The only way to know for sure which CC is the primary and which are alts is to run Universal Trunker, or T-88 on the system now and monitor the results. Now that they have not only rebanded but upgraded the system's performance, it is good for many more years. Just a year and half ago when Lee Co was asking about the MSWIN, they wanted to desperately get on it as the Lee Co trs is one of the oldest in MS, and was beginning to show signs of failure de to old age, especially on the output on one of the sites. Now it has new life. The oldest systems in the state are the original City of Hattiesburg (Now grown into the Forest Co TRS), The City of Tupelo, and Lee County (Now run entirely by the County), City of Vicksburg (Now merged with the Warren Co TRS), City of Jackson (Now grown in with three other systems to form the CMSRTRS), City of Madison (Merged with the CMSRTRS), and the two State of Mississippi systems *MSU/Starkeville* and *MDOC*.
