So, in your example above that you put in your question, you mention the site has 2560kpbs to it, but not what the call rate is. If the call rate is less, then less will be required,
It means that if 10 locations with 1 Mbps each are to be connected on MCU, 10Mbps BW is required at the MCU location right??
In a very basic manner, yes, if the MCU needs to receive 10 calls at 1Mbps (assuming this is your call rate), then it needs to have 10Mb available. If you call rate is less, the you don't need as much - ie a call rate of 768k would be 10 x 768kpbs = 7.7Mb - so we'll call it 8Mbps. This also assumes that you don't have any other traffic. So, referring this back to your example, you have 80 sites, making 1Mbps calls, then you need to have 80Mbps on your WAN/Internet link, and the other 20 on your "intranet" don't really matter as they're on the local network where it'd be strange in this day and have to have less than 100Mb available locally.
Now, if this is a new site you are considering setting up, you will also need to take in to account that the Cisco MCU products are all now End of Sale, so you won't be able to purchase one, and should instead be considering using a CMS (if you need to keep everything on-prem), or utilising the Webex Cloud, in which case, you may be able to reduce the bandwidth requirements to your site as there will be less individual calls needing to traverse the link as the majority of the work will be done in the cloud.

Hi,
You can calculate the required BW by considering on how many video endpoints concurrent connections will be done from MCU.
Consider each call bandwidth to be around 1024 kbps and multiply this with number of codecs at each location.

Consider this :
Location A hosting MCU
Location B has 2 codecs
Location C has 3 codecs
If all codecs at location A and B are to get connected, then total bandwidth required at MCU will be =Location A (2 *1024KBPS ) + Location B (3*1024KBPS)
For higher video quality, you may consider higher bandwidth per call (example 2mbps per call ).
Also remember, QoS will only work if the video traffic is traversing through internal network, If your video traffic is going through INternet then the QoS will only work till your network perimeter.
