Is my TE210P Card Working?

It says on the Digium website that if the TE210P card is working there should be some activity on the card itself. It should be flashing red. However, when installed for E1 standard no light activity is seen. With or without the zaptel modules being loaded. If I change the jumpers to set it for T1 then the lights are active. I don’t have the option of putting an ISDN line in to test as this card is on a backup server. What are the best ways to test the card itself to make sure it’s working?

Many Thanks.
