Pack enablement failed

SDI received an error from ioctl call to enable the pack. This may be caused by invalid parameters for the pack. The reason for the failure is given in the `Information' field.

Sometimes after pack configuring a partial CAS protocol trunk (a T1 trunk with less than 24 channels or E1 trunk with less than 30 channels) the red alarm 27010 (Pack enablement failed) occurs when Blueworx Voice Response is started and the trunk enabled. Whole trunks on the same system can be enabled without this error.

First time through, not all channels of a partially configured trunk are initializd properly. Unused channels (those not included in the partial trunk channel group configuration) can give rise to a 27010 error (Pack enablement failed / channel group is not initialized for channel). This device driver error occurs because of the need to initialize all channels in a trunk for signalling even though all are not included in the channel group.

Check the settings of parameters in the Trunk Interface, Signalling Type, and Channel Group parameter groups for this pack. It may be useful to check the errno value against those in /usr/include/sys/errno.h. If the information field says that files are missing, corrupt, or cannot be opened, check that the files exist and that read permissions are set.

To avoid the partially configured trunk problem:

  1. Reconfigure the trunk (Configuration -> Pack Configuration -> Change) to include ALL channels of the trunk in the channel group.
  2. Save the configuration and shut down Blueworx Voice Response (DT_shutdown).
  3. Restart Blueworx Voice Response and change the pack configuration back to the desired partial trunk configuration. On restart the 27010 error should now be avoided since the unused channels of the partial trunk are correctly initialized.
