We only need these frames for synchronous links to maintain the link synchronicity. So how about Synchronously Inserted Idle Data Frame or SIID Frame. The term only is very misleading. Or Synchronously Inserted Frame with Idle Data SIFID or is an acronym with more than 3 letters verboten.

"OID Frame" = "Only Idle Data_field" Frame :-)
'FDFI' Frame for 'Frame Data Field Idle' Frame looks recursive :-)
More correct would be "Only Idle Data in Data Field" Frame = OIDDF Frame
We shall set the same term everywhere.
Idle Frame is misleading.
OID is not perfect but more correct and already defined for Packet TM Frame.
Then the simplest is to say that OID Frame is a short form for OIDDF Frame.
Let's discuss it in Colorado otherwise we enter in a loop.
