Usage Guidelines This command configures traffic shaping between voice and data PVCs. Traffic shaping is required so
that the carrier does not discard calls. To configure voice and data traffic shaping, you must configure
the peak, average, and burst options for voice traffic. Configure the burst value if the PVC will carry
bursty traffic. Peak, average, and burst values are needed so that the PVC can effectively handle the
bandwidth for the number of voice calls.
