An ADSL cable is the phone line cord that links your wall jack to a DSL/ADSL modem so the internet signal travels over your home’s telephone line. On this page, those cords are typically labeled “RJ11” or “6P4C,” and you’ll see descriptions like “DSL/Modem/Fax.”

• Purpose: Carry DSL/ADSL signal from the wall jack to the modem.
• Connector: RJ11 (smaller plug than Ethernet).
• Pair with Ethernet: Use an Ethernet (RJ45) cable from the modem or router to your computer, TV, or console.
• Tip: Pick a length that reaches comfortably, and if your provider supplied a DSL filter, connect it as directed.

They’re used in different parts of your setup. A DSL cord (often marked RJ11/6P4C) goes from the wall phone jack to your DSL/ADSL modem. An Ethernet cable (RJ45) connects the modem or router to devices like PCs, TVs, and game consoles.

• DSL cords: Smaller RJ11 connector; carries internet over the phone line.
• Ethernet cables: Larger RJ45 plug; available in Cat5e, Cat6, Cat6A, Cat8 for network speeds.
• Where to use: Wall jack → modem (DSL cord), then modem/router → devices (Ethernet).
• Quick ID: RJ11 is narrower; RJ45 is wider with 8 pins.

Many homes still rely on DSL/ADSL service where phone-line internet is available. If your provider supplied a DSL or ADSL modem, you’ll typically connect an RJ11 phone cord from the wall jack to the modem, then use Ethernet (RJ45) cables between the modem/router and your devices.

• Typical setup: Wall jack → modem (RJ11), modem → router (Ethernet), router → devices (Ethernet or Wi‑Fi).
• Availability: Service and speeds vary by provider and location—check with your ISP.
• Shopping tip: Look for “RJ11 6P4C” for phone cords and “Cat5e/Cat6” for Ethernet.
• Convenience: You can order cables online and choose pickup or delivery options.

In most setups, a “DSL cable” is simply a standard telephone cord (RJ11) used to connect the wall jack to a DSL/ADSL modem. You’ll see RJ11 6P4C cords on this page marketed for “DSL/Modem/Fax,” which is the same connector style used by phones.

• Same connector: RJ11 for both DSL and regular phone handsets.
• Labeling: Cords may be marketed as “DSL” to indicate modem use.
• Build differences: Some cords offer shielding or longer lengths for cleaner runs.
• Important: Don’t confuse RJ11 phone cords with RJ45 Ethernet cables—they serve different roles.

Use two cable types: a phone cord for the DSL signal and Ethernet for your network.

• Wall jack to modem: RJ11 6P4C telephone/DSL cord.
• Modem to router: Ethernet cable with RJ45 (Cat5e or Cat6 are common).
• Router to devices: Additional Ethernet cables as needed.
• Choose length: Measure your runs and avoid tight pulls or trip hazards.
• Features: Snagless boots help prevent latch damage; flat cables fit under rugs or in tight spaces.
• Environment: For exterior runs of Ethernet, consider weather‑resistant options available here.
