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
