Frequently Asked Questions

Q: What does an RJ11 ADSL micro filter splitter do?

A: An RJ11 ADSL micro filter splitter separates the high-frequency DSL/ADSL internet signal from the low-frequency voice signal (POTS) on your telephone line. This allows you to use your phone or fax machine and DSL modem simultaneously on the same line without interference, static, or signal degradation.

Q: Is this adapter compatible with my phone and modem?

A: Yes — this splitter is compatible with any standard RJ11 telephone line. It works with DSL/ADSL modems, corded and cordless telephones, and fax machines that use standard RJ11 (6P4C) connectors. No special configuration is needed; simply plug in and go.

Q: Do I need one filter per device or just one for the whole line?

A: This single inline splitter handles the signal separation at your wall outlet jack, splitting the line into a dedicated phone/fax port and a dedicated modem port. For most standard setups, one unit at the main connection point is sufficient.
