This attribute specifies the maximum time that a cell may arrive
late, compared to a nominal time established at buffer initialization,
without producing errors on the service interface. The nominal time
of a cell's arrival is predicted according to the time interval required
to transmit a cell's worth of data on the service interface.
This attribute's value is the delay that the Cell Delay Variation
Tolerance buffer adds to the egress stream immediately after the
buffer initializes. The buffer absorbs variation in the arrival time of
cells from the network, so that a steady stream of data appears on
the service interface. If the buffer underflows, due to a late cell, fill-
in data is output on the service interface while the buffer re-
initializes. When the buffer has re-initialized, normal data is output
on the service interface and the delay in the buffer is restored to the
value of this attribute.
This attribute must have a value lower than a numeric value of
maximumBufferDelay. The relationship between this attribute and
bufferSize is described under that attribute.
Setting this attribute too low allows traffic with normal CDV to
cause unnecessary loss of data on the service interface. Setting this
attribute too high imposes an unnecessarily high propagation delay
on the egress stream.
On MSA cards this attribute's provisionable range is 0.01..32ms and
the value applied is rounded up to the nearest multiple of 0.125ms.
On 4pDS1Aal1 and 4pE1Aal1 cards, this attribute's provisionable
range is strongly dependent on the bandwidth of the channel, and
the value applied is rounded up to the nearest whole number of
milliseconds, then rounded down to the equivalent number of cells.
