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.

Pros & Cons

👍 Pros

  • Full 6P6C (RJ12) wiring with all six conductors supports data line applications
  • Seven-foot length provides practical reach for desk-to-jack connections
  • Straight-wired configuration is correct for line connections between wall jacks and devices
  • Monoprice pricing makes it an economical replacement or spare cable

👎 Cons

  • Seven-foot length may be too short for rooms where the jack is far from the equipment
  • RJ12 connectors are physically larger than RJ11 and may not seat properly in some RJ11-only jacks
  • Limited to a single length option — no flexibility if you need slightly more or less cable
  • Basic cable with no shielding, which may be a concern in electrically noisy environments

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.
