Does anyone have a datasheet for a Tellabs 82.4447?

This is a telephone central office piece of equipment but it's being used in a radio network for cross connecting base stations.

I can guess at the pinouts, but need more information.

Any CO guys out there have this data?

This is a data bridge. The part #, at least for me, does not reference.
I have access to Tellabs database. There are references to this being a discontinued unit.
Sounds like what was called a type 400 unit. These were apx 5"x5", some what square circuit pack.
Typically mounted in a card cage, or in a small wall wall mount unit.
Much like a Smart Jack for T1 service.

In the older designes for 2 and / or 4 wire VF circuits, these were typically used as a test access unit at the far end.
The C.O. tester could loop the unit with a 2713 tone and test for faults.

Hope this is what ya need. Sorry I can't get the Issue sheets.

( yes, I'm a C.O. guy )

Thanks for the reply, Bat Man.

I have access to the Tellabs Portal and it's not listed. I did get the datasheet for installation and had to go to a used equipment house to do it. Tellabs does not have this and other docs in the Portal. I offered a .pdf to them to post and they have not replied.

This is for an old data circuit and it doesn't have loopup/down capability. In fact, it's a pretty dumb board.

Just another one of the things I find myself involved with.
