Deadlines for comments and reply comments will be determined once the NPRM appears in the Federal Register. When that happens, interested parties may file comments by using the FCC’s Electronic Comment Filing System (ECFS), posting to MD Docket No. 20-270. The FCC will consider all filed comments, once the proceeding has been opened to receive them.
