I was reading the voip traffic analysis example. See http://www.cisco.com/univercd/cc/td/doc/cisintwk/intsolns/voipsol/ta_isd.htm#xtocid35
I cannot understand why to calculate the bandwidth needed on the link between the U.K. and the U.S., 96DSOs is used in the calculation instead of 48DSOs.
-> Full Rate: 96 DS0s * 26.4 kbps = 2.534 Mbps
Same goes for the bandwidth needed on the link between the U.K. and China. Shouldn't we use 96DSOs here instead of 72 DSOs?
-> Full Rate: 72 DS0s * 26.4 kbps = 1.9 Mbps
TIA for any enlightenment!
