It means Connector type 11 of the RJ specification; RJ means Registered jacks - it is a telephone standard developed to standardize connectors in the telephone industry.
The type of connector is used by the analog modems is RJ11 or RJ45.
rj11
RJ45 is used with ethernet cables in computer networking while RJ11 is used in connecting telephone units.RJ45 contains more wires than RJ11and RJ45 is physically bigger than RJ11 to accommodate the extra wires
RJ45 is a 8 pin connector used on networking(ethernet) cables RJ11 is 6 pin connector used on telephone cables in the USA
XJACK is a type of connector to attach a standard RJ11 or RJ45 plug directly to a PC
An RJ11 connector is a six-position two-conductor connector. An RJ9 connector is a term for a four-position, four-conductor connector that is often used to connect a handset to the base of a telephone.
An RJ45 connector and a PCI NIC card are 2 completely different things. An RJ45 (Technically an 8P8C) is the connector at the end of a CAT cable which plugs into a NIC card. Unless you are thinking RJ11, which has nothing to do with CAT cables. An RJ11 is the name of the cable used for single-line dialup modems and telephones, in which case, the connector is called a 6P4C connector.
No, a conversion can not be made due to the different size of cables that each terminal end uses. An RJ45 uses a Cat , 8 wire cable where as a RJ11 uses a smaller 4 wire cable. The sockets for the RJ45 will be too wide to allow a RJ11 connector to securely connect to it.
RJ11(Registered Jack-11) has 4 to 6 pins. Generally 4 ports are there in RJ11.
You cannot connect an RJ11 cable to a RJ45 port. You can buy an external dial-up modem, though, that connects to a USB port. A link to where you can buy an external USB dial-up modem is below. http://www.amazon.com/Small-Compact-Lightweight-Modem-Connect/dp/B001C4EUFE
rj45 which is the large one but bt use rj11 whichis smaller
The RJ11 is found in all new homes the jack is found on a wall. thanks
