"Down Line" Tap Detector detects eavesdropping/wiretapping that previously had been undetectable. It detects remote extension drawn loop wiretapping / electronic surveillance connecting and disconnecting from your telephone line. It continuously protects your telephone, fax and computer data communications to a degree never before possible. It is the first and only telephone line security device that can detect electronically isolated remote extension drawn loops; the most sophisticated, threatening and common type of electronic surveillance that other security devices cannot detect. 

This device is most effective at detecting wiretaps / eavesdropping at the beginning and ending of a telephone call. At the beginning of a telephone call when someone is calling you watch for a remote extension drawn loop wiretap to seize the line between the cadence ringing, usually between the first and third ring creating a connection reaction.

At the conclusion of any telephone call by observing the C3I and counting / timing the number of disconnection reactions on the telephone line this device can detect legal and illegal wiretapping on your telephone line by establishing either a normal signature pattern or an abnormal signature pattern resulting from additional telephone lines / wiretapping equipment disconnecting from your telephone line.
