To change the transmit SCR for the default VC, complete the following tasks:
Setting the Default VC Transmit MBS
The transmit maximum burst size (MBS) specifies the maximum number of
sequential cells that the default VC can transmit at the peak cell rate before the VC
must relinquish bandwidth to other VCs. By default, the MBS is 40 cells.
However, you can set the MBS to any value from 1 to 65,535.
When you set the MBS, you should select a value larger than the largest packet
that the default VC can transmit (that is, the size of the Maximum AAL CPCS
Transmit SDU). For example, if your VC accepts packets that are less than 4,608
bytes long, set your MBS value from 45 to 50 cells.
