4.1.1 Two-Wire Cable Connection Via RJ-45
A. The RJ-45 jack on a Model 1065 Series Short Range Modem is
prewired for a standard TELCO wiring environment. To be sure you
have the right wiring, use the table below as a guide.

4.2 FOUR-WIRE INSTALLATION
When communicating over a two twisted pair circuit, the Model
1065 can operate full or half duplex, point-to-point or multipoint. In two
pair point-to-point applications, you will need a
pair of Model 1065s for
each circuit—one at each end of the two pair cable. In two pair multi-
point applications you will need three or more Model 1065 units. These
can be connected using a star topology, although a daisy chain topolo-
gy is usually used.
