已注册的Jack 11或简称为R-J将电缆插入墙上插座的连接接口或连接器。 通常，RJ-11也被称为调制解调器端口，电话连接器，电话插头Kong或电话线。

RJ-11接线2或4针 (RJ-11 Wiring 2 or 4 Pins)

There are male and female RJ-11. RJ-11 has 6 connector positions but in general 2 or 4 of them are used in practice. Generally untwisted and unshielded twisted pair (UTP) cables are used to end with RJ-11 connector. We can see below that RJ-11 is implemented as 4 connecting cables with 4 pins.

有公母RJ-11。 RJ-11有6个连接器位置，但实际上通常使用2个或4个。 通常，非绞合和非屏蔽双绞线(UTP)电缆用于RJ-11连接器。 下面我们可以看到RJ-11实现了4个4针连接电缆。

In the following example, only two pins are used and other pinholes are not used for a cable connection.

在以下示例中，只使用两个插针，而不使用其他针Kong进行电缆连接。

6 pins can be used in rate situations for telephones. 6 pins RJ-11 can be used to connect 3 phones to the telephone line.

6个引脚可用于电话费率。 6针RJ-11可用于将三部电话连接到电话线上。
