Explanation
The E911 subsystem generates log report E911204. The subsystem generates E911204 when a call disconnect timer expires. A call disconnect timer has the office parameter E911_PSAP_DISCONNECT_TIME. The system waits for the line appearance on a digital trunk (LTD) Public Safety Answering Point (PSAP) to go on-hook. The system activates the timer while it waits. The system also activates the timer if the LDT PSAP goes off-hook to originate a call.
