Programmer
I am trying to set up a Q931 link between two Option 11s one running 25.40 and the other release 4. I have done this many times in the past but not for quite and while and have run into problems and wondered whether anyone can help.
I have the programming done and two systems connected on my bench with two coax cables. When all is done and they are connected i get oos and red alarm showing at each end. If I disconnect the cables or cross them over it has no effect on the LEDs on the cards. I can set the clock and it locks to the slot which is weird gievn the red alarm each end and both cards showing oos.
I wondered whether it was a problem with a CPU and swapped one one of them but that made no difference. I swapped the coax cables but that didn't help. I moved the PRI card (I'm using a NTBK79 at each end) to a different slot and that didn't help. I am waiting for another PRI card to be dropped off in case one of them is faulty but other than that I am out of ideas.
It could be programming although I have followed the 2Mb PRI implementation guide on the NTPs so it should be OK but you never know.
anyone got any thoughts??
