[cisco-voip] Slip secs on E1 interface(urgent help please!!!)

[Jason Aarons (US)]

Did you put a hardware loop past the smartjack that they ran to? If they
run a loop to you do you run clean?  

 

I've seen tests to SmartJack pass, but then to loopback plug past the
SmartJack fail. One time the wiring on a SmartJack was wrong pins but
yet it passed all tests as clean but had serious problems.

 

Make them replace the SmartJack even if tests pass.

Replace the VWIC2-MFT card.

Hi 
We got a E1 interface connected to a ISDN onramp-10 service. We
identified a lot of slip secs on the E1 interface which caused the fax
fails.< network-clock-participate wic 1>  and <network-clock-select 1 E1
0/1/0> commands are already configured on the voice gateway. Had the
carrier did a remote loopback test(they did the test without attending
the site, I don't know how they did the test) and they advised the
service is fine.
Any ideas what the problem would be?

Thanks a lot.
