Signaling Request Interactions with Voice and Signaling Proxy
When the DVR is in the process of handling a voice or signaling request for a PSU and
another Local PSU initiates a Signaling request, the DVRS will respond depending on its
programming and as described in Table 16 and Table 17 below. PSU Emergency Alarm
is considered High Priority Signaling. All other PSU signaling (such as Status, Message
etc.) is considered Low Priority.
