Installed a used BBCU1A/BECU1A into CHSUB672A cabinet.When I go off hook telephone has extremely loud volume on headset and or speaker. Removed all cards from cabinet except 1 PDKU2 which I rolled with other PDKU2's to see if the noise would go away.No difference when using telephone.Tried multiple phones no difference.Do I have a bad processor?
Also pdn's came up as 4 digits instead of 3 after initializing cabinet and defaulting processor. Where do set all PDN's to 3 digitits in programing?
Thanks
Shaun
