Yeah, it's been a while. I do remember those Goldstar flat pack KSUs having some kind of issue with polarity reversal on the second pair. Maybe it knocked out the paired station if reversed? I can't say for sure.

Re-hashing OLD thread about OLD phone system... but wasn't Northcom taking over/ merged with Intertel ??
I saw an old manual of theirs and they had a "Premiere" system and it's font was EXACTLY like Intertel's old Premiere system....

It's also interesting is looking at the cover page. June 1984 the Northcom Premier NC-1648 and the Feb 1985 Northcom 1A3. The Premier is digital while the other is electronic.

North, and Northcom were products produced for the distribution unit of the United Telephone System. This company was called North Supply, later becoming Sprint/North Supply, then Embarq Logistics and finally KPG Logistics. All of these systems came from the same manufacturers, with the majority being Lucky Goldstar, later LG Electronics. They made systems marketed under many, many different name brands. The documentation similarities are because they were printed by the same source and just altered with the different brands' logos.

They didn't make systems for Inter-Tel or Mitel though.

Ah, the NC-1648. The second radio station I worked for installed one in 1985. I think I still remember the password to get into the setup menu. No one wanted the system when it was replaced, so it got scrapped.

Got replaced with a MICS about 15 years later (the MICS is still in service).

Professor Shadow...THAT'S THE MANUAL I WAS REFERENCING ..the name and font is INDENTICAL as stated in my initial post ---here is a "INTERTEL Premier" power supply.... these Intertel Premiere systems were almost identical to the Intertel GMX48...and had same power supplies...
Notice Premier font is IDENTICAL to Prof Shadow's pictured Northcom manual "Premier" .
I know this isn't critical stuff but just NEED CLOSURE! grin
Hence, once again why I thought the two companies merged / were affiliated.

That power supply is for an ESP Premier 1224 / 2460. It was made by Intertel with North Supply's name on it. Nice system, 3-pair wiring, and don't even look cross-eyed at the blue pair or you will pop a fuse and take out 4 stations.

Was it 4 stations? I was thinking it was the whole card. We took over an account where over the years some people would reverse the first pair on the backboard while others reversed at the jack locations.

Carry extra fuses!

It's been so long, I just googled it. 6 stations per card!! (hazy memory had 8) And yes, only one fuse for the whole card.

I started carrying a pair of fiberglass long nose pliers for bridge clips on the blocks, and a fuse insertion tool to replace the fuses without pulling the board.

Yeah, had to pound into the guys to terminate the jacks normally and reverse the jumper at the backboard, so didn't have to think about if it was an amphenol to modular adapter at the end of an old 25 pair run or a 3 pair cable on a jack.
