Telephone guys? I have the insides of a AC273 (?) cabinet used with the
LBXD TD. It can have a shelf that allows 2 TDs to be mounted.
See below the pictures for the actual question. All other comments are
designed to trigger memory of those that might have an odd drawing lying
around that fits.
I have the above parts with cables and connectors attached.
I'm about to trace the wiring to make a drawing.
I think I have figured out the numbering scheme here after considering
that it was originally designed for telephone MDF use. Am I correct in
assuming that starting with the 1 at the right end, you call the first
pair of terminals pair #1, then number going down to pair #6, then start
pair #7 back at the top. It appears that Teletype only used the right
terminal of each pair.
There are 2 cables that come in from the TD connectors (one for a LBXD
base and the other for a 14 TD base) and 2 that go out into 32 pin
ribbon connectors. Then there's a power cable and a couple of cable
that might be signal lines.
