Dead air after switching loop and Dchannel to dual PRI Card 2

[ttdredd1]

Users say when they talk to a person they will randomly hear dead air for a second or so and then hear the caller again. It's as though they are losing signal for a sec and then comes back? The end caller can hear them fine without any dead air but they seem to get it without any warning, will just heard silence and then will hear the other person.

I have checked and the loop is experiencing some clock slips and we have re-set the counter but even when it's at .002 they still have same issue.

This is on an opt61c.

What could be the problem?

Your slips are coming from your primary. You need to look for issues that will effect your clocking on it, before you need to worry about the secondary.

Check your cables, Have you tried a loop back plug? Use a cross over cable and take your CSU out of the scenario... These are just a few things you can look at. Just isolate and break the circuit down.

No we only have a primary circuit over there?

I will look into the programming.

Blackbox programmed the card manually after switching it out.

Thanks again for all your help.
