I'm surprised TelMex hasn't gone to ADSL2+ which uses double bundles of copper wire.Done yesterday. Got 49 down and 48 up. that is at the lower level.
You cannot connect the fiber optic coming from the street directly to the copper telephone wire in the house. Consequently you have to connect your house phone , if you want one, directly to the modem. There are regular telephone jacks on the modem for that. You can string fiber optic inside the house if you have conduit to the location you want to place the telephone, or hang it on the wall !! But you cannot use the existing copper phone wire with the fiber optic.sounds confusing
