Table 8 - Additional Electrical Characteristics
8.0 Zero Cross Current Turn Off
The ring access switch (SW8) is designed to turn off on the next zero current crossing after application of the
appropriate logic input control. This switch requires a current zero cross to turn off. Switch 8, once on, will remain in
the ON state (regardless of logic input) until a current zero cross. Therefore, to ensure proper operation of switch 8,
this switch should be connected, via proper impedance, to the ringing generator or some other ac source. Do not
attempt to switch pure DC with switch 8. The ringing test access switch, SW6, also has similar characteristics to
switch 8 and should also only be used to switch signals with zero current crossings.
For a detailed explanation of the operation of switches 6 and 8, please refer to the An Introduction to Le758X Series
of Line Card Access Switches application note.
