RJ11 stands for “registered jack” and was originally designed by phone companies in the 70's and is used for analog voice lines.
The key distinction between RJ9 and RJ11 is that the RJ9 is only available in one configuration, namely the 4 P4C connection type. RJ11, on the other hand, has two different configurations. The connection types are 6 P2C and 6P4C, respectively.
RJ11 is an older version of RJ12, and they are the same size. The difference is that RJ11 uses four internal wires (called conductors) while RJ12 cable uses six. RJ12 is backwards compatible with RJ11, but RJ11 will not work with RJ12.
Most other letter markings indicate that a piece is gold-plated or gold-filled. Gold-plated pieces may be marked 'GP,' 'GE,' or 'HGE. ' 'GP' or 'GE' means the piece is electroplated with a thin layer of gold; '18K GP' would indicate a piece plated with 18 karat gold.
Inspect the Hallmark
Hallmarks are distinguishing characteristics that are stamped on gold, silver and platinum items - typically to identify the items purity. There are also hallmarks that can identify where the item was made (called a makers mark), the office the metal was tested in, the year, and the designer.
Gold Purity Marks
Purity marks on gold jewelry will consist of a two-digit number followed by the letter “k,” or a three-digit number. The letter “k” refers to karats, where pure gold is composed of 24 karats (24k).
If the metal doesn't change throughout the cut, the jewelry is more than likely solid gold. Gold plated jewelry will typically have a line of demarcation in the scratched area where the gold plating ends, and the base metal begins.
Look at the Hallmarks – Jewelry hallmarks are markings on the post, band, or clasp that indicate the piece's country of origin or its metal content. If the piece doesn't have a hallmark, it's either because it's too old, as hallmarks weren't used before 100 years ago, or it's not made from a precious metal.

Modern rolled gold jewelry should always have a stamp that indicates how much gold is used and its level of purity. Often times the letters "RG" indicate that the metal used is rolled gold. Sometimes pieces have "RGP" instead, meaning "rolled gold plate."

Lead has often been used in jewelry, to make the article heavier, brighten colors, and to stabilize or soften plastic. However, lead can be dangerous, even deadly when used in jewelry. The state of California regulates lead in jewelry to help prevent it from harming people.

Look for a Letter Mark
If the item of jewelry has the letters GP, GF, or GEP stamped on it, these indicate that it is not made of real gold. GP means it is gold plated, GF means it is gold filled, and GEP means it is gold electroplate. That is, the jewelry is made of some other metal with a thin layer of gold on top.
Gold-plated jewelry is made by electroplating a thin layer of gold onto a base metal, which can be copper, brass, or another metal alloy. If the base metal used in the gold-plating process contains allergenic metals like nickel or copper, then the gold-plated jewelry may cause allergic reactions in some individuals.
The most common stamps used to mark gold plated jewellery are GP standing for “gold plated” and GEP meaning “gold electroplated”. Heavily gold plated items are marked as HGP, while heavily gold electroplated jewellery is marked as HGE.
RJ12 is a 6P6C wiring standards means, 6 positions of the socket will be occupied by 6 conductors or wires. Normal home telephones used RJ11 and corporate PBX using key phones or Digital Phone Systems uses generally RJ12.
The difference is in the number of positions available on the connector and the number of contacts actually present. Obviously where there are more positions the connector is necessarily larger.
