Tests TS 101-952

TS-101-952-1 is a technical specification written by ETSI experts.
It provides a set of test methods to verify the electrical characteristics of an xDSL filter deployed in Europe.
This standard applies for Central Office, as well as CPE, filters. It allows to make sure that the filter will function correctly without impacting the loop characteristics. These tests are complementary to TR-127 tes t s def ined by the Broadband Forum which allows to dynamically validate the filter in its DSL system, by insuring that POTS transients will not impact the DSL link.
