Note

The Model 1080ARC communicates in a closed data circuit with 

another Model 1080ARC 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 on page 34.

Point-to-Point Twisted Pair Connection

The 6-position RJ-11 and 8-position RJ-45 jack options for the Model 
1080ARC are prewired for a standard TELCO wiring environment.  Con-
nection of a 2-wire or 4-wire twisted pair circuit between two or more 
Model 1080ARCs requires a crossover cable as shown in Table 27, 
Table 28, Table 29, Table 30 and Figure 8.

Connection to ground is optional
Standard color codes yours may be different

The Model 1080ARC is not sensitive to polarity
