TDMA Full on route @ TDMA Internet

It depends on what dedicated bit rates your customers want and the capacity of your inroute TDMA receiver.

Some examples:

If your inroute receivers work at a fixed bit rate of 256 kbit/s and each customer is signed up for a dedicated 256 kbit/s, you need to allocate 1 inroute to each customer. This is a highly efficient arrangement and is the same as 6 SCPC carriers on the inroute back to the teleport.

If you have an inroute receiver bit rate of 256 kbit/s and each customer wants a dedicated 100 kbit/s, you need three inroutes, each sharing its 256 kbit/s capacity between two customers.  You need to configure the burst time plan so that each customer sends the same number of packets per second, all of the time. 2 x 100 kbit/s should fit into a 256 kbit/s TDMA receiver. There is some inefficiency due to the gap between the bursts and the burst headers.

If you have an inroute receiver bit rate of 256 kbit/s and each customer wants a dedicated 30 kbit/s, you need to use just one inroute TDMA receiver and share its capacity equally amongst your six customers.  You need to configure the burst time plan so that each customer sends the same number of packets per second, all of the time. 6 x 30 kbit/s might just about fit into a 256 kbit/s TDMA receiver. There is significant inefficiency due to the gaps between the bursts and the burst headers themselves.

If your inroute TDMA receiver has other bit rate options, and your customers want different dedicated bit rates from the above, then make up your own possible configurations.

The total transponder bandwidth (and thus cost) is the total of the dedicated capacities of all your six customers added together.

Regarding the outlink. If each customer wants 256k dedicated then you can operate a single 1536 kbit/s outlink carrier with traffic capacity allocated in the router so as to give equal 256 kbit/s and dedicated capacity to each of the six customers.
