when you are connected to the oam port, check to see if your pc resolves a ip address from the bcm dhcp server. if it doesn't, set your ip to static "10.10.11.2" then try to ping. if you get in check your service manager to see if some services have stopped. if they have you can try to restart them but Nortel warns all techs to consult a Nortel enginneer before doing so.
