Can not break dial tone

New Poster

Can not break dial tone

Recently switched from AT&T to Voice with 2 different phone number lines.  I can not break dial tone now on line 1 with my Panasonic Wireless system (KX-TG6702 base with 3 handsets).   Can't break dial tone means the dial tone is constant, even when dialing. Therefore, the call will not go out.  Note: When touch tone phones 1st came out many years ago, a similar problem would have been because the Polarity was reversed on the phone lines. 

 

I am using 2 seperate phone line cords from the modem to the Panasonic base unit.  However, when I plug in a different corded AT&T phone into the #1 line's port on the modem, I can break the dial tone & can then make a call out.  

 

I have Filed 3 case #'s, including tech coming to check it out.  Once here, he ran test & stated its the phone's problem.

 

They have tried everything but replacing modem, (Xfinity supplied ARRIS TM822G/CT).

 

1) Are there any solutions to resolving this?

2) Is there a quality cordless phone system which WILL work with this modem?

3) I am even willing to go down to just one line if this will resolve the problem.  For now, I have used the corded phone to Call Forward the 1st line to the 2nd line.

Re: Can not break dial tone

If your using two separate phone cords to the cordless base, then make sure you are using only a 2 wire phone cord on the L1/L2 jack on the eMTA telephony modem.

 

If the phone has a RJ14 2 line jack, then you don't need the 2nd phone cord, since the L1/L2 jack has both line 1 and line 2 on it.  If you add the second cord and the first cord is a 4 wire cord, then your have both L2 on the 2nd pair, and L2 on the first pair on the L2 jack on the eMTA, whic might be shorting out the 2 lines.

 

On the eMTA the L1/L2 jack is wired as a RJ14 jack with both lines, line 1 on the center 2 conductors, line 2 on the 2nd and 4th conductors.   The L2 jack is the 2nd line only wired as a RJ11 jack with the second line on the center 2 conductors.

 

Modern electronic phones also have polarity guards built in, so the polarity of the phone and jacks is no longer a issue, unless a older touch tone phone is involved.  A simple LED telephone tester always confirms the proper polarity of the jack.

 

 

 

If your using two phone cords, then the cord on line 1 must be a 2 wire cord like this one.

Re: Can not break dial tone

I removed both phone line cords.  Then took a 4 wire phone cord and plugged it into the L1/L2 jack on the eMTA and the other end into the L1/L2 on the cordless base unit.  I also recycled the modem.

 

Unfortunately, it has made no difference.

 

Note: When I dial the phone number for Line 1 from Line 2, they can hear my voice but I can not hear them speak.
