Overview

The Monoprice 100941 is a 14-foot RJ12 reverse landline telephone cable that provides a simple, effective way to connect a telephone to a wall jack when the included cable is too short or needs replacing. Both ends terminate in RJ12 6P6C plugs with all six conductors populated, supporting standard single-line and multi-line voice connections. The reverse wiring — where the pin order is mirrored between the two connectors — is the conventional configuration that landline telephones expect for proper communication with the phone network.

The flat, silver-satin cable body is designed for easy routing: it lies flush against baseboards, slides under carpet edges, and bends around corners without the bulk of a round cable. At 14 feet, it hits a practical middle ground — long enough to reach across most rooms or around furniture, but without the excess coil that comes with longer runs. For home offices, kitchen phones, or any setup where the wall jack and the phone are a moderate distance apart, the 100941 gets the connection done cleanly and reliably.

Frequently Asked Questions

The primary difference is length — this cable is 14 feet compared to the 100943's 25 feet. Both use the same RJ12 6P6C reverse wiring, connectors, and flat silver-satin construction.
Reverse wiring means the pin sequence is mirrored from one connector to the other. This is the standard wiring configuration required by most landline telephones to communicate with the wall jack.
Yes, the RJ12 6P6C connector has six conductors, which can carry multiple voice lines — enough for a standard two-line telephone setup.
This cable is wired for voice applications. While it physically fits RJ12/RJ11 jacks, its reverse wiring is designed for telephone use, not data or DSL service.
