Notes:
1. A call process is equivalent to one party in a call. For example, in a call where two parties are 
talking and a third is on hold (consultation call), three call processes are involved; an 
eight-party conference consists of eight call processes.
2. The following telephone keys (on SUPERSET 430, SUPERSET 4025, SUPERSET 4125, and 
SUPERSET 4150 telephones) are considered Mode Processes: SUPERKEY, Messaging 
softkey, Phonebook softkey, and Account Code softkey.
