Vszerda RJ45 to RJ11 Telephone Adapter Kit (2 Pack)

SKU CH-ESJ4-P0396

Two 6-inch RJ45-to-RJ11 cables and two RJ45 couplers connect landline devices over existing Ethernet wiring

  • Connect landline devices through existing Ethernet wiring
  • Gold-plated contacts ensure reliable voice signal transmission
  • Pure copper 28 AWG conductors maintain clear audio quality
  • Shielded RJ45 couplers support Cat5e to Cat7 cables
  • 6-inch cables with 11-pin wiring adapt RJ11 to RJ45

Adapter Kit for Ethernet-Wired Homes

This Vszerda kit connects a landline telephone, fax or DSL modem through existing Ethernet wiring when no telephone wall jack is present. It includes two RJ45-to-RJ11 cables and two RJ45 female-to-female couplers so the two ends can be linked with a standard Ethernet cable. The adapters are intended for homes that only have Ethernet infrastructure installed.

Pin-Mapped Cables and Couplers for Voice-Grade

Each 6-inch cable uses 28 AWG pure-copper conductors wired from RJ11 pins 2-3-4-5 to RJ45 pins 3-4-5-6. The couplers accept Cat5, Cat5e, Cat6 or Cat7 patch cables with 8P8C connectors. This pin mapping carries analogue voice or DSL signals but does not pass Ethernet data, so broadband traffic from a router will not function through the link.

Gold-Plated Contacts and Shielded Couplers

The RJ45-to-RJ11 cables feature gold-plated metal contacts to maintain a low-resistance path for voice quality. The RJ45 couplers use ABS housings with metal shielding to reduce interference on the Ethernet cable run. No active electronics are present, so the kit draws no power and adds no noise to the line.

Questions about this item

Will the 28 AWG RJ45-to-RJ11 cables work with my existing Cat5e or Cat6 wall runs?

Yes, the female-to-female RJ45 couplers accept Cat5e, Cat6 and Cat7 cables, so your current Ethernet wiring can carry the telephone signal.

How can I verify the adapter kit is passing a dial tone correctly after I plug everything in?

Pick up the connected handset and listen for a clear dial tone; the gold-plated contacts on the RJ11 plugs are designed to preserve voice quality.

The box lists two 6-inch RJ45-to-RJ11 cables and two RJ45 couplers — do I need any extra cords or tools?

No extra items are required; the two short cables and two couplers connect directly to your Ethernet cable and telephone equipment.
