Topcat's Budget Telephone System- Panasonic KX-TA624 Conquest

Re: Topcat's Budget Telephone System- Panasonic KX-TA624 Conquest

I find cellular connections to have horrible quality! That's largely the reason for keeping the land line (that and the fact that it "never" goes down)

This one actually sounds very good. Not great, but very good. It actually sounds a bit better than my cell phone (samsung note 3). For its purpose, its fine. It won't be heavily used.....I just needed anohter contact number besides my cell. What makes this a little more unique are the internal functions of the system. I dropped 3 cat5e cables in the ground connecting the shop to the house. I'm only using 2....so I can have up to 4 extensions from this system at the house as well.

I've used vonage and magic jack in the past (the only consumer VOIP options I was aware of; I'm not even sure if they're still around)....they were miserable for quality.

Wow! That's outrageous! We have CL here but the bill is half what you're being quoted (our internet connection comes from a different carrier).

Yea....now the little straight talk box makes a little more sense. I haven't tried it, but the only thing I probably won't be able to do with the straight talk box is fax. According to their documentation, you can not transfer data over this thing....but I have not tried it.

[I'm not keen on letting my neighbors know that my phone is ringing so it isn't used unless needed! (I also have a PA system out there but that's even MORE offensive!) :< ]

I'll put the big bells out in the garage.... My nearest neighbor is quite a ways away....I doubt they'd hear it.

For the reasons by Redwire.....horrible quality.

My internet connection isn't the fastest....I don't need anything else clogging it up.

Ah, that's a factor. I wanted two ways to contact the house: internet connection and PSTN (FXO gateway lets the PSTN interace to my local internet)

Only 2 carriers available. 1) AT$T = $77/mo, 2) Centurylink (also my internet provider) $72/mo + my internet service costs. No thanks.

I did the same when I built my house and remodeled/added onto my shop. 14 drops in the house, 44 in the shop. I'll run additional cat5e for POTS, easy to repurpose later if needed.

That's the mistake that I made... The CAT3 was free and the 5,000 ft of CAT5e cost a pretty penny -- no desire to add another 1,000 ft to that bill! :<

But, even if I wanted to do so, I'm running out of ports on the main switch (I'm at 120 presently and each new port represents a potential ~25W load).

I've got one sitting in a box. Old Western Electric large wall-mount ringer box with big bells....circa 1930's. I have an old hand crank phone magneto with a ~100v 20Hz output (what it takes to ring mechanical phone bells)....I tested it, it's loud!

Mine is a small unit about half the size of a Trimline phone. Mechanism is largely the same as in those phones but a bit beefier. Normally, I wear a BT earpiece to tell me of an incoming call (after it has been screened). But, if I'm outdoors and not wearing it, the external bell can be rung to get my attention.

I have a Northern Electric ringer box, with a Western Electric 22A magneto in it. I need a new gear, it is worn out. Ringer sounds great. You can put a few uF cap to POTS and it works.
I even have the original schematic on the door.

Very important the protective earth-ground is connected, POTS has lots of lightning transients.

It is all grounded, on surge protection, and UPS systems.

Why not go for a consumer VoIP plan?

For the reasons by Redwire.....horrible quality. My internet connection isn't the fastest....I don't need anything else clogging it up.

I don't understand why that would be the case. Our land line is ~$30/month including the various taxes and fees.

Only 2 carriers available. 1) AT$T = $77/mo, 2) Centurylink (also my internet provider) $72/mo + my internet service costs. No thanks.

I ran CAT5e...throughout the house (25 drops).

[You might also consider putting an external ringer on the outside of your building to "signal" you when you're out in the yard, etc. I have one in the back yard but now have other mechanisms that have rendered it "unnecessary"]

Re: Topcat's Budget Telephone System- Panasonic KX-TA624 Conquest

Why am I wasting my time on this you wonder? Well, I need a phone number for a little venture I'm working on....and I sure as hell don't want my personal cell phone number out there.....

Why not go for a consumer VoIP plan?

The cheapest I could get a land line is ~$70-$80 a month.....that's fracking ludicrous!

That was all the easy part.....the real fun lies ahead, wiring the building for all this!! ...so yea, this will be an ongoing project!

