Overview

The Monoprice 100938 is a 7-foot landline telephone cable terminated with RJ12 (6P6C) connectors on both ends. Unlike the more common RJ11 (6P4C) cables that wire only four of the six available conductors, this cable connects all six pins in a straight-through configuration, making it appropriate for data line applications that require the full complement of conductors. The straight wiring means each pin maps directly to the same pin on the opposite end — the correct configuration for connecting devices to wall jacks or line-side equipment.

At seven feet, the cable provides enough length for typical office and home desk setups without leaving excessive slack. Monoprice has built a reputation for delivering reliable connectivity products at budget-friendly prices, and this cable follows that pattern. It is a practical, no-frills solution for anyone who needs a properly wired RJ12 data cable at a reasonable length and cost.

Frequently Asked Questions

It uses RJ12 (6P6C) connectors, which have six positions and six conductors — all six pins are wired, unlike the four-conductor RJ11 used by most voice-only phone lines.
While physically compatible with standard telephone jacks, this cable is straight-wired and designed for data line use. Most voice telephone applications also work fine with straight-wired cables.
Straight-wired means pin 1 on one end connects to pin 1 on the other end, and so on for all six conductors. This is in contrast to reversed or crossover wiring used in some handset cords.
Seven feet provides adequate reach from a wall jack to a nearby desk or device. For longer runs, a different length cable would be needed.
