GW/ALARM>

* If you see constantly increasing slips in alarm, you have to check clock configuration

(Master/Slave) in PBX. Otherwise, make sure that your connecting cable is working properly. As you

can see above, it is normal to see one slip in a fresh boot.

* You have to check frame mode in digital trunk configuration when CSOOS alarms are increasing

without a slip. For instance, you can see CSOOS alarms increasing without a slip if GW uses CRC4

and PBX uses NOCRC4.
