84 CHAPTER 4: CONFIGURING PATHBUILDER S330/S310 MODULES, PORTS, AND APPLICATIONS
CAUTION: When assigning shapers for VCM circuits, be sure that the shapers are
wider than the bandwidth used for the voice traffic.
To configure the MCPU shapers, follow these steps:
1 From the MCPU Card menu, shown in Figure 52, select [2] Shaper Configuration
to display the MCPU Shaper screen, shown in Figure 53.
The MCPU Shaper screen consists of a table listing the current shaper values in
bits/second (bits for the maximum burst size shaper) and cells/second (cells for the
maximum burst size shaper). Initially, the shapers are set to default values.

2 To enter a new shaper value, use the arrow keys on your keyboard to move to the
cell in the shaper table that you want to change.
n To set a new Sustainable Cell Rate or Peak Cell Rate shaper, enter the new
value in the bits/second (bps) column. The system automatically calculates the
cells/second (cps) based on the value you enter.
n To set a new Maximum Burst Size shaper, enter the new value in the cells
column. The system automatically calculates the bits based on the value you
enter.
