These ranges can be extended to 5,000 feet (1524 m) for 24 AWG wire and 4,000

feet (1219 m) for 26 AWG wire with the use of a Data Link Protector (DLP).  Refer to

In 2-wire installations, the CALLMASTER III can be connected to a TN2181 port

board.

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.

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

later) or DEFINITY G1 and G3 and to a System 85 (R2V2 or later) or DEFINITY G2.
