| dc.description.abstract | Caller ID (caller identification or CID, and more properly calling number identification - CNID) is a telephony intelligent network service that transmits the caller's telephone number and in some places the caller's name to the called party's telephone equipment during the ringing signal or when the call is being set up but before the call is answered. In the USA, CNID is typically transmitted digitally using Bell 202 modulation between the first and second rings, but in other countries other methods are also used. Instead of sending the caller ID in between the first and second ring, some systems use a "line reversal" to announce the caller ID, or caller ID signals are simply sent without any announcement. Instead of Bell 202 the European alternative V.23 is sometimes used, (without the 75 baud reverse channel) or the data is sent using DTMF signaling. Caller ID system is a feature of digital telephone network, which allows the telephone number of the caller to be transferred to the called person before he/she answers the phone. This feature can be useful for example for storing numbers of the people who have tried to call you when you were not home. This feature is nowadays activated so that the caller number is transferred always to the telephone central near called person. If the called person wants to get that information, he/she must order this service from telephone company.Features and Benefits: Instantly know who's calling: caller id displays the caller's name and number after the first ring, so you can decide instantly whether or not to answer.Saves call information: caller id saves names, numbers, dates and times of incoming calls .It makes returning calls simple.Time saving: your time is valuable .If you know who's trying to reach you ,you can determine if the call is important or not .you will avoid the hassle of unwanted callers and spend your time doing what you want to do.Blocked Calls: At your option, unidentified or anonymous, out of area, blocked and private calls are not allowed to ring your phone.
