This read-only Integer32 (50..200), in milliseconds, reports the cadence time used for CAS signals on this line, applicable only to CAS backhaul applications. This line-wide cadence setting underlies the per-DS0 on/off timing objects, giving an admin visibility into the base timing used for CAS signal generation on backhaul-configured lines. For example, an admin verifying why individual DS0 cadence values seem inconsistent with expectations might check vismCadenceTime to confirm the line-level cadence baseline itself.
