During propagation, mainframe information overlays Internet information where data
fields exist on both the mainframe claim and the IDR, including situations where there
is no data present in the mainframe field (i.e., phone number).
EXCEPTION: The mainframe allegation of disabling conditions is added to the end of the EDCS
field only if there is room (i.e., the claimant didn’t use the full 1,000 characters
that are allowed when submitting the Internet disability report).
