Is it possible to use 2 different usb modems, in 2 different rooms ,with 2 different phone points, using the same adsl phone line without conflict?? Thanks..
I would say no.
ADSL separates the phone line in two different bandwidth’s, the phone can use one while the other half can be occupied with a DSL connection.
It’s possible to use the Phone’s bandwidth with a dial-up modem, but effective use of both halves with ADSL modems is’nt possible
