SDI detected missing non-essential signalling process during enable
The signalling process specified in the parameters was not active when an attempt was made to enable a pack using that signalling process. The pack has been enabled because the "Trunk Interlock - EDL" system parameter (in the Trunk Interface Group) is set to DISABLED.
Check that all signalling processes required for your configuration are active and that the Signalling Process Type parameter in the Channel Group definition is correct. This message is repeated for each missing signalling process type. If you want to fail attempts to enable the trunk when the Exchange Data Link process is missing, change the setting of the "Trunk Interlock - EDL" system parameter to ENABLED. The trunk will then not be enabled.
