Power Requirements
The CALLMASTER voice terminals receive power from the system and do not require any exter-
nal power supply. However, adjunct equipment connected to the CALLMASTER II or III needs its
own power supply.
Switch Administration
The 602 CALLMASTER and CALLMASTER II and III can be used with DEFINITY G1, G2, G3,
System 75 (R1V3) and System 85 (R2V2 through R2V4). The 602 CALLMASTER can be
administered as itself. The CALLMASTER II and the CALLMASTER III must then be aliased as
a 602 CALLMASTER.

The following button diagrams of the 602 CALLMASTER and CALLMASTER II and III voice ter-
minals will help you administer both of these voice terminals connected to a System 75 (R1V3 or
