DSL-G624T Wireless ADSL Router User Guide
Cell Delay Variation Tolerance – CDVT is a measure of the cell clumping
phenomenon by which cells are delayed in the network and are
clumped together and arrive at a system at a faster rate than negotiated.
Increasing the CDVT creates greater bucket depth.
CDVT
Maximum Burst Size – The MBS is the maximum number of bytes that can
be sent continuously from the source to the destination dropping any
packets. Some ATM providers set the MBS and CDVT very low and adjust

As with the PVC setting, this is mainly for use by clients who are configuring
the Router for multiple virtual connections. Use this to enable or disable the
PVC you are currently configuring. By default, the Pvc0 is
