If the hotspot is busy with another mode POCSAG messages will be stored until the other mode’s hang time ends and then the stored messages will be transmitted. Your hotspot will transmit POCSAG messages on a POCSAG frequency then change back to your regular hotspot frequency. POCSAG is an acronym for Post Office Code Standardization Advisory Group which developed the code for the British Post Office. See the DAPNET wiki for a basic overview of POCSAG. You can configure your Pi-Star hotspot to transmit these messages on the worldwide POCSAG frequency of 439.9875 MHz (or any other frequency you choose). POCSAG is a one-way pager protocol that is carried by DAPNET (Decentralized Amateur Paging Network) which was developed by German Amateurs.
