Anyway here goes again.
I have an MX controller with an AOB installed. The other day the analogue extensions died. There is nothing on the ports. I have swapped the TJF cable, replaced the 24 port patch panel, rebooted the controller, re-programmed the extensions and upgraded to ver 6. Non of what I've done are obvious ways of resolving this but I tried everything.
The trunks on the embedded ASU and AOB are fine.
As a last resort I thought that maybe the DSP (Telecom module in slot 4) might be faulty. So I replaced the DSP module. Having done this though the controller fails to boot and goes into a reboot sequence.
So there are two questions here,
1. anyone had this problem with dead analogue extensions on a MX 3300 controller and,
2. Why would the controller not boot with the new DSP module installed?
