I have a NEC ND4E Digital Channel Bank which is set up between my PBX and a microwave tie line. I recently moved it's location and redid all the wiring as part of this, but carefully traced everything so it was re-wired exactly the same way. HOWEVER it doesn't work any more and every phone call just gets dead air. I have triple and quadruple checked my wiring and I would swear it is correct. There are no alarms or anything. However no calls go through. Anyone know where I can get a manual or anyone know about starting these up, if there is a sequence to be followed or code to enter or anything? Thanks.
