APPENDIX B

PATTON MODEL 2715

CABLE RECOMMENDATIONS

The Patton Model 2715 has been performance tested by Patton technicians using twisted-pair cable with the following characteristics:

Wire Gauge	Capacitance	Resistance
19 AWG	83nf/mi or 15.72 pf/ft.	.0163 Ohms/ft.
22 AWG	83nf/mi or 15.72 pf/ft.	.0326 Ohms/ft.
24 AWG	83nf/mi or 15.72 pf/ft.	.05165 Ohms/ft.

To gain optimum performance from the Model 2715 , please keep the following guidelines in mind:

•Always use twisted pair wire—this is not an option.

•Use twisted pair wire with a capacitance of 20pf/ft or less.

•Avoid twisted pair wire thinner than 26 AWG (i.e. avoid AWG numbers higher than 26)

•Use of twisted pair with a resistance greater than the above specifications may cause a reduction in maximum distance obtain- able. Functionality should not be affected.

•Many environmental factors can affect the maximum distance obtainable at a particular site. Use the above data rate/distance table as a general guideline only.
