Southest operates on Southern Disp1/2. The Southeast talkgroup, as well as the North City West and Northeast talkgroups, are not used, because the city doesn't have the budget for staffing the dispatchers for them 24/7. NCW/ N/E, and S/E, are used as sort of backup dispatches for downtown events or when there is a very major incident expected to tie up a main dispatch for a day or so. Sou and S/E operate on Sou, Nor and NCW operate on Nor, and Eas and N/E operate on Eas.
