VIC3-4FXS/DID DSP Alarms upon PBX DID Port connection

I have done an integration between VIC3-4FXS/DID card with Meril Legend DID Card. I see alarms when the DID port of Legend PBX is connected to the FXS port. I used Loopstart for signaling while PBX used Immediate start signaling on DID. Provided the status of the FXS port as well. I kept at 600 ohms impedence

If all works, you can ignore these as they are purely cosmetic.

Otherwise, try updating IOS.
