SDI failed to enable pack because signalling process was missing
The signalling process specified in the parameters was not active when an attempt to enable a pack using that signalling process was attempted.
Check that all signalling processes required for your configuration are active and also 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 are using an Exchange Data Link Signalling process to gather additional call information, you might want to allow the trunk enable if the signalling process is missing, and to default to a different application profile. If so, change the setting of "Trunk Interlock - EDL" parameter (in the Trunk Interface Group) to DISABLED. The trunk will then be enabled.
