Turn off permanent key mode 3

I am trying to reprogram a Merlin Legend 7 system from key mode to hybrid, but the system beeps when I try to change it. I pulled the controller module out, and it appears the switches are set to put it in permanent key mode. Can I just move the switches back to the other position so I can change the mode to hybrid? How "permanent" is permanent key mode? Changing the switches won't permanently disable the system or anything will it? Thanks.
 
Changing the switches or jumpers will allow you the option of changing the mode in programming.


If is because of the FCC's sual registration. Lines used to be tariffed differently for Key systems and PBXs. It is irrelevant today

Thanks for the reply, and for the explanation of why that option even exists. I had a feeling the whole FCC registration part might be irrelevant these days, but was hesitant to flip the switches without knowing for sure what might happen.
 
Lay the processor card down with the edge connector to your right and the component side of the board facing you. The plastic part of the blade will be on your left.

At the middle of the board and on the right hand side (just above the edge connnector) are two DIP switches. Both switches should be in the up (open) position.

Everything else on the board is essentially a jumper. These jumpers consist of three pins...most of which will have the middle and right pins bridged (provided that the proc card is still oriented the same way).

There is one exception, however. In the middle of the board about 3½ inches from the bottom, you'll find the last jumper. DO NOT bridge the middle and rightmost pins, but instead leave the jumper hanging on the right pin only OR remove it all together.

Oh, and no ill effects either. As Tom pointed out, this ability was added on purpose and was meant to be changeable.

I doubt that the switch and jumper settings mentioned here are available anywhere else publically, so get it while you can.

I know the old FCC registration program had some unusual stuff in it, but this is the oddest! And I'm sure the customer is going to allow an ILEC to take their equipment out of service to look at the config. and switches. They would not know a Legend from a bat handle!!

This falls in the same class as having to file an affidavit for CSUs connected to DS1 service! The companies where I worked never did any of that nonsense!

Anything to appease old Ma Bell, and the "new one" is as cunning and greedy as ever!

Well, that was not a "MA BELL" thing as you would like to blame.

It was a TARIFF issue imposed by some of the STATES.

They wanted to charge more for "TRUNKS" to a PBX and less for a line to a KEY System.

Thus, we had to create a HARDWARE fix to accommodate this requirement.

Certainly the Operating Companies had a hand in getting the TARIFF written.




 
That may be true, but the tariffs did not apply to any CPE systems, since the customer owns the equipment and could order any type of service! Although the operating companies may have had other ideas, it was the operating companies that wrote the tariffs. The PUCs never wrote any tariffs.

At one time (1970 - 1980s) "trunks" (TMB/TM2) were cheaper than 1ML/1MB business lines in California Pacific Bell area. Since they were usually designed with a VFR, the transmission level was between -3.0dB and -4.0dB loss, unless you were on a short loop close to the CO. But then that changed and CPE systems became multi-functional rather than just a key system or PBX. Rates had changed and some folks did not want to pay for trunks. The other part had to do with the FCC registration code of the system or hardware.

Some of the BOCs were easier to deal with than others. Really all you had to do is give them the "right" registration code when ordering service. But that is very moot these days. But some of the effects linger.

It is interesting, now that I think about it that the AT&T/LUCENT/AVAYA stuff is the only manufacturer that did anything like this on a system. Does anyone know of any others that did this?

Ah, the good old days...can you even order a "ground start"
trk anymore?? Haven't seen one in years...
 
Ground-Start is still very orderable on a trunk or 1ML.

Some very old timers may remember before the Dialtone-First payphones all Bell System payphone lines were Ground-Start.

....JIM....
 
Hey ... whatta U mean Old Timers!! O no, I fit into that.
Ground start goes on .. I've had to deal with some Ground-start DID trunks in the last nine months., that was a memory from the past. In the 70's & early 80's we had to report all kinds of things being connected to "Their" network...
...and "what is the Ringer equivelence of the automatic dialer you want to connect to your 565 set"

I believe most of the WECO 100 series Coin Collectors has a wooden terminal strip on the lower housing backplate. The 200 series used a spring pileup contact arrangement of sorts to make connection with the upper housing. They are shown in the old BSP 506 division.

What..are the antiques coming out of the closet?
I don't think auto-dialers that attach to a rotary dial
565 key sey or a 2565 tt set had ringers...
If memory serves the 6 button autodialer was a 2650 type
set...its been a long time since I seen one.
 
Yes, the WECO 2662 was the TT 6-button Card Dialer set. I have one of the rotary dial versions the 662, and one of the special 16-button TT type 6-button, the 3666A1, but it doesn't have a housing. It is the one used with the Autovon network.
