IQ Link displaysseveral read-only NTCIP Objects. These read-only NTCIP Objects are displayed in IQLink only to show the capacity (i.e. maxOverlaps, maxPhases).NTCIP Object 2.5.5 maxPatterns specifies Pattern 253 as the maximum possibleCoordination value. The ATC-1000 has 48 Phase-based Patterns denoted 1 thru 48, asshown in the Coordination Window’s Pattern Table. Patterns 49-253 are for pre-timedoperation or reserved for future use and not relevant to this Phase-based Coordinationchapter.NTCIP Object 2.5.5, states that the Maximum Patterns Parameter is the maximumnumber of Patterns this Actuated Controller Unit (ATC-1000) supports. This objectindicates how many rows are in the patternTable object (254 and 255 are defined asnon-pattern status for Free and Flash).218 ATC-1000 Advanced Traffic Controller
