About ADSL Splitter
Recently my company fax machine does not have tone and customers could not send their fax to our office. Since the internet line was working i did not suspect it was the ADSL splitter fault. Later when i used another good working ADSL splitter to confirm it i found that indeed the ADSL splitter phone circuit have problem but the modem line was working. I opened up the splitter and found only five components inside. The splitter consists of only two resistor, one capacitor and two coils. This is a cheap ADSL splitter and cost about USD3.00.
Then i check on the components and guess what? found a small coil that have open circuit when i tested it using multimeter Ohm’s range. Here are the photos of the ADSL splitter internal section and the faulty coil:
