[Css-csts] SLE Issues: open questions

[Alan Jeffries]

Dear CSTS Group,

I normally do not chime in, but I am working on the JPSS weather satellite
program and we are migrating our T&C and high rate science links to SLE. As
part of this we are moving to provider initiated binds, so we would be
interested in keeping the concept as an option.

May I inquire as to why these were considered for removal.

Best regards, Alan Jeffries
