3U Traffic Outstation Handbook

In addition a means of logging ALOTPV over a configurable period of time is
supported. This logged data can then be retrieved from the outstation and used by
the instation for traffic analysis and reporting.
The instation provides the means of setting thresholds and logging criteria for
ALOTPV and communicating them to the outstation via the normal configuration data
file. Additionally it is anticipated that different thresholds will be required for different
times of the day, days of the week or special occasions. To enable this requirement
a maximum of eight sets of thresholds is provided for each input.
A number of new handset commands have been incorporated in the firmware to
assist in field maintenance and fault diagnostics. These are covered in more detail in
the handset section, The new three letter acronyms are:-
CODE DESCRIPTION AND REMARKS
RTS
Raid Threshold Set in current use.
RLO
RAID ALOTPV – current value of ALOTPV n
RTG
RAID ATGBV – current value of ATGBV n (future implementation)
ROT
RAID ALOTPV Threshold – threshold for ALOTPV[n][Threshold Set]
RGT
RAID ATGBV Threshold – threshold for ATGBV[n][Threshold Set]
(future implementation)
ROH
RAID ALOTPV High – Shows 16 ALOTPV detectors, 1 indicates that
the ALOTPV was above the high threshold during the last averaging
period.
RGL
RAID ATGBV Low – Shows 16 ATGBV detectors, 1 indicates that the
ATGBV was below the low threshold during the last averaging period.
(future implementation)
RAP
RAID Averaging Period – Time in seconds over which RAID
measurements are calculated.
REN
RAID Enabled – check if RAID license enabled. 0 = disabled, 255 =
enabled
The RAID facility requires the use of an STCL supplied licence code in order to
be activated. The licence code is based on the OMU telephone number and is
downloaded as part of the RAID configuration data from an RMS instation.
U
3U unit firmware
RAID Facility : PB680 issue 20 or later
