The 4P4C connector is the standard modular connector used on both ends of telephone handset cords, and is therefore often called a handset connector.. This handset connector is not a registered jack, because it was not intended to connect directly to . Copper Cable Assemblies. Don't let patch cords be the weak link in your network investment.

Archived from the original on The TA and TB standards are used in place of RJ61 so that a single wiring standard in a facility can be used for both voice and data. Instead, cables are usually connected using a female-to-female adapter , having two jacks wired back-to-back. Establishes a bridged connection for one telephone line with key telephone system control ahead of line circuit. Two of the six possible contact positions connect tip and ring, and the other two conductors are unused. The cable between the computer and the keyboard was a coiled cord with an appearance very similar to a telephone handset cable. For a multi-line interface such as the RJ21 which provided 25 pairs , the customer must denote which position s of the interface are to be used.
A modular connector is an electrical connector that was originally designed for use in telephone wiring, but has since been used for many other purposes. Many applications that originally used a bulkier, more expensive connector have converted to modular connectors.
Probably the best known applications of modular connectors are for telephone and Ethernet. Modular connectors were originally used in the Registration Interface system, mandated by the Federal Communications Commission FCC in in which they became known as registered jacks.
The registered jack specifications define the wiring patterns of the jacks, not the physical dimensions or geometry of the connectors of either gender. Other systems exist for assigning signals to modular connectors; physical interchangeability of plugs and jacks does not ensure interoperation, nor protection from electrical damage to circuits. For example, modular cables and connectors have been used to supply low-voltage AC or DC power and no clear standard exists for this application.
The term "modular connector" arose from its original use in a novel system of cabling designed to make telephone equipment more modular.

Deep into her, my pelvic motion driving it so far into her, that she screamed with ecstasy. Он зубами снял наконечник, звонко шлепнул Вику по бедру в чулке и тут же ввел иглу.
A registered jack RJ is a standardized telecommunication network interface for connecting voice and data equipment to a service provided by a local exchange carrier or long distance carrier.
The specification includes physical construction, wiring, and signal semantics. Accordingly, registered jacks are primarily named by the letters RJ , followed by two digits that express the type. Additionally, letter suffixes indicate minor variations. For example, RJ11 , RJ14 , and RJ25 are the most commonly used interfaces for telephone connections for one-, two-, and three-line service, respectively.
Although these standards are legal definitions in the United States, some interfaces are used worldwide. The connectors used for registered jack installations are primarily the modular connector and the pin miniature ribbon connector. For example, RJ11 uses a six-position two-conductor connector 6P2C , RJ14 uses a six-position four-conductor 6P4C modular jack, while RJ21 uses a pair pin miniature ribbon connector.
The registered jack designations originated in the standardization processes in the Bell System in the United States, and describe application circuits and not just the physical geometry of the connectors; inspection of the connector does not necessarily show which registered jack wiring is used.
The same modular connector type may be used for different registered jack applications. Strictly, Registered Jack refers to both the female physical connector modular connector and its wiring, but the term is often used loosely to refer to modular connectors regardless of wiring or gender, such as in Ethernet over twisted pair. There is much confusion over these connection standards.
Flight has always fascinated humanity. So it's no surprise that, when powered-flying machines were invented at last in , they were considered to be cool. As aircraft became more commonplace over the decades, though, only the most awesome among them ascended to true Cool Plane glory. Despite this, Real Life aviation has produced more examples of the Cool Plane than many fiction works put together - so much so that a lot of writers are satisfied to just use Real Life planes in their works without having to imagine their own.
It should also be noted that all real life aircraft have both flaws and limits. What is ok with one might be fatal with another. The Dawn of Flight. The first case of powered flight itself should count as pretty cool.
Granted there is a bit of controversy over which plane was the first. Most people know the Wrights were first to achieve sustained and controlled powered flight, as documented by witnesses and photographs. But many others have also claimed the honor of the first powered flight, though not necessarily the "sustained and controlled" part, with various degrees of documentation.
Perhaps the best documented alternate claim is that for Brazilian national hero Alberto Santos-Dumont. Even in the US, there was considerable controversy over who flew first. Samuel Pierpont Langley designed a series of small-scaled unpiloted aircraft, all named Aerodrome.
A week and a half later, the Wright Flyer had its successful day of flights. The Aerodrome successfully flew in after considerable modification by Glenn Curtiss, and the Smithsonian Institution, which had sponsored Langley, declared the Aerodrome to be the first design capable of powered flight disregarding that the Curtiss-modified aircraft was considerably different and without acknowledging any of Curtiss' 93 modifications.
