MSU Voice and Signaling Proxy Interactions
The MSU handles interactions with a PSU voice or signaling proxy request from the DVR
based on the following general priority rules:
• MSU Emergency overrides all proxies including PSU emergency alarm /
emergency call.
• PSU Emergency overrides all MSU non-emergency proxies
• MSU PTT and signaling features (call alert, status etc) override all PSU non-
emergency proxies
• PSU non-emergency proxies override MSU receive
