VCM Example:
Minimize Bandwidth
In this example we will fix our effective data rate of the
network to 21.2 Mbps (7 Mbps per site) and minimize
BW
Our most disadvantaged site is Site “C”
running at QPSK
4/5 FEC.
In CCM Mode we would need 13.33 Msps (18Mhz) of
total BW
For the purpose of this exercise we will discuss the fixed
DR
of the network with the understanding that each site
receives an unequal
share of the reduced BW
