    PROS: The product works really well; Super fast
    CONS: None specified
    I have a fax machine backed up against a wall, and the phone wire gets inserted into the back, so when I have to hook up the phone wire, I cannot see where to plug it in. I have to feel for the hole. So I bought a short length of phone wire, and this inline coupler, so I can more easily hook up the fax and see what I am connecting. It works very well

    6P6C couplers, cables and splitters are mainstays for model railroaders using Digital Command Control to run their railroads. Your selection and product descriptions are top notch. Oh yes, the RJ12 Inline Coupler was exactly what I needed and it worked perfectly.

Q: What is the difference between an RJ11 and an RJ12 connector?

A: Both connectors are the same size and appear the same. However, looking at the contacts an RJ11 will only have 4 contacts. An RJ12 will have 6 contacts.

Q: What are the terms 4P4C, 6P4C and 6P6C referring to?


4P4C: 4 Position 4 Conductor ( RJ22) - used for Telephone Handset cables.

6P4C: 6 Position 4 Conductor (RJ11) - used for ADSL, telephone, and modem cables.

6P6C: 6 Position 6 Conductor (RJ12) - used in System phones.

Q: Which adapter or splitter should I use. Reverse or straight?

A: Newer phones can use a straight or reverse pinned line cord. If you’re unsure of the age of your phone a reverse pinned cord will work with any age phone
