ISP 10% rule is what you are asking about expected that average usage is 10% of total subscribers with bursts higher But remember to plan well for those bursts and ensure you have sufficient excess capacity. Certain events can have a significant effect on your burst pattern: some

[asterisk-users] OT: Bandwidth calculations and PCI/PCIX/PCIE

I found this interesting but old white paper at Dell.com tech solutions and another one from INTEL. It compares bandwidth usage of a PCI, PCI-X, PCI-E in33/66/100/133mhz bus and different technologies that can saturate the bus. It helped me understand the bandwidth required for TDM
