Panasonic 308/616 Telephone sets & PBX Compatibility

[Fabius]

I just bought off of eBay 8 telephone sets for the 308 & 616 systems. Also includes the user system manual. From the picture I can see that 3 have the read out and the other 5 don't. Total cost, which includes shipping, was $34. I already have a set for programming so I'll only keep one or two of the station sets. I'll keep the system manual and a station set manual. Everything else I'll sell at a very reasonable price. Once I receive the items I'll test them and post in the For Sale section.

I could be wrong....
   But I don't think any of these work on a KX-T308(10) or 616.   These are digital phones, while the 308 and 616 ESS require analog proprietary phones.

Not all LCD phones can be used for programming, either.
Also, the DSS (direct station select) feature is only available on 308 and 616 systems with a special firmware upgrade, which most systems we find probably won't have.

More specifically you need to look for Panasonic "Hybrid System" phones, as they have digital signals over Pair 2 and Analogue voice signals over Pair 1...

Hmm... I don't think that is correct either.  These are not what Panasonic called "hybrid" systems. There was a later series they called "hybrid", before the digital systems.

Technically no, the 616 and 308 aren't officially called Hybrid systems, but if a Panasonic phone has Hybrid System printed on it it's more than likely that it'll work, so long as it's a 2-pair line cable (some I believe have 3 pairs, which don't work)...

What model number is that a picture of?  A KX-T7030 ?

Looking at my manual collection...  you may be right.  The first "hybrid" labeled systems were the KX-TA series, and while those had a new line of telephones (T-7700), the T-7000 phones could still be used with them, as could the T-7300 series.   The KX-T7000 phones were upwardly compatible still with the KX-T30810 and KX-T61610 ESS.  So, it may well be that at least some "hybrid" series phones, may provide some compatibility with the 308 and 616s.

That's my KX-T7130E, bought as a potential lemon as the seller couldn't test it, but works nicely...

Ah...  the 7130 seems pretty much like the 7030, not sure exactly what the difference is.

As a summary, what I can gather:

The red high-lighted units are what most collectors are talking about:  KX-T30810 and KX-T61610

KX-T series PBX (206, 308, 336, 616, 1232),
KX-Txxx10 series PBX (30810, 61610, 123210): analog with digitally controlled proprietary analog phones (PT), and standard single line analog telephone (SLT).
  Telephones: PT:
                     KX-T30820, KX-T30830 (pgrm), KX-T30850    (3 CO)

                     KX-123220, KX-T123230 (pgrm), KX-T123250   (12 CO)
                     KX-T7000 series (7020, 30, 50)  (12 CO)
                     KX-T7130    (12 CO, additional feature buttons w/r/t the 7030)
                     SLT (TT, DP/LD)

KX-TD series PBX (308, 500, 816, 1232): "Digital Super Hybrid System"
Telephones: PT:  KX-T4000, T2000
                   T7000, T7130 .... ?
                   SLT (TT, DP/LD)

KX-TDA series

KX-TDE series

KX-NCP series

DBS series

Some telephones used six-conductor wiring, such as the KX-T123230D. These, with the suffix D, cannot be used on the four-wire systems.

Less buttons by the looks of things:

I sent a message to the seller asking him to check for a model number on the phones. Notice that the manuals state they are for the "small digital business system 308/616" though none of the phones being sold exactly match the picture on the manuals.

[unbeldi]

I'll check with the seller. He had stated these would work with the 308/616 systems.

That may depend on which series of 308, 616 system.  See my summary earlier...
... but I am not sure that there was a 308 or 616 in the KX-TD series, so he may have advised you wrongly indeed.  I think your phones are KX-TD series, do you know the model numbers?

OTOH, I see that the KX-TD816/1232 systems do accept T7000 series phones, so perhaps there is some compatibility somewhere.

I think, this is another completely different line of systems, the  DBS line, ''Digital Business System", which were 1990s systems.  I would be surprised if they work on our kind of 308/616s.

Panasonic made such a vast array of systems, it's hard to keep track of all in retrospect.  Fortunately many manuals are online, sometimes just hard to find. One must take the time to research the compatibility.

It seems that the best, or "safest", phones to get, are probably the KX-T7030... or KX-T7130, but the extra buttons are probably rarely needed.
These have 12 CO line buttons, more than needed for the 308 or 616, but not needed at all for programming.  I have a KX-T30830—these are actually kind of hard to find these days—with only 3 CO line buttons and only 8 station buttons, which is a limitation when used on the 616, but work fine for programming.

I think you are correct. The seller responded that one of the telephones is marked model VB-42210, which a Google search shows to be for the newer systems.  Luckily the seller offered a full refund.

Thanks everyone for the information. I learned a lot.

Got my refund. I bought a Panasonic KX-T7030 which I should be able to program with? The seller has one more available in case anyone is interested.
