? 
Do you have ISDN-PRI trunks? It is possible to use separate DS1 trunks 
for data, but ISDN-PRI trunks are recommended.
