APPLICATION NOTE
In wireline applications, analog or digital, both central office and subscriber sides have to be protected.
This function is assumed by a combined series / parallel protection stage.

(typical values)
In such a stage, parallel function is assumed by one or several Trisil, and is used to protect against short
duration surge (lightning). During this kind of surges the Trisil limits the voltage across the device to be
protected at its break over value and then fires. The fuse assumes the series function, and is used to pro-
tect the module against long duration or very high current mains disturbances (50/60Hz). It acts by safe
circuits opening. Lightning surge and mains disturbance surges are defined by standards like GR1089,
FCC part 68, ITU-T K20.
