With the G2/G4, sending the page is as simple as sending a 2-tone page. The Dispatcher will select the appropriate icon and when they send the page the system will send out the pre-programmed TGID. The Dispatcher can choose to send an Alerting tone like they do for portable radios or not. Once the TGID is sent the Dispatcher can begin sending the voice message. With the G3/G5, no dispatching changes are required. Agencies can continue receiving their 2-tone calls exactly as before, but gain the ability to also monitor incoming P25 transmissions.
