Problems with JPM2194A

Hi people

We have using a patch panel black box JPM2194A, with 8 FXS + 4 BRI (EVM-HD-8FXS/DID with EM-4BRI-NT/TE)

The 8 FXS is workss fine.

But the 4 BRI......NO.

All BRI ports with Polycom connected with appropriate cable are down, down(not connected).

Is there any jumping on BlackBox?

Thanks

Peterson

Re: Problems with JPM2194A

Which gateway are you using? The BRI ports need BRI cross over cable to connect to conventional user side devices
