No Ringing on ONS Cards

[WJ2600]

I have 4 Peripherals connected to a 3300 ICP, everything went smooth til i have noticed that some analog extensions prorammed in some ONS cards do ring when calling them, they can call out, they hear only one ring then keep quite,

nothing particular in the Logs?

Any Idea how to protect the other cards?

sounds like ring trip which normally is bad cabling.

It is not a new cabling, they worked before perfectly for long, and by the sudden it occured, it started in slot 9 then went to slot 10 i have no much spare cards to replace them,

It worked perfectly before is not a valid argument.

It is not working now. Did you try removing the jumper and test? If not, why not?

Thank you all for your help,

i will recheck again all the cabling from the TJF to the MDF,

we have a new technician, and may be a short circuit was made by a mistake,

thank you again,
