The obvious advantage that SCPC has over 1:1 TDMA service is the fact that there is less satellite overhead associated with SCPC. �iDirect TDMA will have said overhead (BTPs contained in the forward carrier and TDMA Headers, trailers, etc associated with the upstream carriers). �

The SCPC is not conteded as it is dedicated bandwidth but the TDMA may be so make sure you are happy with what is being offered on the TDMA side. ScotlandTDMA
