On 4pDS1Aal1 and 4pE1Aal1 cards, this attribute specifies the size
of the AAL1 receive segment reassembly buffer in bytes. On
initialization the buffer is filled to a level determined by
cellDelayVariationTolerance. Thereafter the buffer is emptied as
TDM frames are transmitted, and is filled as ATM cells are
received. If the buffer overflows, sufficient data is discarded to bring
the level down to that set after initialization. The cause of a buffer
overflow may be one or a combination of any of the following: cell-
arrival-jitter, initialization with delayed ATM cells, or TDM clock
difference or wander.
On 4pDS1Aal1 and 4pE1Aal1 cards, if this attribute is
autoConfigure, the buffer size applied is equivalent to two times
cellDelayVariationTolerance. A provisioned numeric value of
bufferSize must be higher than the equivalent
cellDelayVariationTolerance, plus an allowance of one ATM Cell
for the quantization of data in cells, and an allowance, if applicable,
for the ATM overheads of structured CES.
On MSA cards this attribute's value must be autoConfigure, to
acknowledge that maximumBufferDelay is provisioned instead of
this 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 permits the buffer to introduce an unnecessarily
high propagation delay.
