Do not waste time and money trying to connect two ADSL modems to the same CANTV line. Instead, invest in a good router or a mesh Wi-Fi system to solve connectivity and coverage problems. If you truly need two separate internet connections, you must contract two independent telephone lines from CANTV/Movistar.
Short answer: No, not in the way most users expect or need. Connecting two standard ADSL modems simultaneously to the same active CANTV telephone line is technically unfeasible for achieving two independent internet connections.
