Theory of Operation Loop Start Interfacing: The TAMB2 provides a 24V DC talk battery on its T (tip) and (in the case of talkback paging equipment).

10 Disconnection of R (ring) terminals. When it detects a DC loop current flow the page happens when the loop start trunk goes on hook and through these terminals, it will activate. Upon activation, it will loop current flow stops. In this mode, the TAMB2 responds to produce an announcement tone and connect in the paging the status of the loop current flow and generally no timers are amplifier through an isolation transformer. The announcement needed to control when it disconnects. However, a Trunk Timer tone can be set to be heard only at the paging phone or at both feature is provided that can help prevent accidental lock-up of the phone and over the paging system.
