USB-A to RJ11 telephone adapter

The Trisonic SN-U205 provides a USB-A female port on one side and an RJ11 6P4C jack on the other. It is intended for home or business telephone applications where a USB-A connection must be converted to a standard phone line plug. The adapter comes in black and is supplied as a single unit.

RJ11 6P4C jack width

The decisive specification is the RJ11 6P4C jack width of 3/8 inch. This dimension determines whether the adapter will mate with the telephone cable or wall plate in your installation. If your equipment requires a different jack width, this adapter will not fit.

Build integration

The adapter needs a USB-A male plug from the host device and a standard RJ11 6P4C telephone cable to complete the link. It frees up the need for a dedicated USB-to-serial or proprietary telephone dongle by using the common USB-A interface. Buyers who require a different connector type or a wider jack cannot use this unit.

Questions about this item

What does the USB-A female to RJ11 6P4C conversion actually do when I plug it into a computer?

It provides a physical socket so a standard telephone cord with an RJ11 6P4C plug can connect to a USB-A port, but the computer must supply the correct signalling for the attached phone device.

Which interface standard does the USB-A female side follow and what does that limit?

The USB-A female side follows the USB-A mechanical standard; it limits the connection to the signalling and power the host port provides, not to Ethernet or networking speeds.

What clearance do I need for the RJ11 6P4C jack to fit?

The RJ11 6P4C jack measures 3/8 inch wide, so allow at least that much horizontal space plus room for the telephone cord to insert without strain.
