Simple enough. On the cabinet, there are at least 8 modular jacks. One is marked LCOT 1-4 and the other is marked DHLC 1-4. Swap the moduler plugs for LCOT 1 and 2. If the No Dial Tone moves to line 2, it's a telco issue (most likely). If it stays on line 1, it's a system issue.

I'm betting on the former.

TD-1232 PBX - is is a programming issue or hardware issue?


ok so the first thing you should do is to get to where your PB X connects to the lines and ensure that there is a standing voltage on the lines. usually 50 v dc in the uk.

check each line has 50 volts with a multimeter when nthey are not active.

if line 3 has no voltage your problem is the line.

if line 3 does have voltage at 50 v idle ring the lines out 1 then 2 then 3 foir a analogue line to present ringing bthe voltage increases and is in cadence with the ringing. if again the voltage does not increase during the ringing cycle then the problemn is again with the line.

if the line 3 has 50 v idle and increase in voltage during ringing, then the problem is the line interface in the PBX

hope that this helps all above is for analogue lines only

On the intercom dial *7510 (*7511 turns it back on in a TDA-50 or lower) and *751x (1 or 2) turns it on in a 100 or larger.

Have 2 lines on my panasonic phone, the first line has no dial tone


Do you plan on doing anything to help yourself? In a room somewhere, there's a Black and Blue cabinet wiht jacks on it. One of those jacks is the one that contains dial tone for line 1. You also have an interface somewhere that has line 1 and it has a modular jack to plug into (usually). You have to take a REGULAR phone, not the Panasonic digital phone, and plug into the line to determine if it's inside or outside trouble. It will probably be outside, then you report it to whoever supplies your phone lines.

If it is inside, you can always swap the plugs for lines 1 & 2 to see if you have a programming issue. This assumes you have a TDA-50 or lower or NCP phone system. If you have a TDx-100/200/600 then you need to be a little more familiar with troubleshooting.

I have a phone system in my house using the KX-T7633 model corded phones. I want to plug in a cordless phone in the back of the KX-T7633 so that I can be cordless, but when I do I can not get a dial tone...


In a TDA-30/50 there are FOUR super hybrid ports, the first 4 on the cabinet. In a TDA 100/200/600, there are NONE. Which one do you have and is your extension 101-104? If not, it won't work. You can probably wire an analog port to the first pair and use the same cable, but it will never merge with the digital set.

Is tha possible to get 25 single lines on 16SLC card(50 pin)


The 25-pair Amphenol connector is just something the industry uses because it's standard and easy. In a TDA system, the 8-port C.O. Trunk card uses the first 8 pairs, a 16-port the first 16 pairs, an 8-port Pana station card uses the first 24 pairs, 3 pairs per extension. The last pars don't have any hardware behind it and are connected to nothing.

The only phone system that I remember where all 25 pairs are used is a 1a2 10 button set and, maybe a Comdial system where the 25th pair is the common audible for station 17 :-)

Panasonic KX-FM220 fax machine does have a dial tone


I would double check your phone cord. There is usually 2 jacks in the back of the fax machine. 1 is for Line, and 1 is for phone.
Your phone cord should be hooked up in the LINE jack that goes to the wall.
I would also double check your phone cord on another phone to make sure the cord is good.
If you look at the clear connector that you plug into your wall and fax machine, does it have 4 copper/gold color wires contacts imbedded in the clear plastic connector?

Another thing to try, if you fax machine has a Line and a Phone connector, try plugging in a phone in the PHONE connector. Then hook up another phone cord going from the LINE to the WALL jack.
If you get a dial tone on your Phone, then you know you have it connected correctly. If no dial tone, then I would go back to the phone cord.
check those things and get back to me and I will see if I can help you with more suggestions.
Good luck.
Mac =)

Make sure the phone is pluggd into the wall properly. If so and no dial tone is detectable make sure you installed the batterys on the handsets correctly and that they are fully charged. If you have a friendly neighbor with a working phone line plug youre phone into their line and if it does not work and you followed my previous instructions seek a repair center in youre area that honors panasonic warranties. If the phone is pluggd in at the neighbors house and it works use it to call the phone company.
