Description: This attribute specifies the maximum delay that a Cell Delay Variation buffer is permitted to add to the egress stream. The delay in the buffer is modified in response to variation in the egress cell stream. At the point that the delay would be modified in excess of the maximum, sufficient data is discarded that the delay returns to cellDelayVariationTolerance.

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 permits the buffer to introduce an unnecessarily high propagation delay.

If this attribute is autoConfigure, the maximum delay tolerated in the buffer is two times cellDelayVariationTolerance. On MSA cards, 'best-effort' applies on a channel with high cellDelayVariationTolerance and low ATM bandwidth. The value applied is the same as the range limit on provisioned maximumBufferDelay on that channel.

On MSA cards this attribute's value is rounded up to the nearest multiple of 0.125ms when applied to the buffer. The range is nominally 0.12..63.62ms, but the upper limit may be reduced by up to 6ms one a channel with high cellDelayVariationTolerance and low ATM bandwidth.

On 4pDS1Aal1 and 4pE1Aal1 cards this attribute's value is rounded up to the nearest multiple of 1ms when applied to the buffer. The upper limit is roughly inverse- proportional to the ATM bandwidth of the channel.
