Summary:
|
Recommendation ITU-T K.146 deals with the management of electromagnetic interference produced by electrified railways traction systems on telecommunication systems in DSL frequency band.
This Recommendation defines only a procedure to evaluate the acceptability of an electromagnetic DSL interference and gives:
- the criteria defining the Quality of Service that has to be reached;
- the limits of the commercial ADSL offer guaranteed by an Internet Service Provider in conjunction with a telecom operator if necessary in the vicinity of potential disturbing railway;
- the installation conditions of electrified traction and telecommunication systems under which the recommendation applies.
This Recommendation helps to establish a contract between Internet Service Providers in conjunction with telecommunication operators if necessary and railway operators in order to clearly share responsibilities, and, as a consequence, if necessary, the relevant expenses for mitigation measures.
