zhoneSystemVoiceBandwidthCheck

Turns ON (true) of OFF (false) ATM bandwidth checks
for new voice calls going through the system.  The
bandwidth check is based on the configuration of
the Rx and Tx traffic descriptors used for the ATM
VC/CID that the call is going across.  If rtVBR is
being used then the SCR is used for the bandwidth
calculation cell rate.  If CBR is being used then
the PCR is used for the bandwidth calculation cell
rate.  For any other service category, a call is
always allowed and the voice quality is not
guaranteed.  The bandwidth calculation looks like
this (assume approx 180 AAL2 cells used for a
voice stream):
          
if ((rxCellRate - (180 * numActiveCallsOn VC)) < 180)
{
    /* reject call */
}
else if ((txCellRate - (180 * numActiveCallsOnVC)) < 180)
{
    /* reject call */
}
else
{
    /* proceed with call */
}
