Re: Basic Faxline Install by tech or self

Re: Basic Faxline Install by tech or self

I have two telephone lines, one dedicated for fax and after months of dealing with fax line not ringing therefore not receiving, I managed to get the fax line to ring. There are two outlets in the modem and the telephone outlet has a splitter, one line connected to the wall jack and the other to the telephone. The second line  will only ring when nothing is plugged into the telephone outlet.  Therefore, if I know I am going to receive a fax, I un plug the telephone connection to the modem.

There has to be a better way.

Re: Basic Faxline Install by tech or self

On the eMTA, the first jack is L1 & L2 in a RJ14 arrangement.  That supplies you both lines on that jack to feed the inside wiring in the home  The 2nd jack on the eMTA is for the 2nd line only on a RJ11 arrangement.

 

What most likely is happening is on the L1/L2 jack feeding the inside wiring, there is a short or cross on the 2nd pair.

 

The 2nd line on the first jack needs to be isolated not to feed into the inside wiring in the home.  That or the inside wiring needs a total going over to find the issue with the 2nd pair.

 

You can band-aid it by adding a L1/L2 phone line splitter on the 1st jack on the eMTA and then only feeding the 1st pair (line 1) to the inside wiring.  Othewise, you should hire a local low voltage wiring specialist to go over the inside wiring and find and fix the short or cross on the 2nd inside wiring pair.

 

You can also try to use a 2 wire phone cord from the eMTA's L1/L2 jack to feed the inside phone wiring.  Using a 2 wire phone cord will block the 2nd line pair from entering the inside wiring in the home.

 

 

Here's a 2 wire phone cord that might help.

Here's and example of a L1 / L2 phone line splitter.  The L1 would be connected to feed the inside wiring.
