This read-create Integer32, in seconds from 0 to 100, specifies how long continuity test tone 2 plays unless interrupted, with 0 meaning indefinite generation, serving as the second stage of a two-tone continuity verification alongside cxeCcProfileCot1Timeout. Admins care because both continuity tones must complete properly for the trunk to be certified as continuous end-to-end. For example, an admin seeing continuity test failures only on the second tone would specifically check this timeout rather than the cot1 setting.
