Re: VM Architecture Questions?
1 - Varies by region, the 3 distinct franchise areas use different frequencies.
2 - Siames from customers property > DP > Secondary Mux (trasnfer from copper to Fibre) > Major Mux > Headend. This can still vary from region to region and is again dependant on the legacy architecture.
3 - Varies, especially if business services are fed from the same Fibre node as residential (which is the case on pretty much every fibre node in the field). As for modulation, this can vary depending on capacity requirements in any given area as far as im aware.
You wont get a clean cut answer on this, and if your writing a thesis and basing it on VM's network then you could write 100k words and still not be done! The network is massive with many different technologies being delivered.
Hope this helps
