Application information
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.
Figure 9.
Examples of protection stages for line cards
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 protect the module against long duration or very high
current mains disturbances (50/60Hz). It acts by safe circuit opening. Lightning surge and
mains disturbance surges are defined by standards like GR1089, FCC part 68, ITU-T K20.
