An ADSL POTS splitter includes low pass filter. Advantages: simplification of manufacturing and packaging methods. Further, the domain profiles may be XML files. An \u201cSSL capacity\u201d value for each server is calculated which represents the capability of that server to process SSL connections. The invention applies in particular to the fabrication of multi-channel transistors, of the FinFET, suspended-channel, ITS or GAA type.