I ran CAT5e, CAT3 and RG6 throughout the house (25 drops).

I regret running the CAT3 as it's really only useful for POTS. But, I'm stuck with it as it all terminates in a location that doesn't have convenient access to power or space for a switch.

But, I've opted to remove all of the RG6 drops and replace them with a second set of CAT5e drops. I figure this lets me run phone, audio or video to any of those drops in addition to "computer" access.

So, probably 1000 ft of RG6 got scrapped (thankfully I didn't pay for any of it!)

Re: Topcat's Budget Telephone System- Panasonic KX-TA624 Conquest

That looks really nice
This is from an era when phones worked like they should, and had good sound quality and good quality parts. Great in an office setting. I'm not sure how many outside lines this unit can handle.

Have you looked at VoIP modems, to pipe this through your Internet connection? My buddy uses free VoIP services and they all sound terrible and drop calls. It's the worst echoes, clicks, distortion, dropouts etc. Eventually they get bought up or go out of business. Not everyone wants to pay for it.

About 10~12 years ago I was given this Panasonic KX-TA624 analog telephone system with its 'master phone' and box full of extension telephones. It's been up in the attic all this time, untouched/unused since I didn't have a land line. It has all the line expansion cards, making it able to handle up to 6 outside lines and 24 internal extensions. I was told this system was removed from a shopping center that upgraded to a VOIP system.

Why am I wasting my time on this you wonder? Well, I need a phone number for a little venture I'm working on....and I sure as hell don't want my personal cell phone number out there..... Now here's where it gets good!!! The cheapest I could get a land line is ~$70-$80 a month.....that's fracking ludicrous! Another cell phone would be more than that once I factored in the monthly costs plus the cost of another phone....and I refuse to be one of those bozos that think they're so important that they need to carry multiple cell phones.... Ok, so here's what the solution was.....a straight talk wireless 'Home Phone' box, which is compatible with any corded/cordless 'landline' telephone...hmmm, worth a little gamble to see if it'll work with this system. The box itself cost me $30. The service is $15/mo, unlimited talk & long distance....DONE DEAL!

....so here we go!! The phone network switchboard/controller:



Box full of phones and random wires...



This thing was dusty & dirty....I completely disassembled it, washed the plastic housing in the sink and blew the dust off the boards with my air compressor hose.

All Apart....I checked the caps in the PSU.... A panasonic unit with all Panasonic caps! What could go wrong!!



The boards:


A hard-mounted 'memory' battery.....hmmm... It was a miracle, 10 years in the attic with season after season of extreme heat and extreme cold, this battery wasn't dead! It was holding 2.7v.



Just to avoid headaches later, I simply harvested a socket from a junk motherboard and installed a fresh battery....a Panasonic no less!



All cleaned and going back together.





Testing.... I tested all this for a good 2 months before today just to make sure everything works and is compatible. The 'straight talk' box never missed a beat, incoming or outgoing. Audio quality is very good, never had any drops. The Panasonic system uses proprietary phones.....but researching & testing revealed that it will also work with standard landline phones as well; albeit some of the internal features won't work, but all the basic functions will. Not to mention, that even as old as this system is, it's still very well supported even today. Add-ons, phones, and other accessories for this system are still readily available and inexpensive! Now for the vintage phone test....The 'straight talk' box does not support Pulse dialing....but lo & behold, the switchboard does, and does all the DTMF translation internally!! I love the old loud mechanical ringers of these old phones...and it works with this system, including the ability to dial out. There's also another ulterior motive for the vintage telephones working on this....in my pool room mancave, I want to find & restore a ~1940's wooden phone booth, it would be even cooler if the old telephone in it is usable....anyway, back to the project! Programming this thing is kind of tricky, it's all done through the 'master phone', which was included....so I just programmed the basics and will toil away at the rest later.....for example, which extensions ring or don't ring with an incoming call, etc.



Now the beginning of the install....in the secret room deep in the bowels of the building....

Control box on the wall...


The 'straight talk' box next to it.


Mockup is up & running!


That was all the easy part.....the real fun lies ahead, wiring the building for all this!! ...so yea, this will be an ongoing project!
