More commonly known as a modem port, phone connector, phone jack or phone line, the Registered Jack-11 (RJ-11) is a four or six wire connection for telephone and Modem connectors in the US.
What is an RJ11 port?
A. J. R. (Registered Jack-11) A telephone interface that uses a cable of twisted wire pairs and a modular jack with two, four or six contacts. RJ-11 is the common connector for plugging a telephone into the wall and the handset into the telephone.

What is RJ11 in networking?
RJ11 is the cable connector that using in telephone sets while RJ45 is used in networking, where you connect computers or other network elements to each other.
Can I plug RJ11 into RJ45 port?
Warning – Don’t plug an RJ11 plug into an RJ45 socket RJ11 plugs can permanently damage your RJ45 socket. DO NOT DO THIS because it may damage the RJ45 socket by pushing pin 1 and pin 8 so far into the housing that they may never return to their former positions when the RJ11 connector is removed.
Can you use RJ11 for Internet?
It’s what plugs into the back of your computer. It is possible to physically fit an RJ11 connector into an RJ45 receptacle, however this will never function for an actual Ethernet connection. The reason is that the RJ45 connector has 8 pins, while the RJ11 has only at most 6.
Is RJ11 analog or digital?
Analogue. There’s nothing the least bit digital about RJ11, and it also has very little to do with cable, but many people mistakenly believe that the 6 position modular connector is what “RJ11” means, and that same connector is in fact used by many digital phone systems.
Can I use a RJ45 jack for phone?
You can even use RJ-45 wall jacks for phones because RJ-11 plugs will fit, though you can only access up to two pairs or 4 wires in the RJ-45 wall jack. You can see this in many office buildings, and if they use RJ-45 jacks for both data and POTS phone the jacks should be marked and are usually a different color.
Can you plug a phone jack into an Ethernet port?
2 Answers. You can plug standard “square” RJ14 cables into a RJ45 jack, as long as the port is wired to your phone line. It should click in.
Can I use RJ11 instead of RJ12?
RJ12 is backwards compatible with RJ11, but RJ11 will not work with RJ12. Coiled handset cords use a smaller connector called RJ9 or RJ22 (both names refer to the same thing). These are physically smaller than RJ11/RJ12 and use four conductors.
Can an Ethernet cable go into a phone jack?
An Ethernet cable won’t fit into a phone jack. But a phone cable will fit into an Ethernet jack. If your house has Ethernet wiring, the difference between a phone and Ethernet connection is what’s on the other side of the cable. Generally, the Ethernet cables will all go to a low voltage panel.
Can I use RJ45 instead of RJ11?
Warning – Don’t plug an RJ11 plug into an RJ45 socket RJ11 plugs can permanently damage your RJ45 socket. Data cabling systems normally use RJ45 connectors. The right way to use an RJ11 connector in a data cabling system is use an RJ11 to RJ45 adapter.
What kind of plug and Jack does a RJ11 telephone use?
RJ11 Telephone. The six-position plug and jack commonly used for telephone line connections may be used for RJ11, RJ14 or even RJ25, all of which are actually names of interface standards that use this physical connector. The RJ11 standard dictates a 2-wire connection, while RJ14 uses a 4-wire configuration, and RJ25 uses all six wires.
What does RJ-11 stand for in modem port?

What’s the difference between RJ11 and RJ45 ethernet connectors?
RJ45 connectors can support 10Gbps over Ethernet, provided the other equipment like network cables also support that speed. RJ45 plugs are long and rectangular, with a width of just under 11.65mm. RJ11 plugs are square and shorter, with a width of 9.65mm. Here are some pictures of RJ45 and RJ11 connectors and jacks:
