Electrical Question from Rong about Telephone Wiring
Background: Rong, a Homeowner from Fremont in California

[ad#block]Question: There are two sets of phone jacks in my house. Only one set is working. The not working jack sets are in good reach area, so I wonder if I connect one of them to a working jack, then all the jacks will work. Thanks,

Dave’s Reply:
Thanks for your electrical question Rong.
Changing the wiring configuration of the existing system would require identifying what is connected at present. This in itself will most likely reveal why the phone jacks in question do not work, and how you might fix then. The phone jacks that do not work may simply be because they have been connected previously to a different pair and used assigned to a separate telephone number. If this is the case then it is a simple matter to swap the connections to be placed on the desired working pair, either at each phone jack or at the main terminal block. Pay careful attention to the colors of the pairs of wires. Compare the colors of the pairs to the wiring diagram found on this website using the link provided below.
