Telephone & Exchange Tester
ETT 10
Maintenance statistics of telephone networkshave shown that for most of the failures, theexchange - line - subscriber (EXCH-LINE-TEL) sections are responsible. Accordingly, the first step of the troubleshooting procedure is to locate the breakdown spot, i.e. to find out whether thefailure source is within the exchange, the subscriber site or in the line (local loop). Thisproblem can be easily solved by theTelephone & Exchange Tester ETT 10, in most cases without requiring the technician to visit the subscriber or the junction boxes along the line.

Digital Signal Identification
There are times when using a conventional test telephone or other device to check whether a line is "dead" before cutting it down just won't work. One example is where a cable can be carrying an "out-of-band" service, like ADSL and VDSL, which are inaudible using conventional monitoring equipment. T-Bug will specifically identify the nature of the service on a line, whether xDSL or ISDN, while the DigAlert™ probe will warn if any high frequency signal is present. Check before you cut.
