Hello,
     I am trying to set up DTS on an analog line in a 3300.  It has release level 7.0 SP1 PR1 and software load 13.0.1.28.  The analog trunk that I would like to use does not have the DTS service number set.  When I attempt to make the change it does not hold and does not appear to give me any type of error.  I did try and busy out the trunk and make the change, but this also did not take.  I am thinking the trunk is linked or something else along the way of busying out the trunk.  
     Any suggestions would be greatly appreciated.
Thank you,
Mark
