Hi I hope someone can help

Kxtd1232 master cab
2x 8 extn modules
1x pri isdn module

Slave cab
Is using 15 extns

My customer has a 1232 master and slave cab system. All extensions (more noticeable on analogue) have a background whine.
I have changed the master cab and cards but still have the same problem. If I disconnect any cards on the system the noise goes away, as soon as you connect it comes back!
If I disconnect the slave cab it makes no difference.

Can someone please help I am stuck!!!

So if disconnect the PRI card the noise goes away? If you reconnect that it comes back? But if you disconnect one of the extn modules it goes away as well?

Probably a bad main cabinet. We just replaced a main cabinet that had the same type of noise. Replacing it fixed it. Panasonic used to make their products last for a long time, but not forever.

It could be picking up noise from external source
try disconnecting one module at a time and then each extension on that module
