This read-create value, in microseconds, configures the Cell Delay Variation Tolerance (CDVT) used in the local-to-remote direction, where the maximum value tells the switch to use its own default CDVT. An admin sets this to define how much jitter, or cell arrival timing variation, the connection is expected to tolerate, which factors into the switch's traffic policing and conformance checking for that direction. For example, for traffic more tolerant of jitter, the admin might leave this at the default rather than manually tightening it, letting the switch apply its standard tolerance.
