Cisco 3660 Router E1 Controller Error

Hi Collegues,

I have 2 Cisco Routers 3660 with 2 E1 Controllers each connected to MD110 PABX. The problem is the MD110 is blocking the call and the alarm code in MD110 Alarm 303 (Data Link Alarm). Is there anyone experiencing the same problem what I have. Please advised.

Thanks

2. Cable Parametrs

3. E1 Parametrs like line coding and so on
