To connect a modem to an analog telephone line that has an
RJ-11 telephone jack:

which prevents interference with TV and radio reception,
orient the circuitry end of the cable toward the notebook.
3. Plug the modem cable into the RJ-11 telephone jack (not the
RJ-45 network jack) on the notebook 3.
4. Plug the other end of the modem cable into an RJ-11
telephone jack (not into an RJ-45 network jack or a
PBX jack) 4.
Connecting a modem to an RJ-11 telephone wall jack (Telephone
