13.4 Rebroadcasting Post-Train Messages
The Rebroadcast Time Limit option on the Messages submenu defines the amount of time
that, following a train passing over the site, its post-train (that is, end-of-train) announcements
are available for rebroadcast. To request a rebroadcast of the last train a 2300-356 DTMF
Decoder board must be installed and working properly.
Following train passage, recorded post-train announcements are available for rebroadcast
until the time period defined by the
Rebroadcast Time Limit option expires. Recorded
messages are available indefinitely if this value is zero.
When rebroadcasting a recorded post-train announcement, the format used is:
Rebroadcast
(train messages) [ancillary messages]
Rebroadcast
Detector Out
For example, if the No Defects option on the Messages submenu is set to 2 and neither an
Exception Alarm nor an Integrity Failure is detected on the last train, the format of the
rebroadcast message is:
Rebroadcast
U-P Detector Milepost (mile) [track indicator] No Defects
(3-second pause)
U-P Detector Milepost (mile) [track indicator] No Defects [ancillary messages]
Rebroadcast
Detector Out
