Another day with no work assigned, which means I get to go the the 2.1 and find dial tones that are not going anywhere so I may issue disconnect orders. Said orders to appear weeks later on my workload showing that I have things to do when I don't. Great system there.
Anyhow.....
Not all wire is created equal. The cross connect wire for dial tone is normally a single red-white pair. Key Telephone use three pairs, usually blue, orange, green. Data was generally connected using a two-pair red-green-orange-brown jumper, which is no longer used as data has been superceded by patched LAN connections. So there's these red-green-orange-brown jumpers on my tie cable to the 1.1 -- three doubles for 8-wire connections. We used that arrangement for serial printers off the Ungermann-Bass Access One.
The Ungermann-Bass went in in the late 1980's - early 1990's. That was the system I replaced with the Cabletron upgrade in 1996. Since the system has been gone for over a decade it should be safe to pull the jumpers. But.... I can't pull until I verify that at least one end is hanging in the breeze. So I follow note what tie pairs and head for the 1.1.
I was expecting either no cross connnects, or cross connects to the Access One Room (which is now housing the ISDN equipment.) I was wrong. My tie pairs were connected to Inside Wire. Not only that, but two pairs at a time, not four. Nah.... couldn't. Outside the 1.1 terminal room is the "printer room" which is now a storeroom. The printers that were in it were replaced when the Access One went *IN*. Those printers were connected to a 4540 controller, SSI, super antique. Open the floor in the Printer room, lots of chopped off IW. Close, open the terminal room floor next to where my jumpers are tied on the IWs, tug one, out it comes.
So I was wrong about them going to the Acccess One and being unused since 1996.
The jumpers have been unused since about 1992.
Finally got the disconnects completed.
