In nonpersistentmode, the 4-wire call signal displayed on the panel matches the duration of thelogic-input closure, plus the time set for tally hold up. For example if a logic input is appliedfor 5 seconds and the tally hold up is set to 2000 (2 seconds) then the 4 wire call durationdisplayed on the panel LED will be 7 seconds.In persistent mode, the logic input triggering the 4-wire call is latched within PathFinder andthe corresponding tally is also latched until the call is answered.20.6.3 Twinklers ActiveTurns on twinklers at all times.Trilogy Communications LimitedIssue 1Page 127 of 127
