This function is assumed by a combined series / parallel protection stage Figure 10. Examples of protection stages for line cards Line Ex. Analog line card Protection stage Line Protection stage Ring relay Ex. ADSL line card or terminal 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 circuits opening. Lightning surge and mains disturbance surges are defined by standards like GR1089, TIA/EIA IS-968, ITU-T K20. 6/13 Doc ID 9699 Rev 5 SMP100MC Application information Figure 11.
