APPENDIX B
CABLE RECOMMENDATIONS
The Patton NetLink T1™ Series has been performance tested by Patton
technicians using twisted-pair cable with the following characteristics:
To gain optimum performance from the Model 2710 Series, 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 speciÞca-
tions may cause a reduction in maximum distance obtainable. Func-
tionality should not be affected.
• Many environmental factors can affect the maximum distance obtain-
able at a particular site.
Wire Gauge Capacitance Resistance
