20.4 READING CONTROLLER TIMERS
It is possible to read whether certain controller timers are active, held or expired, and
also what the count value is.
Following is a list of timers which have the above facility:
Minimum
Extension
Maximum
Delay
Sequence
Intergreen
2nd-ary Intergreen
Hurry Delay
Hurry Hold
Hurry Prevent
Conditioning
Call/Cancel
Priority Extension
Priority Maximum
Priority Inhibit
General
Compensation
Fixed
Window
Hold Intergreen Maximum
Hold Intergreen Extension
General/Sequence. These are timers which are not available to the traffic engineer but
are essential to the correct operation of the controller, e.g. start-up, data set ready,
handset timeout, background checks, start up switch to bright.
Note the timers cannot be loaded with a value in conditioning and the actual count
value cannot be read. Only logical expressions can be performed, i.e. count equal to ‘x’
or count greater than ‘x’.
