This problem has been bugging me for the last few days. I cannot seem to get the physical layer up for the connection between the DB-15 presentation on the E1 card on my 7206VXR and my BlackBox G.703 converter on RJ-48C.
I have tried various pinouts and am now losing my rag with it. I can get my line working on an 8-port port adapter card but not this card.
The following is my config on the serial interface:
interface serial 1/0
clock source internal
If anyone could suggest anything I would be eternally grateful.
