APPENDIX C
EIA/TIA TSB-40A COMPLIANCE
The Model 570-Rx/580-Rx series surge protectors have been
designed to conform to stringent EIA/TIA TSB-40 standards as required
for all Category-5 connecting hardware. These standards specify the
capacitance and near end cross-talk (N.E.X.T) to insure proper
operation of ALL connected equipment. Specific test results are shown
in the tables on the following pages*.

TYPICAL NEAR-END CROSSTALK MEASUREMENT
*Note: All test results are for the Model 570-Rx/580-Rx
alone, not including
any external patch cables that are connected to the unit.
