No longer exists. IDPSC no longer uses individual QC Tones. Its all automated through a digital data stream on the TRS now. You hear an audible alarm tone sequence for Station Alerting Testing at 0700/0800 but its the same set for all. You hear a pair of tones for every "tone out", but they are the same pair for all users as far as the audio goes. All other paged information is done over data pagers, or the MDT's/Laptops. The old fashioned Quick Call stuff is long gone here. And other than when the CAD system is having a fit, or goes down, or they are running Dispatch/Control training or special messaging, all aural dispatching is pure Locution Automated Digital Voice now.
