APPENDIX C
EIA/TIA TSB-40A COMPLIANCE
The Model 57x/58x 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 capaci-
tance 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*.
