LD 30 can be removed:
LD 17
Req: CHG
Type: OVLY
Drol: x30
Ld 30 is recommended in the midnight routines for 61 trough 81. This route also tests memory of each enabled network card, Test speach path for each enabled PE shelf, Signaling path for each line or trunk card, switches clock controllers.
I recommend the previous sudgestion - build a dummy acd.
