[asterisk-users] Problem E1 PRI

[Sebastian]

Hi,

I'm having problems with a new ISDN PRI in a new server.
The cable is connected and the E1 modem seems to have issues with 
syncing (blinking light on the modem).

versions: CentOS 6, asterisk 1.6.2.20, dahdi  2.5.0.1, libpri 1.4.12

Any ideas what could be the problem?
