I was trying to put in a cross connect for a ds0 in a Titan 532L, but was having no luck as I didn't have a Waddel cheat sheet.. I was putting a dacs II type command like
TCON::FROM 15602,TO 15602,TRSP, MUX
but had no joy, yielding an obtuse error message. So after bang my head against my desk and getting help from two co-workers I finally googled the machine and found "Chris Deputy's" page on Comcast with a command saying to loopback the ds0, but I knew it was actually to put in the cross-connect. Sure enough
TCON::FROM 15602,TO 15602,TRSP
is all it took.
