4.3.2  TWISTED PAIR CONNECTION

The Model 1065RC operates over one or two twisted pair. In 

all

applications, the twisted pair wire must be 26 AWG or thicker, uncondi-
tioned, dry, metallic wire. Both shielded and unshielded wire yield
favorable results. Note: The Model 1065RC communicates in a
closed data circuit with another Model 1065RC or other compatible
modem. Dial-up analog circuits, such as those used with a standard
Hayes-type modem, are 

not acceptable. For further information about

acceptable wire grades, please refer to the diagrams in Appendix B.

Point-to-Point Twisted Pair Connection

The 6-position RJ-11 and 8-position RJ-45 jack options for the

Model 1065RC are prewired for a standard TELCO wiring environment.
Connection of a 4-wire twisted pair circuit between two or more Model
1065RCs requires a 

crossover cable as shown in the following dia-

grams.

4.3.3  Multipoint Twisted Pair Connection

The Model 1065RC supports multipoint applications using a star

topology. Maximum distance between the units will vary based upon
the number of drops, data rate, wire gauge, etc. Call Patton Technical
Support for specific distance estimates. Figures 11 and 12 show how
to wire the one-pair and two-pair cables properly for a Model 1065RC
star topology. Note that the ground connection is not needed.
