The first generation of Adtran HDSL was a big improvement over conventional DSX1 spans but the older technology can get a little flakey at time… Since you
from within the bowls of the death star, I can’t directly help ya, but here’s what I’d do

Your SSC tester should be able to turn in a ticket (TFAS?) to your CPC requesting a redesign from the first generation HDSL to HDSL4. Doing it on an internal order (aka bureau CLO or aka B-CLO) should generate a PICS ticket to send new cards to the C.O. you’re working out of. I’m sure things have changed since I was there, I know the TFAS process has come along since I left their CPC.
