TDSL and interleaving (Fastpath)
As GameSource found out when creating a DSL tutorial, there is allegedly no possibility of subsequently activating the Fastpath option on its connection, although with Fastpath only the preceding error correction of the transmitted data packets is switched off with an ADSL standard connection.
Although this error correction does not affect the speed of the data transmission, it does create the high ping that is extremely important for online gamers. So far, the user could turn off this function from Telekom and thus activate the Fastpath, which is probably no longer the case. The reason given by a telecommunications employee was that usually several people use one connection and that this method is used to influence the performance of other users, which, however, cannot be the only reason.
