UC500 FXS Ports without tone

Hi, I have a uc500 my problem is:

The 4 ports FXS is dead, I don't have a tone signal, ring tone, etc.

I review the status of port 0/0/0:

show voice port 0/0/0

Foreign Exchange Station 0/0/0 Slot is 0, Sub-unit is 0, Port is 0
Type of VoicePort is FXS  VIC3-4FXS/DID
Operation State is DORMANT
Administrative State is UP
The Last Interface Down Failure Cause is Administrative Shutdown
Description is not set
Noise Regeneration is enabled
Non Linear Processing is enabled
Non Linear Mute is disabled

the port apparently is ok, but It does not work.


Re: UC500 FXS Ports without tone

Hello Rene,

You should contact TAC most likely they will need to replace the full UC520 if the ports that are not working are the built in ports.
