| Abstract: | The original DSL interface protection circuit which meets the requirements of ITU-T k.20/21 could not satisfy the AC Power Fault test requirements in GR-1089-CORE. Therefore, a new method using telecommunication FUSE and GDT of overcurrent and overvohage protection for DSL interface circuit is proposed. It is shown that the new method is feasible and effective ＋after AC Power Fault tests. |
