What the AI looks for in Telephone Wires
- Line cord vs handset cord
- Wall-to-phone line cords use RJ11 (6P2C or 6P4C) plugs. Coiled handset cords use the smaller 4P4C (RJ9/RJ22) plug. The two plug sizes are physically different and are not interchangeable.
- Conductor count
- Use 6P4C (four-wire) cords for two-line phones. 6P2C cords are enough for single-line phones. A two-conductor cord cannot carry line 2.
- Wiring for data devices
- For DSL modems and fax machines, use a short cord with twisted pair or round cable where possible, and keep the cord short. Long flat untwisted cords pick up noise that slows down DSL and fax connections.
- Length
- Buy only the length you need, and do not daisy-chain cords with inline couplers. Every extra connection and every extra metre adds signal loss and noise.
Brands that matter
- Monoprice: Large, consistent range of RJ11 line cords and couplers.
- Cable Matters: Well-made RJ11 cords and extension cables.
- GE: Widely sold home phone cords, couplers and splitters.
- Philips: Basic phone cords and accessories for home use.
What to avoid
- Using an RJ11 phone cord where an Ethernet (RJ45) cable is needed.
- Long flat cords on DSL connections.
- Multiple inline couplers to reach a distant jack.
Questions
Will an Ethernet cable work as a phone cord?
An RJ11 plug can sit in an RJ45 port, but an RJ45 plug does not fit an RJ11 jack, so use a proper phone cord.
