ISDN PRI interface LED

I have a network module of E1/ISDN PRI.

When I boot my router , i found that the LED signal for the CARRIER DETECT is on immediately.But there is no ISDN PRI connection connected to the interface.Is this is a hardware error ?

Re: ISDN PRI interface LED

The LED should not be lit, but I would still

verify if the DDR is operating as expected; it

may be that things will still work fine.
