Summary: I got mail...

I'd like to summarize what I've learned from all those great replies.

I will probably be using 8 (FG is unneeded, some pointed out).  I
want to use cables for both DTE's and DCE's, so the modem control
is important.

I got 14 replies, nearly all of which suggested Mod-Tap (manufactured 
by Darlabs, Inc. 800 252-1100).  In California, a firm called Nevada 
Western seems also to be popular.  Apparently these companies are not 
consistent in their assignments of the 6 (8) wires.

One of the messages gave me an idea.  We have 25-pair telco cable in 
each office left over from a previous phone system.  We should be using 
only 3 or 4 pair for our new phone system, so I will probably use the 
remaining 40 wires to supply up to 5 8-line RS-232 lines.  The only hitch 
on this is physical access to the phone cabinet, but the advantages are 
so significant that I'll find a way around this.

Thanks for all the help...
