call indicator的用法详解
Call Indicator（拨号指示）是一个使用在电话安装中的表示设备，用来告知电话使用者是否成功拨号或正在尝试拨号。它是由一个灯泡组成，在两个电话之间的拨号时，拨号指示发出一个清晰的双声灯泡信号，当电话拨号号码正确时，拨号指示出现在发起通话的电话上的灯泡会闪烁，以表示电话正在尝试拨号。当拨号成功时，拨号指示灯会发出一个清晰的长音灯泡信号，这表明两个电话之间的连接已成功建立。
Call indicators are generally used in pairs, with each telephone having one. A call indicator, also called a calling lamp, is a small incandescent, flashing or steady-burning light mounted on the phone. Upon making a call, the caller's call indicator will flash while the subscriber at the other end will have a steady light. When the call is answered, the caller's call indicator will cease flashing and the receiver's will turn off.
Call indicators can be found on both wired and cordless telephones. They are typically located on the front or side of the phone. On cordless phones, the call indicator may be a single button located along the top of the handset. Some phones also have a switch to enable and disable the call indicator.
Call indicators are useful for providing visual confirmation when a telephone call has been made or received, especially in noisy environments. They can also provide assurance that a telephone call has actually been made, in addition to providing a visual reminder that the phone is in use.
